From: Vulvar “proximal-type” epithelioid sarcoma: report of a case and review of the literature
A) Histologically the tumor was composed of nodules of polygonal epithelioid and spindle cells circumscribe areas of central hyalinization and necrosis (H&E, ×200). B) The nodular pattern was composed by large cells with amphophilic cytoplasm. The tumor nodules were surrounded by and infiltrated by inflammatory cells. Nuclei were large and vescicolar and nucleoli were overshot (H&E, ×200). C) Immunostaining showed KERAE1-AE3+, VIM+, EMA-, CD34- ker 5-6-, s100-, ACTml-, MART1-, HMB45- (H&E, ×200).
