Solar urticaria successfully treated with intravenous immunoglobulins.

Background: Idiopathic solar urticaria (SU) is a rare type of physical urticaria, occurring immediately after exposure to visible or ultraviolet (UV) light. Treatment is based on sun avoidance and on high doses of antihistamines, but is sometimes inefficient.

Methods: We report on a 41-year-old patient with severe SU who was successfully treated with a single course of 2 g/kg of intravenous immunoglobulins (IVIG).
