Abstract
Paracoccidioidomycosis, a deep infection caused by the dimorphic fungus, Paracoccidioides brasiliensis, occurs endemically in different rural areas of Brazil. Late diagnosis or poorly conducted treatment can result in death, emphasizing the importance of a rapid and accurate diagnosis and correct treatment. The authors report 2 cases, the first involving a 40-year-old Caucasian man, a smoker for more than 10 years, presenting with ulcerated lesions, with raised borders, of approximately 4 cm, with 30 days of evolution, in the anterior third of the tongue, which did not heal; the second, a 22-year-old Caucasian woman, with lesions on the bilateral soft palate, with an evolution of 2 months. The initial diagnoses for both the cases were pemphigus and lichen planus. Reports of incisional biopsies of both the patients indicated paracoccidioidomycosis. The patients were referred to the infectology service for systemic evaluation and treatment. Currently, they are free of the disease.
