Chronic Large Non Healing Ulcer: Non-Tuberculous Mycobacterial Infection of the Laryngopharynx.

We describe a case of non-tuberculous mycobacterial infection of the larynx in a previously well, immunocompetent young woman. Laryngeal mycobacterial infection is rare and currently accounts for less than 1% of all cases. A diagnostic dilemma often occurs because it may mimic laryngeal carcinoma, chronic laryngitis, or laryngeal candidiasis. This case highlights the importance of considering non-tuberculous mycobacterial infection in the differential diagnosis of laryngeal lesions.
