Abstract

A 4-year-old boy presented with a 6-month history of a red papule on the nasal septum. Physical examination was otherwise unremarkable. A biopsy specimen showed an epithelioid sarcoma characterized by nodular collections of epithelioid tumor cells with central, tumor cell necrosis. By immunohistochemistry the tumor cells were positive for cytokeratin, epithelial membrane antigen, vimentin, and CD34, but negative for S-100, CD31, factor VIII-related antigen, CD68, actin, desmin and myoglobin. Epithelioid sarcoma is an uncommon tumor of uncertain histogenesis that typically arises in the extremities of young adults. Both the age of our patient and the location of his tumor are unusual, emphasizing the spectrum of presentations that may occur with epithelioid sarcoma. Epithelioid sarcoma should be considered in the differential diagnosis of granulomatous diseases and epithelioid tumors of children, even in unusual locations.
