An autochthonous case of paracoccidioidomycosis was reported in a city of north Iran. This condition is a well-known endemic fungal infection highly prevalent in Latin American countries, with an incidence of 1 to 3.7 cases per 100.000 annually in Brazil. The classical features are cutaneous lesions, lymph node, and pulmonary involvements, while typical oral changes are superficial ulcers with hemorrhage and moriform aspect. Herein is reported an adult male patient with characteristic oral and pulmonary lesions. Rural environment, male gender, cigarette smoking, and alcohol abuse were risk factors; and clinical history, imaging studies, and histopathologic data established the diagnosis. The patient improved well by administration of sulfamethoxazole plus trimethoprim. The aim of this case study is to enhance the awareness of generalists about this mycosis.
