ABSTRACT

Background: superficial white onychomycosis is a rare variant in which the surface of the nail plate is affected and is manifested by white discoloration. The main etiological agent is Trichophyton interdigitale and T. rubrum.
Patients and methods: a cross-sectional and retrospective study was conducted, which included patients referred to the mycology section due to clinical suspicion of superficial white onychomycosis (SWO), at Dr. Manuel Gea González General Hospital, from 2013 to 2022. With the objective of analyzing the frequency of this variant, and to report the epidemiological and mycological data of cases confirmed by mycological study.
Results: swo was verified in 33 patients. Twelve fungi were isolated, seven dermatophytes (58.3%) T. rubrum and T. Mentagrophytes, two non-dermatophyte molds (16.6%), two Candida spp. (16.6%) and one Trichophyton spp. (8.3%). There were 19 immunocompetent patients (57.5%), and 14 patients with comorbidities (42.5%), nine with hiv (27.2%), three with autoimmune diseases (9.09%) and two patients with cancer (6.06%).
Conclusions: superficial white onychomycosis is a rare clinical type of onychomycosis, whose most common etiological agent in our environment is Trichophyton rubrum.
