Mesenteric Castleman's disease: report of a case and literature review.

Castleman's disease is a rare benign lymphoproliferative disorder which most occurred in mediastinum. There are three subtypes of Castleman's disease. The hyaline-vascular variant is often localized, asymptomatic, and with benign outcome. Whereas the plasma cell and multicentric variants are systemic diseases frequently associated with HIV infection or other hematopoietic malignancies. Mesenteric Castleman's disease is extremely rare. Less than 30 cases have been reported. Here, we report a case of mesenteric Castleman's disease with initial gastrointestinal symptoms.
