ABSTRACT

Onychomycosis is frequently caused by dermatophyte but some non-dermatophytic moulds like Aspergillus sp., can also be involved. We report nine cases of onychomycosis due to Aspergillus species diagnosed in two different dermatologic centers in Mexico City and in Mérida, Yucatán. All patients were females with an age ranged from 13 to 79 years old, with higher incidence in the fourth decade of life. The clinical features were subungueal keratosis in six patients and onycholysis in five. History ranged from three weeks to 21 years. The koh was positive in nine patients, with aspergillar heads observed in two cases and in the other cases hyphae and/or spores. The isolated agents were A. Terreus in three cases, A. Flavus in two cases, A. Niger in two cases, A. Versicolor in one case and Aspergillus sp. in two more cases; one of them had two isolated agents: A. Terreus and A. Niger. Treatment and follow-up was completed in four patients, one of them responded to oral itraconazol, one to topical bifonazole-urea, another to the combination of both and one more to surgical nail avulsion.
