Treatment of skin necrosis after radiation synovectomy with yttrium-90: a case report.

Chronic synovitis, unresponsive to systemic medical therapy including agents, anti-inflammatory drugs and remission-inducing agents, and intra-articular administration of corticosteroids can be treated with surgical, chemical and radiation synovectomy. We reported a case of a 23 years old male. Skin radiation necrosis (4 x 5 cm) developed after an injection of Yttrium-90 (Y-90). Full-thickness skin graft had been applied but we were not able to succeed. Skin radiation necrosis was treated with Limberg's flap. As a result we recommend flap surgery instead of skin graft in skin radiation necrosis.
