Kikuchi-Fujimoto disease: a report of 3 cases.

Cervical lymphadenopathy has many underlying etiologies. One of its rare causes is Kikuchi-Fujimoto disease (Kikuchi's disease, histiocytic necrotizing lymphadenitis). We discovered such a cause in a 37-year-old woman who had presented with malaise, night sweats, and weight loss in addition to cervical lymphadenopathy.
