title: Cutaneous epithelioid angiosarcoma.
abstract: Three cases of cutaneous epithelioid angiosarcoma with solid pattern were studied by immunohistochemistry and electron microscopy. The neoplasms followed a slow, protracted course with local recurrences and regional lymph node metastases. The correct histological diagnosis was delayed by the close histological simulation of carcinomas, misleading ultrastructural findings, and largely negative immunohistochemical markers. Two of the patients have been followed for at least 48 months and are still alive. Some seemingly undifferentiated epithelioid angiosarcomas may entail a better prognosis than originally suspected.
