White spots on the surface of the toe nails is characteristic of this common superficial onychomycosis. The usual causal organism is Trichophyton mentagrophytes. Cephalosporium roseo-griseum. Aspergillus terreus and a member of the Fusarium oxysporum group are less common causes. Fungus invasion may occur anywhere on the surface of the toe nail and does not evoke the characteristic inflammatory reaction seen in ordinary subungual dermatophytosis. The hostparasite relationship is noteworthy, for although the fungus is growing “in-vivo” on the surface of the nail, it exhibits saprophytic features. Manchas blancas en la superficie de las uñas de los pies son caracteristicas de esta onicomycosis superficial común. El agente causal principal es el Trichophyton mentagrophytes. Cephalosporium roseogriseum, Aspergillus terreus y Fusarium oxysporum también son capaces de producir esta infección superficial. El hongo puede invadir cualguier area de la superficie de la uña y no produce la reacción inflamatoria caracteristica que existe en la onicomycosis subungual. La relación entre el hongo y la uña presenta caracteristicas, especiales porque, aunque el hongo crece en la superficie de la uña “en-vivo” manifiesta caracteristicas morfologicas saprofíticas.
