A Case of Intravascular Papillary Endothelial Hyperplasia on the Lip / 대한피부과학회지

ABSTRACT

Intravascular papillary endothelial hyperplasia(IPEH) is a solitary slowly enlarging, often tender, blue to red elevated nodule. The predilection sites include the head and neck region, and the extremities, especially the fingers. Histologically, IPEH is characterized by the well-circumscribed intravascular papillary structures, which are formed by fibrous cores that are lined by endothelial cells. We report a case of intravascular papillary endothelial hyperplasia developed on the unusual site of lip.
