Unusual Presentation of Extrapulmonary Tuberculosis as Laryngeal Mass in an Atypical Patient.

Abstract

Spread of Mycobacterium tuberculosis (MTB) to the larynx is exceedingly rare and can be obscured by more common conditions such as laryngeal cancer or oropharyngeal candidiasis, complicating an accurate diagnosis. Risk factors for chronic laryngeal disease, such as smoking and toxin exposure, place TB infection comparatively lower for consideration on a physician's differential. However, identifying these lesions is crucial from a medical and public health perspective to prevent community spread. We report the case of a 60-year-old male who presented with dysphonia, pharyngitis, aphasia, and significant unintentional weight loss. X-rays demonstrated focal opacities in the upper lung lobes. Laryngoscope biopsy revealed caseating granulomas and a positive culture for MTB. Laryngeal TB presents as a suspicious throat mass with nonspecific symptoms and should be thoroughly investigated by clinicians.
