Cutaneous epithelioid angiosarcoma: a potential diagnostic trap for cytopathologists

Diagn Cytopathol. 1997 Feb;16(2):160-6; discussion 166-7. doi: 10.1002/(sici)1097-0339(199702)16:2<160::aid-dc14>3.0.co;2-k.

Abstract

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.
