Necrotizing Histiocytic Lymphadenitis: Report of two cases (Kikuchi-Fujimoto disease)

Abstract

Kikuchi-Fujimoto disease is a necrotizing Lymphadenitis with benign self-limit process in young women with fever, cervical lymphadenopathy and increased ESR with leukopenia. In this report we introduce 2 females with Kikuchi-Fujimoto disease. The first patient was a 31 years old lady with fever and unilateral cervical lymphadenopathy weight loss from 20 days age. In paraclinical findings ESR=50 mm/hr Hb=10 gr/dl. WBC count was 5300/µl bone marrow aspiration and biopsy with lymph node was done. The histopathologic diagnosis was Kikuchi-Fujimoto (Necrotizing Lymphadenitis). The 2nd patient was a lady with 35 years old and painful neck mass (Behind the sterno-clido mastoid) from 1.5-month age with fever and chill. In paraclinical findings ESR=52 mm/hr WBC 5500/µl, CRP++ lymph node biopsy was done the histopathologic diagnosis was Kikuchi-Fujimoto necrotizing Lymphadenitis. Therefore Kikuchi disease is a important differential diagnosis in young patients especially women with cervical lymphadenopathy and fever (FUO).
