Perioral dermatitis is common in children and, if untreated, characterized by a chronic course lasting for months. Provocation factors known for adults, especially topical or inhaled corticosteroids, are relevant in children as well. We present eight children - all of them with dry skin - who developed perioral dermatitis after using sunscreens based on micropigments. This suggests that children with dry skin are at increased risk for perioral dermatitis. A history of sunscreen use should be specifically sought in children with perioral dermatitis.

A 42-year-old man presented with a tender area on the sole of his right foot. Over the previous few days, he had noticed a linear, erythematous, continuously migrating skin lesion. While an internet search had led the patient to suspect cutaneous larva migrans, he himself doubted the diagnosis, given the absence of a travel history.
