[Kikuchi's necrotizing lymphadenitis. Clinical and pathological study of a new case]

Contribution to the topic with the case of a woman, 24, admitted in our ENT Department for exam and treatment of multiple right sided adenopathies of the neck. The histopathological study was consistent with diagnosis of Kikuchi's necrotizing lymphadenitis. This is a new clinicopathologic entity first described, 1972, by Kikuchi, of unknown etiology, an a picture characterized for painful cervical lymphadenitis presented in young women and healing spontaneously after 2-3 months course. We want to emphasize in this paper the scarcity of cases published and the difficulties arising when dealing with the differential diagnosis with lympho-proliferative malignancies as well.
