Castleman's disease of the chest wall.

Primary Castleman's disease of the chest wall is unusual. Furthermore, such tumors arising from a surgical wound are extremely rare. We report a 33-year-old female with a history of a thoracic surgery at 5 years of age. A round, homogenous 4 x 3.5-cm mass protruded into the thoracic cavity on the posterior portion of the previous posterolateral incision. The tumor was completely removed, with combined rib resection. The resected specimen showed Angiofollicular Lymph Node Hyperplasia (Castleman's disease), hyaline-vascular type. No recurrence has been found for 10 years. This is the first report of primary chest wall Castleman's disease arising from the surgical wound.
