[Histoplasmosis in the northeast of Brazil. Report of three cases].

Histoplasmosis is an endemic mycosis in specific areas of the U.S. and Latin America, caused by dimorphic geophilic fungus H. capsulatum. The description of cases in Brazil's northeast, considering that this region isn't an endemic area, indicates the existence of small outbreaks in several regions. Precise reasons for this pattern of distribution are still unknown. Activities related to the removal of soil in these places are associated with exposure to H. capsulatum. The objective of this work is to describe three isolated cases of histoplasmosis which occurred in Brazil's northeast region in individuals exposed to different activities (demolition of houses, wells diggers and exposure to bats).
