Glomuvenous malformations in a young man

Abstract

A young man presented with blue nodules on the trunk, face, and extremities that gradually increased in number and size. His mother had similar lesions. Initially, blue rubber bleb nevus syndrome was suspected, but histological findings confirmed the diagnosis of hereditary glomuvenous malformations. Making the correct diagnosis spares the patient unnecessary evaluation for the arteriovenous malformations of the gastrointestinal tract associated with the former diagnosis.
