Leukocytoclastic vasculitis in urticaria induced by sun exposure.

Background: Solar urticaria manifests itself immediately after solar or artificial light exposure and disappears a little later. Histopathologic findings of solar urticaria are essentially identical to those of classic urticaria.

Case Report: We report a 41-year-old man who developed urticarial lesions some hours after sunlight exposure, which resolved after approximately 1 week.
