[Juvenile spring eruption (author's transl)].
Juvenile spring eruption is seen in early spring and needs a combination of different factors such as light exposure and chilling. It affects mainly boys aged 5-15 or young male adults. It involves the ears in most of the cases and may itch. The helix develops reddish papules, many of which becoming vesicular and later on crusty. Sometimes papular lesions appear on the back of the hands. The lesions heal within 2 weeks without scarring. Recurrences during following springs can be seen. Juvenile spring eruption cannot be reproduced. Histopathology study performed on 2 cases reveals a picture close to erythema mulutiforme and confirms Burckhardt's findings.
