External Ear Arteriovenous Malformation
Arteriovenous malformations (AVM) of the external ear are relatively uncommon lesions. They typically present during childhood. Some of them may remain quiescent until adolescence and in some cases into adulthood. Enlargement of the AVM may be triggered by trauma, infection, or hormonal influences (1). We report herein a unique case of spontaneous AVM of the external ear clinically revealed in the third decade of life, which is a very rare condition.
