Abstract

According to statistics, tinea capitis remains the main mycological problem in childhood. The spectrum of causative agents of tinea capitis varies depending on the continent. In epidemiological terms, the pathogenic fungus Microsporum canis (felineum)absolutely predominates on the Eurasian continent.

A significant problem in the diagnosis and, in particular, in the treatment of microsporia are cases of the disease in very young children: we estimate this most problematic age from 1 to 18 months. Microsporia in children under the age of 1 year is the most relevant in pediatric clinical mycology due to the limited arsenal of topical and systemic medications approved at this age.

The clinical case presented in this article demonstrates an example of successful treatment of scalp microsporia in a 7-month-old child who had contraindications to systemic therapy. It should be noted that the duration of treatment in this case was almost 4 months, while the most effective therapy regimens, including systemic drugs, lead to the elimination of pathogenic fungus from the foci on the scalp within 30–45 days.
