Epithelioid sarcoma has been well characterized as a distincitve entity. In the classic form, it occurs in the distal extremities of young adults. However, in the proximal form, it was found mostly in the pelvis, perineum, and genital tract of young to middle-aged adults. Morphologically, the tumor cells had promient epithelioid or rhabdoid features with marked cytologic atypia, and grew in a multinodular pattern. Immunohistochemically, cytokeratin, epithelial membrane antigen, and vimentin were positive in the tumor cells. This reports dealt with 32-year-old male lesion on his perineum. The tumor shows typical features of proximal type epithelioid sarcoma. We also discussed pathological differential diagnosis and prognosis on this particular disease.
