Abstract
Background:Oral squamous cell carcinoma (OSCC) is one of the most frequently encountered malignancies of the oral cavity worldwide. Identification of reliable molecular markers may improve prognostic assessment and individualized management of affected patients.
Methods: This cross-sectional observational study was performed in the Department of Pathology, Dhaka Medical College, Dhaka, between September 2022 and August 2024. A total of 56 histopathologically confirmed OSCC cases, including 40 resected specimens and 16 mucosal biopsies, were enrolled according to predefined inclusion and exclusion criteria. Hematoxylin and eosin-stained slides and paraffin-embedded tissue blocks were reviewed in all cases. Immunohistochemical staining for CD10 and Masson trichrome staining were carried out on formalin-fixed paraffin-embedded tissue sections. Stromal CD10 expression was assessed and correlated with histological grade. Statistical analysis was performed using SPSS version 23, and a p-value below 0.05 was considered statistically significant.
Results: Most patients belonged to the 41–60 years age group (46.4%). The mean age was 61.0 ± 12.84 years, and males were more frequently affected than females with a ratio of 2.1:1. Positive stromal CD10 immunoreactivity was detected in 45 (80.4%) cases. The highest positivity was observed in poorly differentiated tumors (100%), followed by moderately differentiated tumors (96.3%) and well differentiated tumors (44.4%). The association between CD10 expression and histological grade was statistically significant (p=0.00001).
Conclusion: The present study demonstrated a significant relationship between stromal CD10 expression and increasing histological grade of OSCC. Therefore, CD10 may serve as a useful adjunctive marker for predicting aggressive biological behavior in oral squamous cell carcinoma.

Abstract
Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with multi-organ involvement. SLE affect on kidneys, mostly referred to as Lupus nephritis (LN) is of special interest for three reasons. First, lupus nephritis is one of the commonest types of organ involvement in this disorder, affecting as up to 45% of all patients with SLE. Second, it presents with a great variety of clinical and histopathological findings and thirdly, it greatly affects the morbidity and mortality of SLE patients. Thus, LN is one of the most serious SLE complications and the clinicopathological findings of LN are responsible for the ultimate prognosis of SLE. But these findings show geographical variation. Data on LN of Bangladeshi patients are rare in  literature and most of them describe mostly clinical features rather than the histomorphologic findings.
Objectives: To evaluate demographic, clinical, laboratory and histomorphological characteristics of LN patient and analyze correlations across different INS/RPS 2003 classes.
Method: A prospective, cross-sectional study was conducted at a tertiary diagnostic center in Dhaka from July 2024 to June 2025. Total fifty clinically diagnosed SLE cases with renal involvement were included in this study. The study group were underwent renal core biopsy. Histological evaluation and direct immunofluorescence (DIF) study were done on each specimen. Each case was classified according to the International Society for Nephrology/Renal Pathology Society (ISN/RPS) 2003 LN classification system and compared with the clinical, biochemical and immunological findings.
Results: The mean age was 28.3±12.2 years (range: 9-70), with female predominance (M:F ratio 1:4.5). Proteinuria was the leading presentation (96%), followed by hematuria (56%). ISN/RPS classification revealed Class IV as most frequent (40%), followed by Class III (26%). Class II (22%), Class V (08%) and Class I (04%). Proliferative LN (Class III/IV) exhibited crescent formation (30%), wire loop formation (34%) and necrotizing change (36%). Full house Immunofluorescence deposits were present in 85% of evaluable cases. Higher activity and chronicity indices were observed in Class IV lesions, correlating with worse renal function.
Conclusion: Class IV LN was the predominant and most severe subtype, strongly associated with adverse clinical, biochemical and histological features. Early renal biopsy and clinicopathological correlation remain indispensable for prognosis and therapeutic planning in Bangladeshi patients.

Abstract
Background: Papillary thyroid carcinoma (PTC) is the most prevalent thyroid malignancy globally, with BRAF V600E being its most common somatic driver mutation. This mutation constitutively activates the MAPK/ERK signalling pathway, contributing to aggressive clinicopathological behaviour and radioiodine (RAI) refractoriness.
Case Presentation: We report a 40-year-old female who presented with a thyroid nodule and was histopathologically diagnosed with classical PTC. Formalin-fixed paraffin-embedded (FFPE) tissue was subjected to targeted next-generation sequencing (NGS) using the oncoReveal™ Solid Tumor v2 Panel (48 genes) on the Illumina NextSeq™ 1000 platform. NGS revealed a pathogenic somatic BRAF c.1799T>A (p.Val600Glu) single nucleotide variant (SNV) in exon 15.
Conclusion: This case illustrates the complementary roles of histopathology and NGS in the WHO 2022 molecular classification framework for PTC. The identification of a pathogenic BRAF V600E mutation confirms molecular diagnosis, supports RAI-refractoriness risk assessment, and enables eligibility for Dabrafenib/Trametinib combination therapy, exemplifying precision oncology in thyroid cancer.
