[Kikuchi-Fujimoto's disease: Report of 4 cases and literature review].

Introduction: Kikuchi-Fujimoto's disease or histiocytic necrotizing lymphadenitis is a benign disease predominantly occurring in young women which etiology remains unknown and revealed by cervical lymphadenitis and/or prolonged fever.

Observations: This report describes a survey of four patients who developed Kikuchi's lymphadenitis occurring concomitantly with LES in one case and actinomycosis in another case. The definite diagnosis is usually made through histopathological examination of a lymph node biopsy. The evolution was favorable under corticosteroid therapy in two patients, antibiotics in the third and only antipyretic in the fourth.

Conclusion: The authors bring report through these three observations, the diagnostic difficulties, the therapeutic means of the disease of Kikuchi, as well as its evolutionary aspects.
