[Kikuchi-Fujimoto disease: report of two cases]

Kikuchi-Fujimoto disease, described for the first time in 1972, is an unusual diagnosis that is characterized by lymph node enlargement and fever. Cervical lymph nodes are affected so often that ENT specialists should be aware of this entity during differential diagnosis. The diagnosis was done by histological features, necrotizing lymphadenitis. The disease is self-limited and it has good prognosis. We have reviewed two cases in our hospital. We report an aseptic meningoencephalitis as a rare complication.
