Abstract

We present 12 cases of benign atypical vascular lesions of the lip with cytologic or architectural features that raised microscopically the possibility of angiosarcoma. The patterns encountered in these lesions, sometimes in combination, were the following: lobular capillary hemangioma in five cases; intravascular papillary endothelial hyperplasia in five cases; epithelioid hemangioma in four cases; and acquired progressive lymphangioma in one case.
