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.

Juvenile spring eruption is a distinct photodermatosis characterized by the development of papules and vesicles on light-exposed areas of the ears usually in the early springtime. It primarily affects boys and young men, and has a tendency to occur in the form of small epidemics. We report a similar outbreak in separate groups of soldiers who were performing military exercises during cold and sunny weather of a midwinter season. The clinicopathologic features and phototesting results are described in 4 of these cases. All patients showed normal erythemal responses to monochromator phototesting with UV and visible wave bands. Photoprovative testing with repeated daily exposures of the ears to a broadband UVA source provoked diffuse erythema and itching in 1 case, whereas similar photoprovocation of a nonaffected area, ie, the flexor surface of the forearm, in 2 patients did not yield a skin reaction. Although the cause of juvenile spring eruption is not known, our observations further strengthen the hypothesis that the disorder is a localized variant of polymorphous light eruption.
