Background: Tinea is a superficial mycoses caused by pathogenic, keratin digesting fungi, called dermatophytes. In Mexico, the most frequent agent is Trichophyton rubrum, and on the other hand, Microsporum gypseum is the most important geophilic one, however this is infrequent. Objective: To determinate the frequency and prevalence of M. gypseum infections in a Dermatological Center of Mexico. Methods: Descriptive, retrospective, observational and transversal study of a 14 years (2002 - 2016) period. All the patient charts with tinea due to M. gypseum confirmed by culture were included. The following data were analyzed: gender, age, occupation, provenance, time of onset and clinical features. Descriptive statistics were used. Results: A total of 3,921 mycological studies were done with 64 isolations of M. gypseum (1.7% of the total). 21.88% were students and 20.32% were mature adults. The body regions involved were head/neck (34.3%), trunk (21.8%), forearms (15.6%) and thighs (10.9%). Study Limitations: Some limitations of our work were the study period and the number of negative cultures from the total performed at our micology laboratory. Conclusions: Microsporum gypseum has a wide world distribution however clinical cases due to this agent are scarce. This is one of the largest compilations of clinical cases due to this pathogen. Students and housewives were the main affected. It could be due to play on the ground, contact with pets, or domestic duties. [ABSTRACT FROM AUTHOR] |
