<p>Fungal infections of the skin are a frequent infectious skin disease in childhood. In particular, the close skin contact in communal facilities, contact to animals, the still immature skin barrier and immune defence as well as certain hygienic and climatic conditions facilitate the occurrence. Global migration movements and international travelling activities also contribute to the distribution of new or previously rare pathogens with elevated resistance profiles. The spectrum of cutaneous mycoses ranges from harmless superficial infections up to extensive inflammatory or chronic recurrent trajectories. A differentiated consideration of the spectrum of pathogens, age-related clinical signs, appropriate diagnostic procedures and individually adapted treatment options is essential.</p>
