Unique Oral Presentations of Deep Fungal Infections: A Report of Four Cases.

Deep fungal infections rarely involve the oral cavity and most commonly affect immunocompromised patients. Oral deep fungal infections typically manifest as chronic mucosal ulcerations or granular soft tissue overgrowths. Since these lesions are non-specific and can mimic malignancy, it is crucial to obtain a thorough clinical history and an adequate biopsy to render the appropriate diagnosis. We report four new cases of deep fungal infections, diagnosed as histoplasmosis, blastomycosis and chromoblastomycosis, exhibiting unique oral and perioral presentations. Awareness of these unusual entities can help dental and medical practitioners expedite proper multidisciplinary care and minimize morbidity and mortality.
