Abstract:
Polymorphous light eruption(PMLE) is an idiopathic, scquired syndrome characterized by a delayed abnormal response to light and a varied morphology of recurrent erythema, papules, vesicles or plaques on light-exposed areas of skin. We report herein s 42-year-old male patient who was clinically and histologically compatible with PMLE. To confirm the diagnosis, the phototest was performed by 50,J/crn of UVA, 5MED-UVB and visible light irradiation to the extensor surface of the forearm. Numerous erythematous papules developed at the (JVA-irradiated site. The histopathologic findings of the phototest induced lesion were compatible with PMLE. Therefore, our patient was confirmed as having PMLE with action spectrum in the IJVA range.
