[Kikuchi-Fujimoto's disease: report of 5 cases and literature review]

Abstract

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. It has rarely been reported in children. Among the 5 cases reported, 1 child had a systemic localization. The diagnosis is based on the histological examination of a lymph node biopsy. The disease course was spontaneously favourable in 2 cases; a corticotherapy was needed in 3 children. A pathogen agent was found in 2 patients. Kikuchi's disease can reveal or evolve into autoimmune disease particularly lupus, thus a long clinical and biological follow-up is necessary.
