Study design: Clinical retrospective. Material and method: develop this research it had been realized a retrospective in reference book of 187 patients proceeding from the Infectology Service at the Deep Mycosis Ambulatory at Federal University of Paraná, in Curitiba, between may 1985 and march 1998. The purpose of this paper was to delineate the epidemic outline describing the stomatologicals manifestations found in the sample, to discuss about the data found and to establish comparison with the pertinent literature, to observe possible changes and if they were significant as well as to notice the dyes sensibility that were used in the histopathology (HE, PAS and GROCOTT), in 20 microscopic slides. It had been settled a previous protocol to get the data concerning to the desease epidemiology such as oral manifestations, describing the kind and localization of the lesions. In the results that were found, references like sex, age, naturalness, origien and profession of the patients were determinant factors in the epidemiologic and demographic outline of the sample studied (187 cases) compared with the pertinent literature. Results: The evaluation of the results showed changes that were not to much significant in relation to the desease epidemiology. On the other hand, it was evidenced the exuberance in oral manifestations of the desease that is very commom and frequently leads the patient to a worse condition or even to a maintenance of the desease by the difficulty of nutrition that increases the immunesuppression. In the sample of these 187 patients studied, 167 (89,3%) were male and 20 (10,7%) female. In relation to the age, 75 (40,1 %) were between 40 and 50 years, with some relevant aspects:81 patients (43,3 %) were agricultural workers, 93 (49,7 %) were from inland areas of Paraná. The loss of weight was related in 72 (17,22%) of the 187 complaints, followed dyspnea. In relation to the shape of the lesions, 85 (41,46%) of the patients did not show visible, the most commom were the ulcerated ones, the granulomatuos ones, followed by moriform one. The place with major incidence of lesions were lips, followed by oropharynx and hard palate, it was also noticed more than one kind of lesion in the same patient, between these 187 patients, five (2,65%) showed also tuberculosis, 140 (72,54%) did not palpable lymphonodes, 127 (67,91%) of the patients denied to use alcoholic drinks, 117 (62,57%) were smokers. The pulmonary envelopment was predominant in 166 (51,78%) of the analized cases. In the histopathology, the technique of dyeing by silver (GROCOTT) showed it self more sensitive than HE and PAS for visualization in demonstration of the etiologic agent P. brasiliensis.
