AN ANGIOSTATIC AGENT IN TREATMENT OF A RECURRENT ANEURYSMAL BONE-CYST

Healing of an aggressive recurrent aneurysmal bone cyst of the distal humerus was induced by oral dexamethasone, an angiostatic agent. The s evere pain and tenderness resolved rapidly. The soft tissue swelling s ubsided, and a thick layer of bone formed around the cyst. Complete he aling followed saucerization and curettage of the remaining vascular t issue in the center of the cyst. We suggest that angiostatic agents be included in the nonoperative methods of treatment of aggressive aneur ysmal bone cysts.
