A rare form of isolated mesenteric Castleman's disease presenting as an abdominal mass (isolated mesenteric Castleman's disease).

Castleman's disease is a rare disorder characterized by proliferation of the lymphoid tissue. The most frequent location of the disease is the mediastinum. The location of the disease in the mesentery is rare and it is usually associated with the generalized form of the disease. We report a case of a 22-year old woman with isolated mesenteric Castleman's disease of the lymphoid variant, which presented as a palpable abdominal mass. The final diagnosis was reached after exploratory laparotomy and resection of the tumor. The described case is the first reported case of Castleman's disease of the lymphoid subtype, located in the mesentery.
