ABSTRACT

Background: Tinea Capitis is a superficial fungal infection with low morbidity. It is the most common dermatophytosis in children and is highly prevalent in low socioeconomical level. Non inflammatory Tinea Capitis is the most frequent. In Mexico the common etiologic agents are Microsporum Canis and Trichophyton Tonsurans.
Objectives: To present clinical and mycological data of Tinea Capitis in 114 cases studied during a six year period in a dermatological clinic in Yucatán, México.
Methodology: A descriptive and retrospective study was performed at the dermatologic clinic “Dr. Fernando Latapí” in Yucatán, México. All cases with a clinical diagnosis of Tinea Capitis were referred to the mycology laboratory since 2001 to December 2007. Skin scrapings and hair samples were taken for KOH mounts and mycological culture.
Results: One hundred and fourteen cases were studied. No significant difference in sex ratio was observed: male 58 (50.9%) v. female 56 (49.1%). The mean age at diagnosis was 5.5 year and ranged from one month to 13 years. Elementary schoolers represented 51% of the whole group, followed by preschoolers (43.9%). The average time of evolution was 6 weeks. Non inflammatory and inflammatory Tinea Capitiswere equally distributed. The main etiologic agent of noninflammatory tinea was M. Canis followed by T. Mentagrophytes, and for the inflammatory type T. Mentagrophytes followed by M. Canis.
Conclusions: We found a similar frequency in cases of inflammatory and noninflammatory Tinea Capitis. The most frequent etiological agent in this cohort of patients was M. Canis followed by T. Mentagrophytes.
