Abstract: | Histoplasmosis is a rare systemic fungal infection, primarily affecting the pulmonary system. Oral lesions are usually a manifestation of the disseminated form of the disease and most frequently observed in severely immunocompromised patients, such as those with advanced human immunodeficiency virus infection and/or frank acquired immune deficiency syndrome. The clinical presentation of the oral lesions may be difficult to distinguish from oral squamous cell carcinoma. The histopathological features are usually characteristic, but occasionally the organisms are scanty and not readily identified, which can preclude obtaining the correct diagnosis and ensuring appropriate management. Histoplasmosis is an unusual and rare cause of chronic non‐healing ulceration in the oral cavity. A case of histoplasmosis involving the oral cavity in an immunocompetent patient is reported, which was not recognized, resulting in the inappropriate management of the condition. |
