We report on the cytologic features of a rare case of cutaneous epithelioid angiosarcoma of the scalp occurring in a 65‐yr‐old Chinese male. The prominent epithelioid features may cytologically mimic poorly‐differentiated carcinoma, malignant melanoma, and even epithelioid sarcoma. Recognition of subtle cytologic features of vasoproliferation, immunohistochemical demonstration of endothelial markers, and ultrastructural examination are necessary before a final conclusion may be drawn.
