    TLDR A young girl's foot lesion was actually a rare condition caused by a hair fragment under the skin, not a parasite.
    A 19-month-old girl in Switzerland was suspected of having larva migrans due to a moving lesion on her foot, which appeared after playing in a park. However, it was identified as cutaneous pilus migrans, a rare condition where a hair fragment embeds in the epidermis and migrates. This condition is often asymptomatic and can be mistaken for larva migrans, which is not endemic in Switzerland. Dermoscopy can aid in diagnosis, and the condition is typically caused by a hair fragment penetrating the skin, possibly facilitated by wet conditions. The lesion in this case was not painful or itchy, and the child had no other symptoms.
