ABSTRACT
The oto-rhino-laryngologic presentation forms of paracoccidioidomycosis are frequent. Periodontal lesions also occur in a large number of cases, especially in patients from rural zones usually having no access to primary dental care. The first published cases of paracoccidioidomycosis exhibited lesions of the mouth, tongue, and larynx which were described as primary. The differential diagnosis of buccopharyngeal lesions will have to be made with tegumentary leishmaniasis, tuberculosis, syphilis, and neoplastic processes. The ulcerated lesion can be located on the inner surface of the lips, cheeks, palatine velum, or tongue, showing granulations of varying types arranged in a saw-toothed pattern. Papillomatous or verrucous lesions can occur near the vestibule of the larynx, close to the epiglottis, exhibiting circinate borders. Malignant tumoral lesions, such as epidermoid carcinoma, vary in terms of gross findings. They are located on the lips, cheeks, mouth floor, tongue, tonsil pillars, pharynx, and larynx.
