RESUMEN
La onicomicosis es la patología en uñas más frecuentemente descrita en la literatura. Además de los dermatofitos y las cándidas, otros hongos se han identificado como agentes primarios de onicomicosis, entre ellos Fusarium spp., Aspergillus spp., y Scopulariopsis brevicaulis. En este trabajo se estudiaron 330 pacientes remitidos al laboratorio clínico del Hospital Calderón Guardia, por afecciones en las uñas de los pies. A 206 pacientes se les diagnosticó onicomicosis, de los cuales 119 fueron sólo por examen directo, 83 por examen directo y cultivo, mientras que 4 fueron sólo por cultivo del agente etiológico en forma repetida. Entre los hongos identificados está Fusarium spp., hongo que no responde al tratamiento convencional que se administra a los dermatofitos, lo que resalta la importancia de identificar el agente involucrado en las onicomicosis.
ABSTRACT
Dermatophytes are the most common etiological agent of onychomycosis, however Fusarium sp., Aspergillus sp. y Scopulariopsis brevicaulis have been identified as primary agent. In the present work we attended 330 patients which onychopathies in the clinical laboratory of the Hospital Calderon Guardia. In total 206 patients were diagnosed with onychomycosis. Of these patients, 119 were diagnosed only by direct examination, 83 by both direct examination and culture, and 4 only by culture of the etiological agent. Fusarium sp. was identified among the agents of onychomycosis. This fungus respond very poorly to antifungals commonly use in onychomycosis cause by dermatophytes. Thus, our finding point out the important of the identification of the etiological agent of onychomycosis.
