Psoriasis: Estudio micológico en uñas

Resumen

La psoriasis ungueal es ampliamente conocida y ha sido extensamente estudiada. Sin embargo, se le ha dado poca importancia a su asociación con hongos a excepción de la Cándida.
Con el objeto de determinar la frecuencia de micosis ungueal en pacientes psoriáticos fueron estudiados 27 pacientes (19 hombres y 8 mujeres). A todos se les tomó muestra de material ungueal, se le practicaron 2 exámenes directos y siembra en 4 tubos de medio Agar Sabouraud.
Se aislaron 12 agentes micóticos: 7 Cándidas (25.9%), 2 T. rubrum (7.4%), 1 T. mentagrophytes (3.7%) y 2 mohos (7.4%). La identificación final de
los tipos de Cádidas reportó 5 C. noalbicans. En 9 pacientes (33.3%) se diagnosticaron micosis superficiales en localizaciones diferentes a las uñas.
