Isolated laryngeal tuberculosis: A diagnostic dilemma

INTRODUCTION AND IMPORTANCE: Primary laryngeal tuberculosis (PLTB) is a rare condition. The symptoms and findings are not specific in most of the cases. Patients are diagnosed essentially based on histopathological examination and mycobacterial culture. CASE REPORT: We report the case of a 42-year-old woman who presented to our hospital with dysphonia and dysphagia. Direct laryngoscopy revealed a lesion of the supraglottis. CT scan found a diffuse thickening of the entire surface of the larynx. A biopsy confirmed the diagnosis of tuberculosis. CLINICAL DISCUSSION: Primary laryngeal tuberculosis is a rare clinical entity despite its close anatomical and physiological proximity to the lungs. CONCLUSION: Clinician should keep in mind the existence of primary laryngeal tuberculosis to avoid delayed diagnosis and treatment, which can lead to high morbidity and mortality.
