Primary laryngeal tuberculosis (PLT) is a granulomatous infection of the larynx caused by Mycobacterium tuberculosis without affecting the lungs. It is a rare type of extrapulmonary tuberculosis seen in clinical practice. After the introduction of antitubercular therapy (ATT), the incidence of LT is reduced and remains stable. However, the incidence of PLT is increasing due to acquired immune deficiency syndrome epidemic. The important clinical presentations of PLT are dysphonia and odynophagia. The diagnosis is confirmed by histopathological examination as it often mimics laryngeal malignancy. The treatment is ATT, whereas surgery is only reserved in certain situations where is compromising the laryngeal airway by its granulomatous growth. Delayed or misdiagnosis or untreatable LT will lead to high morbidity and mortality of a patient. Although primary tubercular lesion has nonspecific clinical presentations, it is very important to have a high index of suspicions to rule out tubercular lesion in the larynx as this disease is a curable one.
