    Abstract:
    Histoplasma capsulatum is an endemic granulomatous fungus disease. Involving the larynx of an immunocompetent patient with this is a rare manifestation. A sixty years old farmer who was previously diagnosed and treated as pulmonary tuberculosis was presented as a progressive change of voice and intermittent attack of unproductive cough with no history of stridor and fever for last 7 months. Clinical and imaging investigations were suggestive of laryngeal tuberculosis or laryngeal neoplasm. Laryngoscopy revealed edema, erythema and leukoplakia of the right vocal cord. Histopathological report showed intracellular hyphae of Histoplasma capsulatum, features were consistent with histoplasmosis. Patient were treated accordingly and improved. Laryngeal histoplasmosis present as a mimicker of squamous cell carcinoma or tuberculosis, may lead to the misdiagnosis and mistreatment of tuberculosis or laryngeal cancer. A high index of suspicion and a thorough histologic workup is needed to establish the diagnosis correctly.
