Abstract

Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign reactive vascular lesion, characterized by thrombus formation and subsequent intravascular endothelial proliferation. IPEH should be differentially diagnosed from angiosarcoma because of their microscopic similarity. The clinical manifestation of IPEH varies according to involved site. We report a rare case of IPEH in the maxillary sinus of 35-year-old male presenting with epistaxis, which is completely removed without complications.
