Abstract
Background: Glomerular disorders constitute one of the major causes of morbidity and mortality
in children and adult population. Diagnosing the pattern of glomerular diseases is important as the
treatment and outcome differs in different types. This study was undertaken to find out the various
morphological patterns of glomerular diseases among children at selected tertiary care hospital in
Bangladesh.
Methods: This cross-sectional study was carried out at the Department of Pathology, Bangabandhu
Sheikh Mujib Medical University (BSMMU), Dhaka from the period of September 2014 to June
2016. Renal biopsy samples of children with nephrotic syndrome and nephritic syndrome, children
having asymptomatic haematuria and isolated proteinuria and children presenting with acute and
chronic renal failure were included in this study. For routine histopathological examination, tissue
was preserved in 10% formalin. After completion of routine paraffin processing, hematoxylin and
eosin (H&E) and periodic acid Schiff (PAS) staining were done. For direct immunoflurescence
study, tissue was preserved in normal saline and processed according to standard protocol of
immunoflurescence study. Routine H&E and PAS stained sections of the renal biopsy samples
were examined for changes in glomeruli, tubules, interstitium and blood vessels. The site, pattern
and degree of antibody deposition in the renal tissue were observed by immunoflurescence study.
Final diagnosis was made by correlation of histopathological, immunofluorescence and clinical
findings.
Results: Mesangial proliferative glomerulonephritis (MesPGN) was the most common primary
glomerular disease diagnosed in patients followed by minimal change disease, IgA nephropathy,
membrano-proliferative glomerulonephritis and crescentic glomerulonephritis. Lupus nephritis was
the most common secondary glomerular disease diagnosed in patients.
Conclusion: The reported prevalence of different morphological patterns of glomerular diseases
among children in Bangladesh seems to be no definite pattern. In fact, the patterns vary according
to the geographical area, environment and racial background.

Abstract
Background: Small round blue cell tumors (SRBCTs) in children are a heterogeneous group of
neoplasms. Their diagnosis is very difficult due to their primitive character. Although the advent
of immunohistochemistry has improved the quality of diagnosis, some cases require molecular
analysis. However, the application of molecular tests is limited due to the lack of resources.
Nuclear expression of Cyclin D1 can be used as a diagnostic adjunct to conventional markers in
diagnosing small round cell tumors, especially when the diagnosis becomes difficult even
following the application of conventional markers.
Objectives: This study aimed to evaluate the immunoreactivity of Cyclin D1 in the common solid
small round blue cell tumors found in children below 15 years of age.
Methods: In this descriptive cross-sectional study, 64 confirmed (immunohistochemically and/or
morphologically) cases of SRBCTs including, Ewing sarcoma (31.25%), neuroblastoma (23.44%),
lymphoblastic lymphoma (21.87%), rhabdomyosarcoma (15.62%) and Wilms tumor (7.81%) in
children under 15 years were selected as samples by inclusion and exclusion criteria. Finally, the
immunoreactivity of Cyclin D1 in each case was assessed on the basis of staining pattern and
staining intensity.
Result: All cases of Ewing sarcoma and neuroblastoma exhibited nuclear expression for cyclin
D1. Seventy percent (14/20) of cases of Ewing sarcoma and 66.67% (10/15) of neuroblastoma
cases showed diffuse nuclear expression. Seventy percent (14/20) of cases of Ewing sarcoma and
93.33% (14/15) of neuroblastoma cases showed strong staining intensity (3+). In contrast, this
marker showed a negative reaction in rhabdomyosarcoma and lymphoblastic lymphoma, while it
was focally positive with moderate intensity in the blastemal component of 40% of cases of Wilms
tumor.
Conclusion: The present study suggests that cyclin D1 can be exploitable as a diagnostic adjunct
to conventional markers in confirming the diagnosis of Ewing sarcoma or Neuroblastoma.

Abstract
Objective: Breast lesions are heterogeneous diseases that consist of several distinct entities
with remarkably different characteristic features. The present study was conducted to assess
histopathological findings of breast lesions in excision biopsy samples.
Methods: This cross-sectional study was conducted in the Department of Pathology, Rajshahi
Medical College over a period of one year from July 2021 to June 2022. A total of 105 cases of
breast lesions were included in this study.
Result: Out of 105 cases of breast lesions studied, 59 cases (72%) were malignant and 46 cases
were benign lesions. Fibroadenoma (18 cases out of 46) was the most common benign lesion
followed by breast abscess (9 cases out of 46). On the other hand, invasive ductal carcinoma
was the highest occurred malignant tumour (59 cases, 56%). The age range of breast lesion was
15 to 75 yrs and highest incidence was in between 31-50 years (both benign and malignant).
Most of the breast lesions were occurred in left breast (62%).
Conclusion: Histopathological examination plays an important role in differentiating between
benign and malignant lesions. In the present study the most common benign breast lesion was
fibroadenoma and the most common malignant lesion was infiltrating ductal carcinoma. The
