Kikuchi lymphadenitis: A differential diagnosis of tuberculous cervical lymphadenitis

Abstract

Patients from countries, endemic with tuberculosis, who present with febrile lymphadenopathy refractory to first line antibiotics are often empirically treated for extra-pulmonary tuberculosis. However, Kikuchi-Fujimoto Disease (KFD) or histiocytic necrotizing lymphadenitis, a self-limiting and benign condition, presents with similar clinical symptoms. We present an adolescent with febrile lymphadenopathy, who was initially treated for tubercular lymphadenopathy, before a diagnosis of KFD was made.
