Abstract

A 26-year-old woman who had myasthenia gravis (MG) experienced several instances of sunburns. A phototest was performed by ultraviolet (UV) A, UVB and visible light irradiation to the back surface of the sunburns. Numerous erythematous papules developed at the 20, 25, 30 J/cm2 UVA irradiated site. The phototest induced lesions were compatible with polymorphic light eruption (PMLE) with action spectrum in the UVA range. After immunosuppresant treatment, the MG and PMLE were in a well-controlled state. We report MG associated with PMLE followed with a literature review. Key Words: Myasthenia gravis, Polymorphic light eruption
