Paracoccidioidomycosis is a systemic mycosis caused by dimorphic fungus of the complex Paracoccidioides brasiliensis, which is found in soil and in a variety of animals, and transmitted to humans by inhalation. It is restricted geographically to Central and South America, where it is the commonest endemic chronic human mycosis, acquired in rural and periurban areas, equally distributed among prepubescent boys and girls, but more frequent in men than women (10:1)....
