Solar urticaria (SU) is a rare photodermatosis characterized by development of urticarial papules and plaques within minutes of exposure to ultraviolet (UV)A, UVB, or visible light. It is an immunoglobulin (Ig)E‐mediated photodermatosis likely caused by a photo allergen activated by a particular light spectrum. Solar urticaria has significant impact on patient's quality of life and often poses a therapeutic challenge. We present the case of solar urticaria induced by visible light in a 33‐year‐old man that presented as an erythematous, urticarial plaque after 15‐minute exposure to fluorescent light while receiving omalizumab therapy.
