title: [Superficial mycoses: casuistry of the Mycology Department of the Instituto Nacional de Higiene "Rafael Rangel", Caracas, Venezuela (2001-2014)].
abstract: The superficial mycoses are very common infectious diseases and therefore are a frequent reason for medical consultation. The aim of this study was to determine the diagnostic frequency of superficial mycoses in the Mycology Department of the Instituto Nacional de Higiene "Rafael Rangel" during 14 years (2001-2014). A retrospective cross-sectional study was performed to review the mycological records of patients with presumptive diagnosis of superficial mycosis. Nails, hairs and epidermal scales were the processed samples. The identification of fungi was performed by macro and microscopic observation of colonies and biochemical and physiological tests, as required of the isolated agent. For the investigation of Malassezia spp. only direct examination was performed. Of the 3 228 samples processed, 1 098 (34%) were positive and their distribution according to the etiological agent was: dermatophytes 79.5%; 10.9% yeasts; non-dermatophytes fungi 5.1% and 4.5% Malassezia spp. The most frequently isolated dermatophyte was Trichophyton rubrum Complex (70.1%), followed by T mentagrophytes complex (15.1%), Microsporum canis (9.4%) and Epidermophyton floccosum (4%). The most frequent ringworms Were: Tinea unguium (66.8%), followed by Tineapedis (16.4%) and Tinea capitis (8.1%). Candida parapsilosis complex (37.5%) was the most frequently isolated yeast and Fusarium spp. (53.6%) was the most isolated among non-dermatophyte fungi, followed by Aspergillus spp. (19.6%) and Acremonium spp. (10.7%). The identification of the etiological agent is essential to guide appropriate treatment. This study constitutes an important contribution to the knowledge of the epidemiology of superficial mycoses in our country.
