Synopsis

Juvenile spring eruption (JSE), also known as juvenile spring eruption of the ears, is considered to be an unusual, localized variant of polymorphous light eruption (PLE). This condition occurs most commonly in male children, aged 5 to 12 years, but has been reported in young adult males. The most common time for presentation of JSE is in the early spring, after sun exposure and when the weather is still cold. It is thought that light sensitivity and cold weather both have a role in the induction of JSE. There is a tendency for JSE to occur in small epidemics, for example, at boys schools or among a group of soldiers.

Lesions arise several hours after exposure to sunlight and cold conditions. Grouped small papules, papulovesicles, or true vesicles occurring on the helices of the ears characterize the lesions of JSE. Vesicles may rupture and crust. Lesions resolve spontaneously, usually within 2 weeks, with minimal to no scarring. Recurrence during the following spring has been reported.

The pathogenesis is unknown, although environmental and genetic factors have been proposed to play a role. However, the only well-established contributing factor has been exposure to ultraviolet (UV) radiation. The spectrum of UV light that induces the condition is UVA, and patients may have other lesions more characteristic of PLE on other body areas.
