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.

摘要

我们报告了一例发生于一名65岁中国男性头皮的罕见皮肤上皮样血管肉瘤的细胞学特征。显著的上皮样特征在细胞学上可能模拟低分化癌、恶性黑色素瘤，甚至上皮样肉瘤。在得出最终结论之前，识别血管增生的细微细胞学特征、内皮标志物的免疫组化证明以及超微结构检查是必要的。
