ABSTRACT

Onychomycoses are infectious diseases caused by fungus in the nails of hands and feet which are produced by dermatophytes, yeasts and or molds.
Dystrophy refers to the degeneration or misdevelopement of any part of the body —in this article we refer to lesions of the nails— caused by various reasons, amongst them those of traumatic and/or fungal origin.
We performed a prospective, observational, descriptive and transversal study in 100 patients of the Instituto Dermatológico Jalisco “Dr. José Barba Rubio”with the objective to find the frequency of mycosis in the fifth toenail using clinical examination, an epidemiologic questionnaire and mycological studies for investigation.
Our results: We found onychomycosis in 21% of all studied cases, observing T. rubrummost frequently as etiological agent in 33.3% of cases 100% of the clinical presentation of onychomycosis was total nail dystrophy. The predominating dystrophic alteration was the combination of pachyonychia and melanonychia.
In conclusion, we consider it is always important, especially observing dystrophic changes in the nail of the fifth digit of the foot, to perform a mycolo-gical study in order to confirm the presence or absence of fungal infection, which is of interest for an adequate treatment of our patients.
