A white man with Kikuchi-Fujimoto disease mimicking lymphoma, preceded by frequent episodes of tonsillitis: a case report

Background Kikuchi-Fujimoto disease is a very rare cause of benign lymphadenopathy affecting mainly young Asiatic females. Little is known about the causative agent of Kikuchi-Fujimoto disease; however, there are hypotheses of infectious, autoimmune, or hyperimmune background of the disease that have not yet been confirmed in the conducted studies. Frequent episodes of tonsillitis preceding the onset of Kikuchi-Fujimoto disease have not been described as yet.
