ISSN 0001-5555 Sir, Intravascular papillary endothelial hyperplasia (IPEH) was first described by Masson (1) as a neoplastic lesion “vegetant intravascular haemangioendothelioma”. In 1976, Clearkin & Enzinger (2) proposed the term IPEH, which is currently known as a non-neoplastic reactive endothelial proliferation. The lesions are frequently situated in the deep dermis and subcutis of the fingers, head and neck. In subcutaneous localizations the lesion may appear clinically as a small, firm, superficial nodule imparting a red-to-blue discoloration of the overlying skin. We describe here a rare case of IPEH on the lower leg, which resembled malignant melanoma in appearance.
