title: Castleman's disease of the left triceps in a child suspected to be a small round cell tumor of childhood.
abstract: Castleman's disease (CD) is histologically characterized by a proliferation of polyclonal small lymphocytes and plasma cells. The clinical presentation varies widely, but most commonly manifests as a solitary mediastinal mass, incidentally found on radiographic examination. We present a case of a 10-year-old girl who exhibited a left arm mass which, preoperatively and on frozen section, was diagnosed as a small round cell tumor of childhood (SRCT). This report emphasizes the unusual location of CD in the soft tissue and as a rare entity to be considered in the differential diagnosis of SRCT.
