Kikuchi-Fujimoto Disease With Isolated Mediastinal Lymphadenopathy: A Rare Presentation of an Even Rarer Disease.

Kikuchi-Fujimoto disease (KFD) is a rare self-limiting condition presenting as fever and cervical lymphadenopathy, with only two reported cases with isolated mediastinal lymphadenopathy. Lack of awareness about this condition often results in a high rate of misdiagnosis. We present a case of a 29-year-old Indian male with fever, mucocutaneous ulcers, weight loss, and mediastinal lymphadenopathy on CT.
