A rare case of Kikuchi-Fujimoto disease

Kikuchi-Fujimoto disease, characterized by histiocytic necrotizing lymphadenitis, closely mimics tuberculosis, and lymphoma are two most common etiologies of cervical lymphadenitis. It is a rare, benign, and self-limited disease. Viral infections or autoimmunity are hypothesized as its etiology, but no causal relationship is definitely established till date. No specific treatment is available, only supportive treatment is given. Here, we represent a rare case of Kikuchi's disease in a 29-year-old male patient who presented to us with right-sided posterior cervical lymphadenopathy with low-grade fever for three months.
