[Cutaneous metastatic angiosarcoma of the forearm].

Cutaneous angiosarcoma are rare tumours and occur particularly rarely on the extremities. There are only a few reports in the literature concerning their clinical and catamnestic behaviour. We report the case of a 57-year-old male North African with a large exophytic and nodular tumour of the left forearm that showed a vasoformative histological pattern. The endothelial cell origin was proven by immunocytochemistry using endothelial cell antibodies such as anti-vWf (syn.:anti F VIII R:Ag), UEA I and the monoclonal antibody BMA 120. The patient's history revealed that the neoplasm had grown slowly for more than 15 years. After partial resection, the tumour enlarged rapidly and the patient died of widespread metastases.
