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.
