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.
