Aneurysmal bone cyst of the rib: a case report.

Introduction: An aneurysmal bone cyst is a benign, but expansile tumor like lesion that generally occurs in the long bones including the vertebral column. An aneurysmal bone cyst arising from the rib, especially in the elderly, is extremely rare. Case presentation: We report a 58-year-old Turkish woman with an aneurysmal bone cyst of the right 3rd rib treated with chest wall resection. The pathologic findings confirmed the diagnosis of aneurysmal bone cyst. The patient has been followed up for 5 years with no evidence of recurrence. Conclusion: En bloc resection can be curative and provide good results for this rare type of chest wall tumor.
