ABSTRACT
Introduction: onychomycosis is caused by dermatophytes,
yeasts and non-dermatophyte molds. It is a common problem
in dermatology and currently new species are implicated,
among them
Trichosporon spp.
Objective: report the isolation and frequency of
Trichosporon
spp. in patients with onychomycosis from the Mycology Section
at Dr. Manuel Gea González General Hospital and at the
Hospital Universitario de Puebla between 2015-2017.
Methods: observational, descriptive and transversal study.
Mycological studies of all patients with onychomycosis from
the period from 2015 to 2017 were reviewed, and diagnosis
was confirmed by direct examination with koh-chlorazol black
and culture in Sabouraud agar and/or Sabouraud plus antibiotics.
Patients in whom
Trichosporon spp. growth in the culture
medium were identified. The characteristics of the patients are
presented in descriptive statistics.
Results: from 1 408 patients with diagnosis of onychomycosis,
18 (1.2%) were selected corroborated with mycological isolation
of
Trichosporon spp. The median age of the patients was
62 years old. Frequency was higher in women (56%). Regarding
topography, all samples were obtained from the toenails. The
most frequent clinical variety was subungual distal onychomycosis
in 50%.
Conclusion: a frequency of 1.27% of onychomycosis was
found by
Trichosporon spp., predominantly in women. Clinically,
we found a mainly affection for the distal subungual area (50%).
It is recommended to consider
Trichosporon spp. as another
causative agent of onychomycosis.
