In that revision, the author concluded that tegumentary leishmaniasis (TL) already existed in the country for many years and distinguished three stages in the historical development of the disease. The first one, of uncertain origin and based on vague references, extended until 1895, the year that was marked by the clinical observation of Bahia button and its relationship with the Oriental button. The second stage extended until 1909, when the etiologi- cal agent of Bauru ulcer was identified and described. The third stage started in 1910, when the parasite was found in mucosal lesions, then added to the clinical picture of the disease, and went up to the publication of the article. Archeological studies developed in Peruvian huacos - ceramic vases displaying reproduction of human images, both healthy and disease-mutilated ones - could assure the occurrence of uta and espundia - local names for the cutaneous and mucosal forms of TL, respectively - among the Incas, during the pre-Colombian era, although they were misinterpreted as syphilis in the beginning. On the other hand, studies of anthropomorphic ceramics produced by our Indian ancestors, due to their rudimentary characteristics, did not enable the same type of observation. The only safe and probably older indication of the disease in Brazil is found in a citation contained in the thesis by Tello, Antiguedad de la syphilis en el Peru, of 1908 and related to the written work Pastoral Religioso- Politico Geographico, published in 1827 and repor- ting a missionary's trip in the Amazon region. The missionary observed individuals presenting ulcers in their arms and legs, related to insect bites, which resulted in destructive lesions in their mouth and nose. Since it had not been previously mentioned in Brazil, Rabello thought it was more reasonable to suppose that, being endemic in the Amazon region, but at the same time originated from Peru and Bolivia, the disease could have spread in the Northern states in Brazil by individuals who trave- led to that area looking for work at the rubber tree exploitation sites and went back to their home- towns infected with the disease. As to the Central and Southern regions in Brazil, he found it was more likely that the disease could have been impor- ted from Bolivia or from the Amazon, via the State of Mato Grosso, and also probably from Paraguay, via the states of Mato Grosso or Parana, in view of its endemic form in those countries much earlier than the discovery. This long period of indemnity was probably determined by isolation due to poor transportation conditions at that time. The follo- wing were also considered strong evidence of the
