Abstract
Different clinical aspects of Lobo's disease among Caiabi Indians are described. The patients were seen in a native village, outside the Parque Nacional do Xingu, 400 km West of said Reservation. Distinct dermatological aspects were found. Some dermatological aspects are suggestive of an intense immunological reaction, lesions are evolutive and caseification and ellimination of parasites occurs. There are multiple lesions and an invasive behaviour of the disease. Such cases are classified as a hypperergic group of clinical manifestations. In other group of dermatological aspects, there is a certain tolerance between the system and the pathogenic organism. Lesion is usually an isolated only one. There is no tendency to caseification and suppuration. The invasive characteristic is absent. This group of dermatological pictures is supposed to be a hypoergic group. Classification of dermatological pictures, as attempted ior the first time by D. Silva and establishment of a nomenclature is emphasized as a most convenient step in order to facilitate scientific comparison of case descriptions and to establish a starting point ior sound immunological research on Lobo's disease.
