Abstract
Primary renal angiosarcoma is a rare tumor. Epithelioid variant of primary renal angiosarcoma is extremely rare and aggressive entity described in literature as a few case reports. It presents as solid looking renal mass as other renal cell carcinomas. Management is not well described due to scarcity of cases and aggressiveness of disease. We hereby report a case of epithelioid renal angiosarcoma in a 62-year female who presented with features of infected perinephric collection. Histopathological and immunohistochemical examinations of the renal specimen revealed lower polar renal tumor with atypical epithelioid cells having eccentric nuclei with coarse chromatin and eosinophilic cytoplasm, which were positive for vascular endothelial (FLI-1, CD 34, CD31 and factor VII) as well as epithelial (CKAE1/AE3) immune markers. Based on the histopathological and immunohistochemical findings, the patient was diagnosed with primary renal epithelioid angiosarcoma.
