Multicentric Castleman's disease in a child with prominent thymic involvement: a case report and brief review of the literature.
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. To our knowledge, this is the first case in the English literature of multicentric Castleman's disease in a child. Thymic involvement has not been described previously in the multicentric variant or in a child. 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.
