New Epidemiological Outcomes in Anthropophilic tinea capitis, a Case Series Study in Northwestern Spain.

ABSTRACT

Although zoophilic dermatophytes remain the predominant cause of tinea capitis in Spain, an increase due to anthropophilic species has been reported. We report a retrospective observational study that included twenty-four children, who were diagnosed with tinea capitis due to anthropophilic species between 2004 and 2019. 75% of the patients were males with a mean age of 4,88 years. We observed 83,3% of cases from Africa, 4,2% from South America and 12,5% from Spain. Clinically, 70,8% of the patients presented scaly patches and non-scaring alopecia. Trichophyton soudanense was the main dermatophyte of the series (45,8%), followed by Microsporum audouinii (20,8%), Trichophyton tonsurans (12,5%) and Trichophyton violaceum (12,5%). Although this pattern of infection appears to be linked to immigration from Africa, we saw three native cases. The easier transmission of anthropophilic rather than zoophilic dermatophytes could predict a rise in the incidence of tinea capitis and a public health problem.
