Arteriovenous hemangiomas (AVH) are acquired benign vascular lesions comprising interconnecting arterial and venous structures. These lesions result from the aberrant development of vascular elements in capillaries, arteries, and veins.1  Angiogenic factors have been isolated and play a role in AVH pathogenesis.2 AVH are compressible and do not spontaneously involute. Unlike the deeper variety that predominates in children and adolescents, superficial lesions most commonly affect middle-aged and elderly adults and are frequently found on the head and neck.3

Diagnosis is made clinically and may be aided by dermoscopy, which characteristically reveals nonarborizing telangiectasia and homogeneous pigmentation.4 Histopathology reveals arteries and veins in proximity to each other. Shave excision with cautery and laser ablation is curative.
