Castleman's lymphoadenopathy: twenty years of observation. I. General considerations. Monodenopathic variety

After a short review of the nosologic definition of Castleman's lymphadenopathy in its monoadenopathic form, the authors describe five cases of this rare condition of lymphatic tissues, personally observed over a period of 17 years. The authors try to evaluate the different pathogenetic hypotheses proposed in the last years. In their opinion the process falls ito the group of autonomous proliferations. A subsequent paper will treat the systemic form of Castleman's lymphadenopathy.
