Kikuchi-Fujimoto disease (KFD), also referred to as histiocytic necrotizing lymphadenitis, is an uncommon entity, usually benign, self-limiting disease characterised by fever and regional lymphadenopathy of unexplained aetiology. There is an increase in reported cases of KFD, particularly in Asia. It is important to recognize this condition because it may be confused for systemic lupus erythematosus (SLE), tuberculosis or lymphoma. The knowledge of this condition among clinicians and pathologists can help to avoid misdiagnosis and inappropriate treatment. It must be considered among the differential diagnoses of cervical lymphadenopathy. Here, we present a case of 20-year-old male who came to the hospital with complaints of mild fever, chills, fatigue and cervical lymphadenopathy. After radiological investigations an excisional biopsy of the cervical lymph node was done and the diagnosis of KFD was confirmed. Due to the paucity of cases in literature, reporting this case may help shed light on this rare disease.
