Previous issue date: 2005-09-21 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Dermatomycoses are fungal infections that attack the skin, hair and nails, in addition to the mucosal and cutaneous-mucosal zones. Objective: Observe the frequency of dermatomycoses, identify etiological agents and establish an association between the results and sex. Age, collection site, time and lesion location. Methods: Between February, 2002 and December, 2004, samples were collected from patients at Giselda Trigueiro Hospital in Natal, Brazil, by lesion scraping and hair removal, following 70% alcohol disinfection, and submitted to direct and culture examination. Results: Of the 817 lesions collected, 325 (39.8%) were fungus positive, with the hair collection site yielding the highest number of positive results (65.8%) and the scalp and hair representing the most frequent lesion sites (65.9%). Negative results occurred mainly in the lower limbs (78.6%). Of the species identified, 55.9% were yeasts, 41.6% dermatophytes and 2.5% Fusarium spp. Non-albicans Candida was the most isolated yeast (43.3%), mainly in females (61.7%) over the age of 40 years (56.4%). T. rubrum was the most isolated dermatophyte (67.9%),notably in males (59.2%) in the 0-20 age group (44.7%). With respect to collection site, 73.9% of the dermatophytes were present in the skin and 61.1% of the yeasts in the nails. When assessing the collection site, the inguinocrural regional was 22.6% positive for dermatophytes, and the nails and hands, 41.8% for yeasts. Conclusions: The results obtained verified that: most of the positive lesions were found in the hair, whereas skin and nail lesions yielded more negative results; T. rubrum was the most isolated dermatophyte and non-albicans candida the most commonly found yeast; positivity was greater in males in the 0-20 year age group at the skin site and in the inguinocrural region, while yeasts were more frequent in females in the over-40 age group at the nail sites / As dermatomicoses s?o infec??es f?ngicas humanas que atingem pele, p?los e unhas, al?m de mucosas e zonas cut?neo-mucosas. Objetivo: Observar a freq??ncia das dermatomicoses, identificar os agentes etiol?gicos e estabelecer uma associa??o dos resultados encontrados com sexo, idade, s?tio de coleta, tempo e local da les?o. M?todos: No per?odo de fevereiro de 2002 a dezembro de 2004, as amostras foram coletadas de pacientes atendidos no Hospital Giselda Trigueiro, por meio da raspagem das les?es e remo??o dos p?los, ap?s desinfec??o com ?lcool a 70%, e submetidas ao exame direto e cultura. Resultados: Das 817 les?es coletadas, 325 (39,8%) foram positivas para fungos, sendo o s?tio de coleta p?los o respons?vel pelo maior n?mero de resultados positivos (65,8%), e couro cabeludo e cabelos foi o local de les?o mais freq?ente (65,9%). Resultados negativos ocorreram principalmente nos membros inferiores (78,6%). Quanto ?s esp?cies identificadas, 55,9% eram leveduras, 41,6% dermat?fitos e 2,5% Fusarium spp. Candida n?o albicans foi a levedura mais isolada (43,3%), principalmente no sexo feminino (61,7%), com idade acima de 40 anos (56,4%). T. rubrum foi o dermat?fito mais isolado em 67,9% dos casos notadamente no sexo masculino (59,2%) e na faixa et?ria de 0-20 anos (44,7%). No tocante ao s?tio de coleta, 73,9% dos dermat?fitos estavam presentes na pele e 61,1% das leveduras nas unhas. Ao se avaliar o local da les?o, a regi?o inguno-crural apresentou positividade de 22,6% de dermat?fitos e as unhas das m?os, 41,8% de leveduras. Conclus?es: Diante dos resultados obtidos, constatou-se que: a maioria das les?es positivas foi encontrada nos p?los, enquanto les?es de pele e unhas geraram mais resultados negativos; T. rubrum foi o dermat?fito mais isolado e Candida n?o albicans a levedura mais presente; a positividade por dermat?fitos foi maior no sexo masculino, na faixa et?ria de 0-20 anos, no s?tio de coleta pele e na regi?o inguino-crural, enquanto que as leveduras foram mais freq?entes no sexo feminino, na faixa et?ria acima de 40 anos, no s?tio de coleta unhas e nas unhas das m?os
