Abstract
Pemphigus comprises a group of autoimmune bullous diseases, which have a tendency of progression, with unlimited and chronic development and with a potentially to fatal disease prognosis. The most common type is the Endemic Pemphigus Foliaceus (EPF), characterized by the presence of skin lesions with blistering located on the face, scalp and interscapular region. Environmental, genetic and immunological factors may trigger the disease. Among the environmental factors, exposure to mercury, mineral dust and Simulium nigrimanum mosquitoes bite should be considered. Sought to, in this article, it is reported the occurrence of PFE among the population of Antonio Pereira, rural district of Ouro Preto, Minas Gerais, and identify their possible association with occupational and environmental local factors. A prevalence of 4.57 cases of EPF/1.000 inhabitants, considered high was found. There was association between the disease and contact with dam tailings mining (p=0.048); and exposure to mercury (p=0.008). The results indicate the need for effective surveillance of the affected communities, as well as adequate health care of patients affected by the disease.
