In para-clinical findings ESR=50mm/hr Hb= 10gr/dl. WBC count was 5300/microl bone marrow aspiration and biopsy with lymph node was done. The histopathologic diagnosis was Kikuchi Fujimoto [Necritizing Lymphadenitis]. The second patient was a lady with 35 years old and painful neck mass [behind the sterno-clido mastiod] from 1.5-month age with fever and chill. In paraclinical findings ESR=52 mm/hr WBC 5500/microl, CRP++ lymph node biopsy was done the histopathologic diagnosis was Kikuchi Fujimoto Necrotizing Lymphadenitis.
