Castleman disease: a case with atypical presentation.

Castleman disease is a benign lymphoproliferative disorder characterized by enlarged lymph nodes. In children the disease is rare, usually localized, and asymptomatic. Resection of the node is almost always curative. A case is reported that was diagnosed as hyaline vascular-type Castleman disease at 1 year of age. The disease recurred from infraclavicular region in addition to primary site, even though total excision was performed. Although the disease is mullticentric after recurrence, the patient has no systemic symptoms.
