title: Squamous cell carcinoma arising from an arteriovenous malformation of the scalp.
abstract: We present the case of a 70-year-old man with a congenital scalp lesion consistent with an arteriovenous malformation (AVM) which over the last 3 years had developed ulcerative changes and bleeding in the central aspect that was a biopsy proven squamous cell carcinoma (SCCA). To control hemorrhage during surgery, a radiologist performed selective embolization of major feeding arteries in the lesion three days before the surgery. After total resection of the lesion, a scalp reconstruction was performed by using a free latissimus muscle flap and skin graft. As a result, bleeding was well controlled, the AVM and SCCA were totally resected, and satisfactory aesthetic results were obtained. This appears to be the first description of a SCCA arising from a chronic AVM. This is suggestive of a possible Marjolin's ulcer from a chronic wound bed.
