Abstract
Background: Oral Verrucous carcinoma (OVC) is a rare variant of well differentiated squamous cell carcinoma (SCC). Epithelial dysplasia and/or foci of invasion in OVC are indicators of worse prognosis. The aim of this study was to evaluate the epithelial dysplasia and invasion through the basement membrane in OVC.
Method: This was a cross-sectional observational study conducted at the Department of Pathology, BSMMU during 2021-2023 that included 45 cases of histologically diagnosed OVC. Demographic variables, presence or absence of epithelial dysplasia in routine H&E stain and presence or absence of invasion through the basement membrane by PAS stain were assessed. Thirty three cases were followed up and reports of the subsequent biopsies were collected. Research data were placed in a data sheet. Results of all cases were tabulated. Statistical analysis was performed on the tabulated data by Fisher’s Exact Test.
Result:  In this study, 33.3% cases revealed epithelial dysplasia in OVC and 11.5% cases showed invasive foci through the BM. We followed up the study cases and 15.6% cases were diagnosed as invasive SCC in subsequent biopsy. Statistical analysis revealed presence of invasion through the BM significantly higher in OVC cases having epithelial dysplasia. Similarly, in subsequent biopsy ISCC was found significantly higher in previously diagnosed cases of OVC having features of epithelial dysplasia.
Conclusion: Epithelial dysplasia in OVC signifies the increased possibility of its progression to conventional invasive SCC and is an important prognostic factor. So, earlier detection of epithelial dysplasia and/or foci of invasion in OVC will help the clinician in properly managing the patient.

Abstract
Background: Wilms Tumor 1 (WT1) is a transcription factor involved in cellular proliferation and differentiation, with emerging relevance in various malignancies including colorectal adenocarcinoma (CRC). The aim of this study was to assess the immunohistochemical expression of WT1 in colorectal adenocarcinoma and determine its association with age, gender, histological type, grade, stage, lymphovascular invasion (LVI), and perineural invasion (PNI).
Methods:This cross-sectional observational study included 97 histopathologically diagnosed cases of colorectal adenocarcinoma, selected using purposive sampling. The study was conducted at the Department of Pathology, Dhaka Medical College Hospital, while WT1 mmunohistochemistry was performed at the Immunohistochemistry Laboratory of Bangladesh Medical University, Dhaka. The study duration was from March 2021 to February 2025. Qualitative data were expressed as frequency and percentage. The Chi- square and Fisher’s exact test were used to assess the relation    between qualitative variables. A p-value less than 0.05 were considered as significant.
Results:Among 97 cases, 55% showed low and 45% showed high WT1 expression. High WT1 expression was significantly associated with mucinous type (p=0.0214), poorly differentiated tumors (p=0.0012), and advanced pathological T (p=0.0007) and N stages (p=0.0003). No significant association was observed with age, gender, LVI, or PNI.
Conclusion: WT1 immunoexpression associates with aggressive histopathological features in colorectal adenocarcinoma, suggesting its potential role as a prognostic marker.

Abstract
Introduction: Basal cell carcinoma (BCC) typically affects older persons with photo-exposed areas. Histological classification of BCC is essential for determining the risk of recurrence, assessing the percentage of histological groups, and comparing treatment results.
Aim: This study aimed to determine the frequency of various types of BCCs encountered in our practice, site predilection, age and sex distribution, and histological types that mostly involve the particular age and sex.
Method: This study was conducted in the department of Histopathology, National Institute of Burn and Plastic Surgery, Dhaka. The study was retrospective, observational, and conducted during the period from January 2020 to December 2021 (2 years).
Result: In this study, a total of 31 cases were included. Among them, the most frequent type found was nodular, the majority of cases involved the head and neck region, and were mostly seen in the 6th decade, with female predominance.
Conclusion: In the present study, the majority (93.5%) of the BCC were located on the head and neck region, the average cases was in the 6th decade, mostly found in female patients, and the nodular type of BCC was the most common variant.
