RESUMO
Angiolymphoid hyperplasia with eosinophilia is a rare disease characterized by vascular proliferation of unknown origin. The lesions are mostly seen in the head and neck region and are characterized by papules or nodules. A 20-year-old man presented with a 1 year history of reddish papulo-nodular lesions overlying a pulsatile swelling on the left auricular area. Histopathology was suggestive of angiolymphoid hyperplasia with eosinophilia. B-mode ultrasonography, color Doppler and angiography revealed arterial ectasia and arteriovenous malformation of the left auricular artery. Such malformations have been reported previously, in association with angiolymphoid hyperplasia with eosinophilia. The cutaneous lesions responded well to transarterial embolization of the nidus.
