Abstract:
Solar urticaria can be defined as an idiopathic photodermatosis characterized by the occurrence of itchy erythematous or urticarial lesions that are provoked only by sunlight and disappear nearly within 24 hours after avoidance of sun exposure. A 25-year-old male patient was presented with a 7-year history of recurrent wheals and itching, which developed after sunlight exposure. Cutaneous lesions and itching completely subside within 2 hours after avoidance of sunlight. Phototesting for UVB, UVA and visible light were all negative. But provocative test with natural sunlight showed positive result. Histopathologically, edema of papillary dermis and mild perivascular inflammatory infiltrations were seen.
