Herein, we present the case report of an adult male diabetic patient who had coinfection with Mycobacterium tuberculosis and mucormycosis, which otherwise is a rare clinical entity. Diabetes mellitus may predispose a patient to tuberculosis (TB) infection which further weakens immune system thus making him susceptible to other fungal or bacterial infections which may pose various treatment difficulties. Therefore, there is a need for mycological and bacteriological investigations in patients with pulmonary TB to rule out secondary coinfections thus contributing to better management.
