Lichen striatus following solarium exposure.

Two cases of lichen striatus occurring after solarium exposure are presented. Both patients were adult females who regularly attended a solarium prior to the development of their skin lesions. A 19-year-old woman attended the solarium twice weekly for 8 weeks prior to the appearance of lichen striatus on the chest and epigastrium. The condition resolved completely with the twice daily application of calcipotriol ointment for 6 months. The second patient, a 40-year-old woman, attended the solarium once weekly for 3 months before lichen striatus developed on the abdomen. She was treated with clobetasol propionate ointment, calcipotriol ointment and intralesional triamcinolone acetonide and the eruption cleared 7 months after onset. The histopathological picture in both patients supported a diagnosis of lichen striatus.
