A fatal case of multicentric Castleman's disease (giant lymph node hyperplasia) with prominent thymic involvement in a 12-yr-old girl is presented. Multicentric Castleman's disease is a poorly understood lymphoproliferative disorder generally occurring in elderly individuals. ⋯ Besides the characteristic findings of Castleman's disease (CD), such as hyaline-vascular follicles and a prominent plasmacytic infiltrate, the thymus was also marked by prominent epithelial hyperplasia in the medulla. The clinical and pathologic findings are presented with a review of the literature, particularly thymic involvement in CD and CD in the pediatric population.
