Abstract:
Laryngeal histoplasmosis is a very rare cause of laryngitis which is encountered usually in the immunosuppressed states but can also occur in immunologically intact status. We report a rare case of laryngeal histoplasmosis in a man in his 60s, a chronic smoker who presented with a history of progressive hoarseness for 3 months. The glottic growth was biopsied. The rarity of diagnosis was aided by histopathological examination of the tissue, which revealed histoplasmosis. Management was done with intravenous liposomal amphotericin B and oral itraconazole with complete resolution of symptoms.
