Three Cases of Intravascular Papillary Endothelial Hyperplasia on the Perinasal Area / 대한피부과학회지

ABSTRACT

Intravascular papillary endothelial hyperplasia is a rare nonneoplastic reactive process characterized by the development of endothelial papillary projection into the vascular lumen. It is now believed to be an unusual pattern of organization of a thrombus within a vein, or within one or more component vessels of various vascular abnormalities. Clinically, the most commonly involved site is the finger, but can also occur on the head and neck as a solitary, reddish or bluish nodule. Herein, we report three cases of intravascular papillary endothelial hyperplasia which developed on the perinasal area.
