Localized early mesenteric Castleman's disease presenting as recurrent intestinal obstruction: a case report.

Primary neoplasms of the mesentery are very rare. They are usually of mesenchymal origin and include desmoid tumor, lipoma, liposarcoma, and fibrosarcoma. Metastatic carcinomas and lymphoma are more common. We report a rare case of localized mesenteric Castleman's disease, presenting as intestinal obstruction. Clinical and radiological findings were suspicious for lymphoma. Localized mesenteric Castleman's disease, though rare, has to be considered in the differential diagnosis of mesenteric tumors, particularly in the young and in the absence of history for other tumor, an abnormal blood picture, or splenomegaly.
