Abstract

This survey was a retrospective of a 16-year (1993-2008) study on the incidence, clinical features, and etiological agents of tinea capitis mainly representing the Southeastern China. The diagnosis was confirmed by direct microscopic examination. Eight hundred and sixty-six patients with tinea capitis, 381 males (44%) and 485 females (56%), were enrolled in this study. Patients were between 20 days and 84 years old with an average of 10.5 years and the peak incidence was in the age group of 6-10 (48.5%). Five hundred and sixty-two patients (64.9%) were ectothrix and 303 patients (35.0%) were endothrix with only one patient was favus. The incidence of tinea capitis from 1993 was gradually increasing and reaching to its peak in 2001. Positive cultures of dermatophytes were obtained in 715 patients: Microsporum canis (62.4%) was predominant, followed by Trichophyton violaceum (19.0%), Trichophyton tousurans (9.8%). M. canis was the major pathogen for ectothrix infection, while T. violaceum and T. tousurans contributed to the most endothrix form. M. canis, T. violaceum, and T. rubrum were the major pathogens for kerion.
