Oral presentation of epithelioid angiosarcoma with first sign in the scapula: report of a case and review of the literature.

Occurrence of a primary or metastatic angiosarcoma in the oral cavity is extremely rare. The term "epithelioid angiosarcoma" (EA) has been used to designate a morphological variant of angiosarcoma characterized by poorly differentiated epithelial-like cells arranged in carcinoma-like fashion, but which still forms identifiable vascular channels. To our knowledge, EA in the oral region is extremely rare.
