Spring eruption of the ears is a distinctive photo-dermatosis characterized by the onset of papules and vesicles on the light-exposed helix of the ears that usually develop in the early spring months and mainly affect juvenile males. Histologically the picture evolves according to evoluntionary stage of the lesions from a nodular dermal inflammatory infiltrate in papular lesions to subepidermal blisters in vesicles. The striking and isolated location on the ears and its onset as small outbreaks are clinical features resulting from unknown mechanisms.
耳部春季疹是一种独特的光线性皮肤病，其特征为耳部暴露于光线的耳轮上出现丘疹和水疱，通常在早春时节发病，主要影响青少年男性。从组织学上看，病变的表现会根据病变的演变阶段而变化，从丘疹性病变中的结节性真皮炎症浸润发展为水疱中的表皮下水疱。耳部显著且孤立的发病部位以及以小范围发作开始的特点是由未知机制导致的临床特征。
