Vaginal Cellular Angiofibroma: Report of a Rare Case with Literature Review.

Cellular angiofibroma (CA) is a relatively recently described, rare, benign soft tissue tumor that predominantly occurs in the vulvoperineal region. It was first described in 1997 as a mesenchymal-origin tumor composed of connective (fibrous) tissue and blood vessels. We report a case of vaginal CA in a 40-year-old woman who presented with pressure symptoms, incidentally diagnosed with a vaginal mass and clinically suspected as vaginal myoma.

Chromophobe Renal Cell Carcinoma with Sarcomatoid Differentiation (osteosarcomatous and chondrosarcomatous differentiation)-A Case Report and Comprehensive Review.

Chromophobe renal cell carcinomas (ChRCCs) have a good prognosis and comprise approximately 5-7% of renal cell carcinomas (RCCs). The sarcomatoid differentiation in RCC is found in around 5-10% of cases; however, in ChRCC, it is much less than in other RCCs and poorly responds to chemotherapeutic agents. A study by de Peralta-Venturina et al.

Expression of Programmed Death Ligand 1 [PD-L1] and Mismatch Repair Status in Squamous Cell Carcinomas of Cervix.

Background And Objectives: To assess mismatch repair (MMR) status and programmed death-ligand 1 (PD-L1) expression in squamous cell carcinomas of the cervix and their association with clinicopathologic parameters.

Material And Methods: Expression of PD-L1 and MMR status (MSH2, MSH6, MLH1, and PMS2) was assessed on 50 cases of SCCs of the cervix by immunohistochemistry.

Results: 80% of tumor cells and 84% of tumor-infiltrating lymphocytes showed PD-L1 expression.

Secretory carcinoma of parotid gland masquerading as acinic cell carcinoma on cytology: Case report and review of literature.

Secretory carcinoma is a relatively recently discovered low-grade salivary gland carcinoma with morphological similarities to its breast counterpart. The histopathological features of this entity are well established; however, the cytomorphological features are not well evaluated, leading to diagnostic challenges and pitfalls. We report a case of secretory carcinoma (SC) of the parotid gland, which was misdiagnosed as acinic cell carcinoma (ACC) on fine-needle aspiration cytology, to describe the cytological features.
