Congenital Multiple Glomangiomas of the Breast Arranged in a Segmental Pattern

A 15-year-old female patient presented with multiple soft, well-defined dark-blue and purple-red papules and nodules, arranged in a segmental or band-like pattern, in the right breast and ipsilateral axilla. The lesions were present since birth, had enlarged with body growth, and were slightly tender to palpation. Histopathologic examination led to the diagnosis of glomangioma. We classify our patient as having a Type 1 segmental manifestation of glomuvenous malformations with histological features of glomangiomas.
