Primary Angiosarcoma of the Gingiva

Abstract

A case of angiosarcoma involving primarily the gingiva in an 86-year-old woman is reported. The neoplasm was strongly positive for factor VIII-related antigen, negative for cytokeratins, and positive for vimentin, confirming the vascular nature of the tumor. The patient died from heart failure 1 month after surgical excision of the lesion without clinical evidence of metastasis.
