Intravascular papillary endothelial hyperplasia (IPEH) is a rare, benign, non-neoplastic vascular lesion which usually occurs in the skin, subcutaneous tissue, and mucous membrane originating from any place where the vessel is located. It is most commonly seen in the head and neck region, while oral cavity involvement is rare. The clinical significance of IPEH is its histopathological similarity with Kaposi sarcoma, intravenous atypical vascular proliferation, spindle-cell hemangioendothelioma, and particularly with angiosarcoma. Surgical resection is the main treatment option. Herein, we present a case of IPEH of the masseter muscle which was resected successfully.Keywords: Head and neck tumor, intravascular papillary endothelial hyperplasia, masseter muscle, Massons tumor.
