Primary laryngeal leishmaniasis: A rare case report

Abstract

Laryngeal leishmaniasis is extremely rare. We report a case of primary laryngeal leishmaniasis in a 70-year-old male who was admitted with complaints of gradual progressive hoarseness of the voice, dyspnea, cough for the past 3 months and noisy breathing for the past 5 days. An X-ray of the soft tissue of the neck showed a prevertebral soft tissue mass causing narrowing of the airway at the C6-C7 vertebral level. A computerized tomography (CT) scan showed a soft tissue mass in the subglottic region causing significant narrowing of the airway. A direct laryngoscopy showed a pinkish-white, friable mass involving the subglottic region and the anterior half of the vocal cords. With the clinical suspicion of malignancy, an endoscopic biopsy was done. A histopathological examination showed diffuse mixed inflammatory cell infiltrate in subepithelium with numerous Leishmania donovani bodies in the cytoplasm of histiocytes.
