Hemangioendotelioma epitelioide cutáneo extenso multifocal agresivo. Informe de un caso

Abstract

Epithelioid haemangioendothelioma is a rare vascular tumor, first described in 1975 by Dail and Liebow as a bronchioloalveolar carcinoma. Although it usually behaves like a low-grade neoplasm, cases have been reported in which the tumor shows a high grade of malignancy, spreading rapidly throughout the body. We present the case of a 41-year-old man with dermatosis in the left thigh with rapid extension to the abdomen; the initial differential diagnoses were metastatic carcinoma versus lymphoma.

When the histopathology was re-examined, a diagnosis of skin epithelioid hemangioendothelioma was confirmed and treatment with radiotherapy was initiated.

This tumour rarely affects the skin; there are only a few previously reported cases.
