The latter occurs in the central and northern regions of Brazil. The differentiation of species is only possible with molecular methods currently available in research centers, but the region of the country can be indicative of a species. Both species of Paracoccidioidesdetected so far are causative agents of PCM. Oral manifestations of PCM are strongly related to gingival involvement.
