Two Patients with Solar Urticaria Manifesting Pruritic Erythema

Open publisher page 10 citations

Abstract

Two patients with solar urticaria are described. They complained of transient pruritic erythema, but not frank wheal, on sun-exposed areas. However, urticarial wheals were elicited by polychromatic radiation in the ultraviolet and visible light ranges; the action spectra for solar urticaria ranged from 400 to 550 nm in case 1 and from UVA to 550 nm in case 2. In patients manifesting only transient pruritic erythema on sun-exposed areas, phototests are essential for making a confident diagnosis of solar urticaria.
