Primary laryngeal histoplasmosis: a case report

Abstract

BackgroundHistoplasmosis is a fungal infection that commonly occurs in the lungs or in disseminated form. Primary laryngeal histoplasmosis is a very rare condition that can mimic laryngeal carcinoma or laryngeal tuberculosis. The purpose of this case report is to highlight the rare occurrence of primary laryngeal histoplasmosis with no involvement of other organs, especially the lungs, the diagnosis dilemma, and the antifungal protocol for this case.Case presentationWe report a case of a 47-year-old male, who is a pigeon breeder, presented with chronic hoarseness. There were no signs of pulmonary or systemic involvement. Biopsy from laryngeal mucosa was confirmed as histoplasmosis, and he was started on intravenous (IV) amphotericin B for 2 weeks and oral itraconazole for 2 months.ConclusionPrimary laryngeal histoplasmosis is considered a very rare occurrence. The laryngeal lesion may mimic conditions such as laryngeal carcinoma and laryngeal tuberculosis. Histopathology examination remains the gold standard, and antifungal treatment is the choice of therapy.
