Laryngeal Tuberculosis Revealed by Laryngeal Dyspnea

Isolated laryngeal tuberculosis is rare, it can be considered as a malignant tumor which delay the diagnosis and worsens the prognosis. We report the case of a 31-years-old patient admitted to the emergency room for the management of a progressive laryngeal dyspnea, with a laryngoscopic examination confirmed an erythematous and thick appearance of the two vocal cords. The histological examination revealed epitheloid and giganto-cellular granulomas with a caseous necrosis suggestive of tuberculosis. Culture on lowenstein medium of tissue biopsied from the vocal cords was positive. No other tuberculosis localization was found. The patient underwent standard antituberculosis therapy (isoniazid, rifampicin, ethambutol, pyrazinamide), which completely resolved the clinical situation.
