title: Multinucleate cell angiohistiocytoma of the lower vermilion lip: an unusual site.
abstract: Multinucleate cell angiohistiocytoma (MCA) represent an uncommon benign fibrohistiocytic vascular lesion that sometimes may go undiagnosed because of its clinical and histopathological similarities with benign fibrous histiocytoma and other soft-tissue neoplasms especially when localized on oral cavity or semi mucosa. We report the case of a solitary multinucleate cell angiohistiocytoma on the lower lip of a 46-year-old woman suggesting that this rare lesion should be considered in the differential diagnosis of the oral soft-tissue neoplasms.
