Kikuchi-Fujimoto Disease: A Diagnostic Dilemma

Kikuchi- Fujimoto disease (KFD), is one among the rarest diseases amongst the Asian population. It is characterized by fever and sub acute necrotic lymphadenopathy. Commonly seen in young adults but occurs in older age groups also. Cervical lymph nodes are frequently involved. Pathogenesis of the disease is still uncertain. Diagnosis is based on histopathological examination. Differential diagnosis includes infections like tuberculosis, syphilis, infectious mononucleosis, cat scratch disease, autoimmune disease like systemic lupus erythematosus to malignancies like lymphomas. The disease is self limiting with a benign course hence observation is the best way to manage. Minor dosage of antipyretic would provide supportive therapy to the patient.
