Lymphadenopathy can be caused by localized and systemic diseases. While viral and bacterial infections commonly cause lymphadenitis in young adults, tuberculosis (TB) is a common cause for lymphadenopathy in endemic areas. Besides, lymphadenopathy may be a presenting manifestation of malignancy, systemic disorders and some rare diseases. Thus, relevant evaluation and exclusion of commoner causes is important to clinch the diagnosis. Histopathological examination is mandatory in such patients. We hereby report the case of a young adult male who presented with low-grade fever and abdominal pain with cervical and mesenteric lymphadenopathy in a TB endemic region, but was proved to have atypical presentation of Kikuchi–Fujimoto disease, which is a rare but benign cause of lymphadenopathy.
