Arteriovenous malformation (AVM) results from errors in vascular development during embryogenesis; absent capillary beds lead to shunting directly from the arterial to venous circulation. Although it is common in the head and neck region, Arteriovenous malformations (AVM) of the external ear are relatively uncommon lesions. They typically present during childhood. We report a case of giant AVM of the right pinna in 8 years child, which are very rarely seen. We discussing the definition, clinical findings, diagnostic approaches of arteriovenous malformations.
