[Pronunciation]
[Benjamin Castleman, U.S. pathologist, 1906–1982]
An occasionally aggressive illness marked by excessive growth of lymphoid tissue either localized in a single lymph node group or in multiple regions of the body.
Although the cause is not precisely known, its associations with acquired immunodeficiency syndrome, Kaposi's sarcoma, and human herpes virus 8 infection have led some experts to propose that it has an infectious basis. Localized disease responds well to surgical resection. Widespread disease can sometimes be treated effectively with chemotherapy.
