Abstract

Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular lesion that usually presents as a nonspecific erythematous-violaceous subcutaneous neoformation. The histopathological study, necessary for the confirmatory diagnosis, shows papillary proliferation of endothelial cells associated with thrombotic material. IPEH can simulate other lesions such as angiosarcoma, so the correct diagnosis of this entity is essential to avoid aggressive treatments. The resection with wide margins is usually enough.
