Overview
Tissue biopsy may be helpful in the diagnosis of epithelioid sarcoma. Findings on biopsy suggestive of epithelioid sarcoma include white nodules with infiltrating margins, epithelial cells well blended with fusiform cells with intracytoplasmic vacuoles, and “pseudo granulomatous” proliferation of cells around acellular necrotic debris.
