Vascular Malformations and Hemangiomas

Abstract: We present the case of a 54‐year‐old man with a brown‐red nodule on the hand that had been present since early adulthood. Histology of the excisional biopsy revealed hyperplasia and proliferation of eccrine, apocrine, lipomatous, and vascular structures. These findings were most characteristic of the entity known as eccrine angiomatous hamartoma (EAH), an uncommon tumor that may present variable clinical and histological features. In addition, this particular case exhibited a prominent component of arterio‐venous malformation that distinguishes it from other EAHs described in the literature and adds to the spectrum of histologic findings that can be seen with this entity.
