ABSTRACT

Introduction: Tinea incognito or atypical is a dermatophytic infection in which the treatment with steroids has modified its clinical characteristics. This infection tends to spread and can be confused clinically with other skin diseases, making difficult its diagnosis. There are few studies about its prevalence and incidence. Objective: To determine the incidence and clinical aspects of tinea incognito in the Centro Dermatológico «Dr. Ladislao de la Pascua». Material and methods: A cross-sectional study was performed in the micology laboratory from January 2011 to December 2013 to identify the patients with the diagnosis of tinea incognito. Results: The incidence of tinea incognito was 3.8 per 100 cases of tinea per year, more than 50% had involvement of the face, trunk and groin. The tinea was more common in women with a median age of 39 years. The most frequently isolated fungus was Trichophyton rubrum. The clinical diagnoses were: annular granuloma (25%), nummular dermatitis (19%) and lupus erythematosus (13%), among others. Conclusion. Tinea incognito has an incidence consistent with the data reported in previous studies.
