title: The heterogeneity of Castleman disease: report of five cases and review of the literature.
abstract: Castleman disease (CD; angiofollicular lymphoid hyperplasia) is a heterogeneous group of lymphoproliferative disorders of uncertain cause. Three histologic variants (hyaline vascular, plasma cell, and mixed) and two clinical types (localized and multicentric) of CD have been described. We report 5 cases of CD treated in our institute and review the literature about the management of this relatively rare disorder. Localized and multicentric CD may be different clinical disorders with overlapping histologic features. Localized disease generally presented with a single enlarged lymph node or widening of the mediastinum, whereas multicentric disease is a systemic lymphoproliferative disorder characterized by lymphadenopathy, hepatosplenomegaly, constitutional symptoms, anemia, hypoalbuminemia, and hypergammaglobulinemia. Unlike the localized type, for which surgical excision is curative regardless of the histologic type, multicentric disease often necessitates aggressive systemic therapy and portends a poorer outcome.
