[Cutaneous changes in long-standing erythropoietic protoporphyria].

Erythropoietic protoporphyria results in highly increased photosensitivity of the skin. Solar irradiation causes sunburn-like symptoms with erythema, edema and wheals. We report the case of a 60-year-old man suffering from erythropoietic protoporphyria since his childhood who additionally developed chronic cutaneous lichenoid papules in sun-exposed skin areas. Vaporization with both electrocautery and carbon dioxide laser proved to be a successful treatment option.
