A 40-year-old caucasian man presented with a symptomaic large ulcer in his tongue, with a granular purpuric surface, which appeared three months before admission to the out- paient clinic. He also complained of weight loss, fever and anorexia. The paient has been a smoker and an alcohol addict for 25 years. No producive cough was observed and a chest x-ray did not show areas of nodular iniltraion. Intraoral examinaion showed evidence of an ulcer, in the form of mulberry-like granulomatous lesions on the border of the tongue measuring about 4.0cm (Figure A). Also, a gingival linear erythema dispersed in the maxilla was ideniied and bone lesions in the jaws were not evident.

The diagnosic hypothesis was squamous cell carcinoma. An exfoliaive cytology and incisional biopsy were performed. The main morphological indings in the cytological exam were the presence of spherullous, birefringent, and muliple-budded fungi (Paracoccidioides brasiliensis), surrounded by Langhan’s giant cells, epithelioid cells, and nonspeciic inlammatory cells (Figure B). Biopsy specimens completed the cytological evaluation and showed granuloma formaions with mulinucleated giant cells and a polymorphonuclear with vacuoles suggesive of infecion (Figure C). The diagnosis was oral paracoccidioidomycosis. The treatment was performed with itraconazole 300mg daily for 12 months. In 24-month follow-up, there is no evidence of disease.

This report emphasize that physicians must realize the possibility of paracoccidioidomycosis and squamous cell carcinoma at this risk populaion. In this sense, some speciic characterisics of the diagnosis process could help to idenify both lesions.

consumo de álcool por 25 anos. Não foi observada tosse produiva e uma radiograia de tórax não apresentou área de iniltração nodular. O exame intraoral evidenciou úlcera granulomatosa com aspecto moriforme em borda de língua, medindo cerca de 4,0cm (Figura A). Além disso, eritema gengival linear disperso na maxila foi ideniicado e lesões ósseas nos maxilares não eram evidentes.

A hipótese diagnósica foi de carcinoma de células escamosas. Uma citologia esfoliativa e biópsia incisional foram realizadas. Os principais achados morfológicos no exame citológico foram a presença de fungos birrefringentes com múliplos brotamentos e formato esférico (Paracoccidioides brasiliensis), envolvidos por células gigantes ipo Langhans, células epitelioides e células inlamatórias inespecíicas (Figura B). A biópsia concluiu a avaliação citológica e mostrou formação de granulomas com células gigantes mulinucleadas e polimorfonucleares com vacúolos sugesivos de infecção (Figura C). O paciente recebeu 300mg de itraconazol por dia durante 12 meses. Os 24 meses de acompanhamento forneceram evidências de que a doença fora curada.
