Between 1982 and 1986 we have had the chance to study 21 patients with pemphigus foliaceus of the 'fogo selvagem' type. The patients came from El Bagre and Nechi, rural areas of Colombia with some gold mining. This is the first outbreak of South American pemphigus foliaceus reported in Colombia. The majority of the patients were mestizo men, who worked as farmers or miners or both, with an average age of 44. Five patients were relatives. Eleven patients (52%) had mild disease, three (14%) moderate disease and seven (33%) severe disease. During hospitalization, three patients died due to complications or as a result of immunosuppressive treatment. Of the remaining 18 patients, 10 were in remission with treatment, one was in remission without treatment, while no information was available on the remaining seven.
