Abstract
Accessory cells those that assist in an adaptive immune response. Many are antigen presenting cells. Some may play a role in the innate immune response as well.They are not lymphocytes or NK cells.Histiocytes and dendritic cells are usually considered to be part of this group. Since they are involved in the immune response, it can be difficult to separate reactive proliferations from neoplastic ones. This is what makes the diagnosis challenging.
During this talk I will introduce the classification and ontogeny of accessory cells and contrast two cases of dendritic cell neoplasms that belongs two completely different lineages.

Abstract
Cutaneous adnexal tumours, a large group of benign and malignant neoplasms thatshow morphologic differentiation towards one of the four primary adnexal structures present in normal skin: hair follicles, sebaceous glands, apocrine glands, and eccrine glands. This is thought, that through some poorly understood mechanisms, the activation of molecular pathways responsible fortumours originate from multipotential undifferentiated cells present within the epidermis or its appendageal structures may aberrantly express one or more lines of appendageal differentiation to varying degrees. The degree to which the eccrine, apocrine, sebaceous, and follicular differentiation pathways are activated and recapitulated gives a tumour its histologic features
Skin adnexal tumours, occurring most superficially as well as noticeable easily by patients, surprisingly are often a source of confusion amongst even experienced pathologists, might be, in part, related to the wide variety of tumours with complicated nomenclature, many well-described entities have overlapping features, tumours are often only partially sampled, and many cases do not fit neatly into well-established classification schemes.They may occur sporadically or may be markers of rare genetic syndromes, including Birt-Hogg-Dubé syndrome, Brooke-Spiegler syndrome, Cowden syndrome, and Muir-Torre syndrome.
This presentation is prepared to find out a simple algorithmic approach for adnexal tumours for the general surgical pathologists and also to shed light on some of the diagnostic dilemmas commonly encountered in our daily practice. At the end few interesting cases have been presented.
Conclusions: Awareness and review on the clinical and histopathologic features of primary cutaneous adnexal tumours, and knowledge of the diagnostic dilemmas they create, will be helpful to the general surgical pathologist in diagnosing these often challenging lesions
Data Sources: Pathology reference texts and primary literatures regarding adnexal tumors and cases as observed in my personal practice.

Abstract
Trephine biopsy histopathology is an important tool for the diagnosis of hematological pathology. Now a days this is widely practiced in Bangladesh. We faced some commondifficulties during trephine biopsy histopathology in our institute. I want to highlight and shear the common approach to trephine biopsy specimens that I followed to solve the diagnostic dilemma.
Clear Cell Sarcoma of Kidney – A Rare Case Report
Dr. Halima Khatun Doly
Assistant Professor, Department of Pathology, KhwajaYunus Ali Medical College, Sirajgonj.
Abstract
A 7-years-old girl was admitted in the PaediatricHaematology and Oncology Department of KhwajaYunus Ali Medical College with the complaints of abdominal distention and right sided abdominal mass for 3 weeks; there was no history of hematuria, headache, cough breathing difficulties or bone pain.Her physical examinations revealed an abdominal lump at right hypochondriac and lumber region; she was normotensive considering age. The CT scan revealed a large right sided renal mass suggestive of Wilmstumour which was about 14.0X13.0cm invading the pelvis and lower polar calyx without intra-abdominal lymphadenopathy and thrombus. Scanning of chest was normal and other initial investigations were unremarkable. With those evident she was initially treated by neo adjuvant chemotherapy according to SIOP- umbrella protocol for 4 weeks, then she was undergone open radical nephrectomy followed by histopathological examination was done.Macroscopically, the kidney measured about 11.0X9.5X8.5 cm with 8.0 cm long ureter and attached perinephric fat and fascia and small segment of renal vessels. Adrenal gland was grossly absent. On cut section, it showed a 10.5 cm large, sharply demarcated, hard, homogenous tan-graytumour that was almost occupying the entire kidney. Grossly the tumour confined to the kidney and invaded in to the renal pelvis. Ureter and renal vessels were unremarkable. No lymphnode could be identified from perinephric fat.Microscopically, the tumour was composed of anaplastic small plump to spindle cells arranged in diffuse, nests and cords separated by network of delicate arborizing fibrovascular septa. These cells had round,normochromatic nucleus with inconspicuous nucleoli and light staining indistinct vacuolated cytoplasm. Areas of necrosis, fibrosis, myxoid changes and hyalinization were also noted. The tumour had invaded into the renal pelvis and sinuses. The renal capsule, perinephric fat, Gerotafascial margin, renal vein and ureteral resection margin were free of tumour.The histological findings firmly established the diagnosis of renal clear cell sarcoma with pathological stage: ypT3aNxMx. On the basis of histopathological report patient received adjuvant chemotherapy containing doxorubicin and had been started with planning of radiotherapy.On clinical follow up at 3 weeks after post nephrectomy and 1st cycle of adjuvant chemotherapy, patient was found apparently healthy.

Abstract
Primary breast cancer is themost common malignancy in females . Metastasis to the breast from rectal carcinoma is extremely rare and accounts for 0.43% ofall breast malignancies . Breast metastasis can mimic a primary breast cancer and may present confusing diagnostic problems. The most common tumor that metastasize to the breast is a contralateral breast carcinoma followed by malignant melanoma, lymphoma, sarcoma , lung , ovary, kidney , stomach and carcinoid tumors .
Here, we report a case of a 18-year – old female presented with right breast lump in outpatient department of a private hospital. Lumpectomy was done and it was reported as mucinous carcinoma of right breast . She again developed right breast lump five months after the first operation . Core biopsy was done and reported as mucinous carcinoma of right breast with recurrence. At the same time she noticed per rectal bleeding and alteration of bowel habit . Colonoscopy reveals rectal growth and rectal biopsy shows mucinous adenocarcinoma.
The immunohistochemistry findings from right breast lump and rectal growth shows CK 20 positive , CK 7 negative , GATA-3 negative and CDX2 positive. Histomorphological evaluation and immunohistochemistry are in support of rectal adenocarcinoma (primary) and the breast reveal metastatic adenocarcinoma of colorectal origin .
Conclusion
Histopathology with immunohistochemistry is very important tool in the diagnosis of cases of this nature but the clinical correlation should be taken into consideration at multidisciplinary team meetings to decide the final management of the patient.

Abstract
The incidence of breast cancer is rapidly increasing at present and it will strike 1 in 9 women over a lifetime. Nowadays younger patients are being diagnosed with breast cancer. The importance of early diagnosis cannot be underscored as management and survival is markedly improved with early stage of breast cancer. The most common malignant breast lesion in our day to day practice is infiltrating duct carcinoma, not otherwise specified (IDC-NOS) followed by invasive lobular carcinoma. Apart from these, there are more than dozen variants of breast cancer and few rare lesion in benign and intermediate category which are less common but it is important to know their main characteristics to make the best treatment choice and better prognosis. It is need of hour to discuss important neoplastic and non neoplastic breast lesions that are less known and less appreciated. The diagnosis of breast lesions are done by various laboratory diagnostic procedures viz. FNAC ( Fine Needle Aspiration Cytology), Core needle biopsy examination and Histopathological examination of whole specimen. FNAC can be performed on any clinically palpable lumps or roentgenographically detected non- palpable lesions of the breast. The major limitations of this method is that definite diagnosis of some lesions can be difficult to make on the basis of cytology. Core biopsy is useful in the evaluation of lesions likely to be low histopathological grade and in those presenting as architectural distortions, for which FNA cytology may fail to prove a diagnosis. Core biopsy is definitely a robust and reliable diagnostic modality, but carries with it disadvantages in terms of a longer turn- around due to the tissue processing time, patient discomfort during the procedure and higher complication rate. Histopathological examination of whole specimen of breast is the gold standard modality for final diagnosis of any breast lesion. We are going to discuss role of various diagnostic modalities in rare neoplastic and non neoplastic lesions of breast.

Abstract
Background: Lung cancer is one of the leading cancer related deaths both in male and female all over the world as well as in Bangladesh. Non small cancer is the majority of lung cancer that leads to very rapid fatality without appropriate treatment. Recent advances of molecular and genetic study like Epidermal growth factor receptor (EGFR) mutation, ALK rearrangement, ROS1 mutation and PDL1 study by RT-PCR and immunohistochemistry (IHC) brings the significant changes in the treatment protocol and increases the survival of patients with improving the quality of life.
Objectives: Our goal is to investigate the prevalence of EGFR mutation, ALK, ROS1 and PDL1 study in non-small cell carcinoma of lung in Bangladesh and their treatment outcomes.
Methods: Study carried out in Armed Forces Institute of Pathology (AFIP), Dhaka from Jan 2022 to Dec 2023 with all patients diagnosed in non-small cell carcinoma of lung (Both Adenocarcinoma and Squamous cell carcinoma) . All molecular study of EGFR were done by RT PCR after DNA extraction and ALK1, ROS and PDL1 were done by IHC in Ventana machines and results were statistically analyzed in SPSS version 20. Follow up the patient after targeted therapy combined with or without chemotherapy and reviewed the cases.
Results: In this study total 220 cases non-small cell carcinoma were included. The mean age was 63.5 yrs. (41-80 years) and male (n=-160) – female (n=60) ratio was 2.6:1. Histopathological findings where Adenocarcinoma were predominant 81.8%(n=180), followed by Squamous cell carcinoma 14.54%(n=32), Adeno-squamous cell carcinoma 2.27%(n=05) and large cell carcinoma 1.36%(n=03). Molecular study revealed EGFR mutation were 20% (n=44), ALK 2.7%(n=06), ROS1 1.8%(n=04) and PDL1 3.6%(n=08). Regarding EGFR mutation (n=44), most common mutation was Exon 19 deletion 50%(n=22/44), 18.18%(n=08/44) in Exon 18, 27.28% (n=12) in Exon 20 among them 18.2% and 9.17% in T790M and S7681 mutation respectively. L858R mutation was 4.55% (n=2/44) in Exon 21. Most of the mutation found in Adenocarcinoma of lung and it was 98%. By observing therapeutic response, stage II and stage III cases were well responded than stage IV. Targeted therapy more effective than conventional chemotherapy.
Conclusion: As Bangladesh is developing country, all patients are not economically solvent to do the all-molecular studies, however basing on available resources, those capable to performed the test, they are well responded in targeted therapy in Exon 18 and Exon 19 deletion than Exon 20 and Exon 21 deletion. Immunotherapy in PDLI positive patients were well responded.

Abstract
The establishment and maintenance of quality Anatomic Pathology Services (APS) is important to reduce preventable mortality from cancer. APS plays a crucial role in cancer diagnosis, treatment, and prevention at both individual and public health levels. However delivering quality APS is hindered by insufficient human capacity, inadequate education and training, and inadequate quality standards and accreditation.
Strategies for implementing quality improvement programs in APS include Firstly, incorporating education in quality and safety into healthcare and pathology curricula at all levels to empower local pathologists and laboratory scientists to assess and improve the quality of APS. Secondly, developing sustainable infrastructure and resources for APS including laboratory facilities and equipment. Thirdly, implementing quality assurance programs and patient safety measures to enhance the reliability and safety of laboratory services is critical. Fourthly, there is an emphatic need for a cultural shift towards quality improvement and patient safety at the organizational level, involving frontline healthcare institutions and professional organizations. Finally, establish partnerships between low-and middle-income countries (LMICs) LMICs and upper middle- and high-income countries (UMHICs) to facilitate knowledge exchange and accelerate quality improvement efforts.
While progress has been made in quality improvement efforts for clinical laboratory services in LMICs, pathology service requires specific attention due to its unique challenges and high risk. By implementing these strategies, the quality and safety of APS can be improved thereby contributing to reducing cancer mortality, and aligning with the sustainable development goal (SDG) goals set by the World Health Organization (WHO).

Abstract
End-stage renal disease (ESRD) patients in Bangladesh increases rapidly. No definite country based study is available regarding the exact statistics. According to hospital statistics, approximately 35,000 to 40,000 patients in this country report with ESRD each year. Renal replacement therapy (RRT) is the treatment of choice which includes dialysis and renal transplantation. Renal transplantation is the better choice as it leads to longer survival and enables superior quality of life. Unfortunately, only 25% of ESRD patients in Bangladesh can access RRT, and, among them, only 2% undergo renal transplantation (RT).
Renal biopsies remain the gold standard to determine the cause of graft dysfunction, which occurs in about 30% of recipients early after transplant and at a rate of 2% to 4% per year after the first year.
Biopsies are particularly useful to guide treatment in ambiguous clinical situations and are used in combination with other diagnostic tests, including imaging and laboratory tests.
Indication of renal transplant biopsy includes a) when there is a persistent, unexplained increase in serum creatinine b) when serum creatinine has not returned to baseline after treatment of acute rejection c) every 7–10 days during delayed graft function d) if expected kidney function is not achieved within the first 1–2 months after transplantation e) kidney allograft biopsy is also suggested when there is new onset of proteinuria or unexplained proteinuria ≥3.0 g per 24 hours.
Biopsies best distinguish acute rejection, acute tubular necrosis, infections such as polyomavirus nephropathy (PVN), thrombotic microangiopathy (TMA), recurrence of original disease, CNI toxicity, and chronic rejection.
BANFF working classification of kidney transplant pathology is a well-accepted method worldwide to classify the causes of renal allograft dysfunction. The BANFF classification has provided a standardized approach to diagnosing and grading kidney allograft rejection for over 3 decades. Its contributions have led to improved communication among pathologists and facilitated advancements in research and clinical practice in the field of kidney transplantation.
Polyps of the Gastro-Intestinal Tract: The Unusual Types
Mohammed Kamal
Visiting Professor of Pathology, BSMMU and
Chief Consultant Pathologist, The Laboratory,
Dhaka. Bangladesh.
Abstract
Polyps are intraluminal projections of mucosal or submucosal tissue. These can be a serious health concern, as these abnormal growths can lead to cancer in some cases if left untreated. These are most commonly found in the stomach and intestines, making early detection and treatment vital. By taking action and addressing polyps early, the risk of developing cancer can be greatly reduced and proper treatment can be ensured.
Screening tests such as endoscopy, barium contrast x-ray, various DNA tests in stool and occult blood tests are used to detect polyps arising from the mucosa. The current clinical practice involves endoscopic detection followed by histological confirmation. The Paris classification divides lesions into two categories: polypoid (elevated) or nonpolypoid (flat). Image-enhanced endoscopy, which is the basis of NICE classification, is a highly accurate tool used to diagnose the histologic class of a polyp.
A small number of submucosal tumors or tumour like lesions can present as polyps in the gastrointestinal tract. These growths can be neoplastic, hamartomatous (abnormal tissue growth), or non-neoplastic inflammatory in nature. To diagnose these tumors, clinicians have to use a combination of tools including standard endoscopy, endoscopic ultrasound (EUS), computed tomography (CT), magnetic resonance imaging (MRI), fluorodeoxyglucose-labeled positron emission tomography (FDG-PET) etc. To confirm the diagnosis, an excisional biopsy is mandatory.
A few polyps exhibit unusual and atypical features that demand clinical and histological correlations, making them difficult to diagnose according to well-defined lesion criteria. This presentation will showcase some of these challenging cases and will delve into the intricacies of these challenging cases, exploring the clinical and histological features that differentiate them from well-defined lesions.

Abstract
Over the past few decades there have been dramatic rise in eosinophilic esophagitis (EE) patients, who were thought to have gastroesophageal reflux disease (GERD) but who did not respond to medical and/or surgical GERD management. Whether, this emergence is of a true diagnostic nature or simply of an enhanced awareness. Recognition of this disease for the gastroenterologist has become paramount because of its differentiation from GERD not only from an etiologic but especially from a treatment point of view.
The EE is a chronic inflammatory, immunoallergic disease of the esophagus that represents the most common eosinophilic gastrointestinal diseases (EGIDs). The EE is a clinicopathological disease characterized by (1) Symptoms including but not restricted to food impaction and dysphagia in adults, and feeding intolerance and GERD symptoms in children; (2) dense esophageal eosinophilia (≥15 eosinophils/HPF) with squamous epithelial hyperplasia; (3) Exclusion of other disorders associated with similar clinical, histological, or endoscopic features, especially GERD. EE is a polymorphous disease that presents with various changes in esophageal caliber, and subtle changes in mucosal appearance, which lead to biopsy collection as a key procedure for diagnosis. The EE has now become an emerging global problem. It’s not time to put away the biopsy forceps but gastroenterologist should put an effort to obtain biopsy from esophagus in symptomatic patients. In EE, the variable distribution of eosinophils throughout the esophagus complicates the diagnosis; to avoid false-negative histologic results because of sampling errors, the endoscopist must seek biopsy from multiple areas.
The management must be multidisciplinary, including gastroenterologists, pathologists, allergologists, and also dietitian.

Abstract
In Bangladesh, the incidence of intrathoracic malignancies is rapidly increasing, with many cases being diagnosed at late stages. Pathologists often diagnose these cases using small biopsy specimens, obtained through procedures such as EBUS/TBNA, fine needle aspiration, endobronchial biopsy, percutaneous needle core biopsy, or pleural biopsy. Obtaining a satisfactorytissuesample is challenging for radiologists, respiratorymedicine specialists, and interventional pathologists.
Oncologists rely on predictive biomarkers and immune checkpoint inhibitors, which are commonly evaluated using techniques such as immunohistochemistry (IHC), reverse transcription-polymerase chain reaction (RT-PCR), and next-generation sequencing (NGS). Morphological diagnosis alone is insufficient for determining optimal treatment strategies, although it plays a key role in some malignancies. The current IASLC histological grading system for non-mucinous NSCLC has been proven effective in reflecting tumourbehaviour.

Abstract
Lymphoma is a heterogenous disorder. WHO classifies lymphoma on the basis of morphology, cell lineage, genetical aberrations and aggressiveness. Without immunohistochemistry, subclassification of lymphoma is not possible. Usually, a large panel of antibody markers are used to get the conclusive result. In many cases genetical evaluation is also necessary. Immunohistochemical markers are expensive which most of the patients in this country face difficulty to bear. However, using limited number of antibodies in the panel of markers can help reach a reasonably conclusive diagnosis in most of the cases. A number of lymphoma cases are presented here including non-Hodgkin lymphoma- nodal and extra nodal and Hodgkin lymphoma with the help of a limited panel of antibodies that includes- LCA, CD3, CD20, CD5, CD23, PAX5, CD10, BCL-2, BCL-6, MUM-1, Cyclin D-1 etc. Antibody markers are used in batches where results obtained from first batch dictate choice of markers in the next batch and so on. This helped reduce use of unnecessary markers as well as cost of the test. In case of DLBCL Hans’ algorism was used to identify more aggressive subtype (i.e. ABC type). Bare minimum markers were used to classify small B cell lymphomas that include CD5, CD23 and CD10. Immunohistochemical tests of all the cases were performed in the histopathological laboratory of Anwer Khan Modern Medical College Hospital, a Dhaka city based private medical college.

Abstract
Background: Hetrotopic ossification is rare in gall bladder with very few reported cases. The pathogenesis is not clearly understood but inflammation and irritation might predispose the condition.
Presentation of case: A female of 18 yrs underwent laparoscopic cholecystectomy due to persistent upper quadrant pain, nausea and post prandial vomiting. The Ultrasound reported a polyp with features of cholecystitis. The post operative period was uneventful.The Histopathology revealed fibromuscular hyperplasia, infiltration of chronic inflammatory cells, including foamy histiocytes in the lamina propria. Rokitansky – Aschoff sinuses were present. In the focus of polypoid area it showed denuded epithelium, mature bone formation and marrow materials. No metaplasia, dysplasia or evidence of malignancy noted.
Conclusion: We report a rare event of osseous metaplasia of the gall bladder which was incidental without known clinical significance. Stromal fibroblastic activity and active inflammation may play arole in osteogenic stimulation in gall bladder mucosa.

Abstract
TA-GVHD is a rare, usually fatal complication of transfusion of blood and blood products containing viable T lymphocytes. Very rarely it may arise in an immunocompetent individual. There is an increased risk of TA-GVHD following bypass grafting and other surgical procedures where blood transfusion are required. Here we present a case of a 57 old patient who received 5 units of whole blood from his close relatives perioperatively and manifested unexplained anaemia, fever, skin rash which later became desquamating & cheilitis on his 19th POD. His CBC report suggested pancytopenia indicating bone marrow failure. Skin biopsy confirmed the diagnosis as chronic TA-GVHD, lichenoid type. His liver function deteriorated and he died subsequentlyon his 32nd POD. TA-GVHD develops when immunocompetent T lymphocytes of transfused blood able to engraft in the recipient’s lymphoid tissues that fail to reject them. Those lymphocytes mediate immune response causing damage and dysfunction of the skin& other organs. Our patient showed all features of TA-GVHD that was complicated by sepsis and multiorgan failure despite aggressive management. Pathologists, surgeons, physicians and transfusion centers must be aware of this sinister complication of perioperative blood transfusion in any surgery, including CABG. Though fatal in >90% cases, it can be prevented by using irradiated blood. Patient parties must also be discouraged to donate blood to avoid this grave outcome.

Abstract
Background: Primary myelofibrosis (PMF) is a rare hematological malignancy with higher mortality and morbidity due to progression of bone marrow fibrosis (BMF). The amount of bone marrow reticulin and collagen fibrosis is detected by reticulin and Masson’s trichrome (MT) stains, respectively. The study aimed to explore the pattern and degree of BMF in PMF cases with above mentioned special stains along with conventional Hematoxylin & Eosin (H&E) stain.
Methods: Thirty-six histopathologically suggested or diagnosed cases of PMF were studied at the Department of Pathology, BSMMU. Paraffin blocks of trephine biopsy specimens of the selected cases were collected. H&E, reticulin and MT stains were applied on the re-cut sections. Extent of fibrosis was assessed by examining the sections with each special stain using a proposed four scaled semiquantitative bone marrow fibrosis (MF) grading systems. The cases were divided into two groups. Patients having grade MF-0 to MF-1 were considered absent pathological BMF. Those cases with MF-2 to MF-3 were encountered with present pathological BMF.
Results: In this study, nineteen (52.8%) PMF cases had pathological BMF diagnosed by only H&E. Moreover, thirty-four (94.4%) patients had pathological BMF corresponding to MF-2 to MF-3 detected by special stains.
Conclusion: Significantly higher (p<0.05) detection of pathological BMF cases with use of additional special stains recommends that, both reticulin and MT stains can be used routinely to assess BMF properly according to special grading system.

Abstract
Definition: Carcinoma of unknown primary (CUP) by definition is a metastatic syndrome with an unidentifiable primary tumor, even after baseline diagnostic workup to seek the primary site. CUP constitutes 3-5% of all cancer diagnoses worldwide.
Diagnostic workup needed: Biopsy, Light Microscopy and Immunohistochemistry (IHC), Tumor markers, Tissue of origin, Assays by molecular techniques (RT-PCR, microarray, NGS). Patients are initially categorized based on the findings of initial biopsy: adenocarcinoma, squamous-cell carcinoma, neuroendocrine carcinoma and poorly differentiated carcinoma.IHCis the gold standard in the diagnosis of CUP. In practice, four primary sites (breast, ovary, prostate and thyroid) should first be investigated. The use of IHC has some pitfalls which necessitates molecular tumor profiling (NGS, RT-PCR, microarray), mutation-specific antibodies and other ancillary diagnostic tools.Appropriate patient management requires several clinical and pathological features. Current standard treatment of the unfavorable risk subtype requires assessment of prognosis and consideration of empiric chemotherapy.
Keywords: Carcinoma of unknown primary, immunohistochemistry, molecular techniques

Abstract
Background: At least six different mathematical models of cancer and their countless variations and combinations have been published to date in the scientific literature that reasonably explain epidemiological prediction of multi-step carcinogenesis. Each one deals with a particular set of problems at a given organizational level ranging from populations to genes. Any of the models adopted in those articles so far do not account for both epidemiological and molecular levels of carcinogenesis.
Methods: We have developed a mathematically rigorous system to derive those equations satisfying the basic assumptions of both epidemiology and molecular biology without incorporating arbitrary numerical coefficients or constants devoid of any causal explanation just to fit the empirical data.
Results: We generalized all the epidemiological and molecular data using our derived equations through linear and non-linear regression and found all the necessary coefficients to explain the data. We also tested our equations against non-neoplastic conditions satisfying equivalent mathematical assumptions.
Conclusion: The aim of this treatise is not only to provide some novel insight into the mathematical modelling of malignant transformation but also to revive the classical tools we already have at our disposal to pave the way towards novel insight into integrated approaches in cancer research.
Keywords: Mathematical modeling, epidemiology, cancer.

Abstract
The serous borderline tumours are the most common types of borderline ovarian tumours, also referred to as atypical proliferative serous tumours. They often cause differential diagnostic difficulties even for the experienced pathologists.All borderline tumours are distinguished from their malignant counterparts by the absence of stromal invasion. However, diagnosis of serous borderline tumours of ovary is sometimes complicated when there are issues like ovarian surface involvement by the serous tumour, micropapillary growth pattern, frequent presence of endosalpingiosis in pelvic lymph nodes, presence of peritoneal implants, and foci of microinvasion. A careful gross examination of the ovarian tumour, optimum sampling from different areas of the tumour, and thorough microscopic examination may help to resolve the issues and come to a conclusive diagnosis, thereby ensuring optimum patient care.

Abstract
Breast cancer stands as the prevailing invasive cancer globally, bearing high mortality rates among women. Existing evidence indicates diminished survival rates in younger patients. Consequently, this study endeavors to assess and contrast the pathological features of breast cancer in women under 40 years of age with their older counterparts. Conducted as a cross-sectional analysis, this study encompasses 560 patients diagnosed with breast cancer, seeking treatment at Mymensingh Medical College Hospital (MMCH), Community Based Medical College (CBMCB) and several private hospitals in Mymensingh. The gathered data incorporates information such as age, residential area, occupation, tumor histopathology, TNM classification, staging and status of hormone receptor. The patients’ mean age (standard deviation) was 49.7±11.9 years, with 20.5% below 40, most were from rural areas and were housewives. Ductal carcinoma prevailed as the most common histopathologic type (87.67%). However, younger patients exhibited a higher prevalence of lobular and other rare carcinomas compared to their older counterparts (p=0.04). Additionally, the younger group demonstrated larger tumor sizes (p=0.01), lymphatic node involvement (p=0.04) and advanced staging (p=0.004). Notably, younger age showed more negativity for estrogen & progesterone receptors. The results suggested that women under 40 years old exhibit more aggressive tumor characteristics and a more severe form of breast cancer compared to their older counterparts.

Abstract
Colon cancer is one of the most prevalent cancer worldwide. It ranks third in terms of incidence following lungs and female breast cancer. According to Globocan 2022 data, in case of Bangladesh it ranks 10th in terms of incidence and mortality. World health organization start a project on tumor classification named as blue book on cancer since 1956 and published by IARC based on France. Latest 5th edition of one of these series named as “WHO Classification of Tumors, Digestive system tumours”. Malignant tumors of the colon are mostly adenocarcinoma. NET, Lymphoma, GIST and smooth muscle tumors are also evident. Hereditary syndromes, genetics, environment, diets are responsible for carcinoma development. Newer modern techniques discover more and more underlying genetics of these cancer development and progression that will help to fight cancers in the future. Conventional way of diagnosis of colon carcinoma is mainly histopathological study. Immunohistochemistry, molecular techniques, genetic studies also widen the whole scenario of cancer day by day and make us more capable of fighting these worldwide epidemics. Surgery, radiotherapy and chemotherapy has failed to reduce mortality in advanced stages of colon cancer. Targeted therapies, immunotherapies are now being applied on advanced colon cancer. Clinical trials are currently underway for novel cytotoxic agents.

Abstract
Dyshormonogenetic goiter is a rare cause of congenital hypothyroidism occurring due to a lack of enzymes necessary for the synthesis of thyroid hormones. It is morphologically characterized by architectural and cellular pleomorphism that may mimic thyroid malignancy and cause difficulties in differential diagnosis.
We report a new case occurring in a 9-year-old girl with history of hypothyroidism since two years of her age and treated by thyroxin. She developed a progressively slow growing multinodular goiter. Computed tomography revealed an ill-defined nodular lesion in left lobe with heterogenous densities and a small hypodense, nodular lesion on the right thyroid lobe. A total thyroidectomy was performed.
Gross examination revealed an enlarged and multinodular thyroid gland. Histologically, the features were consistent with dyshormonogenetic goiter.
The literature on the histopathology of dyshormonogenetic goiter is reviewed and clues to avoid inappropriate overdiagnosis of malignancy are given.

Abstract
Background: Pineal parenchymal tumors (PPTs)are rare and the incidence ranges from 0.4-1% in adult population. The morphology of tumor varies from the well differentiated pineocytoma to poorly differentiated pineoblastoma. Pineal parenchymal tumor of intermediate differentiation (PPTID) and papillary tumor of pineal region (PPTR) are in between.This single institutional based study aimed to find out the frequency and histologic spectrum of pineal parenchymal tumors in a tertiary level hospital in Bangladesh.
Objective: To evaluate the frequency of pineal parenchymal tumors and their histomorphology along with immunohistochemistry at a tertiary level hospital in Bangladesh.
Methods: It is a cross sectional observational study based on archival tissue and records.
Result: A total of twenty cases were searched out from 2019-2023 (5 years). Themale to female ratio being 1.5:1. Pineal parenchymal tumor of intermediate differentiation (40%) were the most common pineal parenchymal tumors found mainly in adult population while pineoblastomasmore frequent in pediatric group. Histological variations were observed in all cases. Out of 20 cases of PPTs,16(80%) cases were synaptophysin positiveand 10(50%) cases were positive for NSE. All cases of PPTs were negative for EMA and PanCK. Ki67 labelling index was lowin pineocytoma (<1%) and higher in pineoblastoma (25-60%).
Conclusion: Pineal parenchymal tumor of intermediate differentiation (PPTIDs) is the commonest type of pineal parenchymal tumor. It occurs mainly in adult.Pineoblastoma is the most frequent one for pediatric population. For diagnosis of PPTs, only histopathology is not enough, immunohistochemistry should be used as diagnostic adjunct.

Abstract
Interstitial lung diseases (ILDs) are defined as a group of diffuse lung parenchymal diseases which result from damage to the lung parenchyma caused by different degrees of inflammation and fibrosis.It refers to variable patterns / diseases characterised histologically by inflammatory infiltrate in the interstitium with variable degree of fibrosis. Correlation of clinical, radiological and pathologic features is often required to reach a correct diagnosis of ILD. According to the updated American Thoracic Society–European Respiratory Society classification, idiopathic interstitial pneumonias (IIPs) are ILD’s of unknown etiology sharing common clinical features and can be categorised into (a) “chronic fibrosing IIPs” (idiopathic pulmonary fibrosis (IPF) and idiopathic nonspecific interstitial pneumonia (NSIP)), (b) “smoking-related IIPs” (respiratory bronchiolitis associated interstitial lung disease (RB-ILD) and desquamative interstitial pneumonia (DIP)), and (c) “acute or sub acute IIPs” (cryptogenic organizing pneumonia (COP) and acute interstitial pneumonia (AIP)) and (d) “rare IIPs” (lymphoid interstitial pneumonia (LIP) and idiopathic pleura-parenchymal fibro-elastosis (IPPFE)). Furthermore, it has been acknowledged that a final diagnosis is not always achievable, and the category “unclassifiable IIP” has been proposed. The diagnostic interpretation of the IIPs is often challenging because other diseases with a known etiology (most notably, connective tissue disease and hypersensitivity pneumonitis) may show similar morphologic patterns. Indeed, more emphasis has been given to the integration of clinical, computed tomographic (CT), and pathologic findings for multidisciplinary diagnosis. Typical CT-based morphologic patterns are associated with the IIPs, and radiologists play an important role in diagnosis and characterization. Optimal CT quality and a systematic approach are both pivotal for evaluation of IIP. Interobserver variation for the various patterns encountered in the IIPs is an issue. It is important for radiologists to understand the longitudinal behavior of IIPs at serial CT examinations, especially for providing a framework for cases that are unclassifiable or in which a histologic diagnosis cannot be obtained.

Abstract
Human dissections, autopsies, microscopy, as well as the development of histopathological, immunohistochemical, and molecular techniques are involved in the history of pathology. Our understanding of anatomy and disease improved through these methods, and models of pathogenesis were refined over time.
Pathology plays the pivotal role in driving healthcare to understand diseases. Continuing improvements in digital technologies could make this subject more efficient and more scalable. The job of pathologists could be transformed into a more creative and data-driven profession while allowing patients to receive diagnoses faster and more accurately. Let’s see what the digital future of pathology looks like! Key milestones in the evolution of pathology as a branch of medical science, from ancient civilizations to the modern day are discussed here.
