The Association of Mycobacterium tuberculosis with Kikuchi Syndrome: A Case Report and Literature Review

Kikuchi-Fujimoto disease (KFD) is considered one of the rare benign conditions of unknown etiology presenting with the triad of cervical lymphadenopathy, fever, and weight loss. The inciting cause continues to be elusive. One of the leading thoughts is that it may be a post-infectious immune response of T-cells and histocytes. The most common triggers reported have been viral infections. Treatment mainly revolves around the reduction of the inflammatory response with anti-inflammatory medication and steroids when appropriate. To date, there are very limited reports of Mycobacterium tuberculosis as an inciting agent documented. Here, we present a rare case of Kikuchi-Fujimoto disease following Mycobacterium tuberculosis infection, more than four years after the completion of therapy.
