RESUMO
Darier's disease (DD) is a dominantly inherited genodermatosis with highly variable expression. It is characterized by symmetrical hyperkeratotic papules affecting seborrheic areas and extremities. The existence of unsightly lesions could lead to discomfort and social handicap. Conventional treatment consists of topical and systemic steroids and/or retinoids alleviating DD. Ablative lasers also have been used to treat these conditions with variable results and side effects. To the best of our knowledge, fractional CO2 laser has never been used to treat DD. We present a case of a 36-year-old woman with verrucous and hyperkeratotic plaques of the forehead significantly improved after two sessions of fractional CO2 laser treatment. Neither scars nor pigmentary disorders were noted.

Linear atrophoderma of Moulin is an acquired rare and self-limited skin condition. It is characterized by atrophic bandlike skin lesions that often show hyperpigmentation and always follow the lines of Blaschko. Usually it begins in childhood or adolescence and there is no evidence of any long term progression. We describe a case of a 21-year-old woman with clinical and histological features of linear atrophoderma of Moulin. The patient was successfully treated with methotrexate 20 mg/week during 6 months with an improvement of skin pigmentation and atrophy. Approximately, 30 cases of linear atrophoderma of Moulin were described in the literature. There is not a proven effective treatment of this dermatosis. High dose penicillin, topical corticosteroids, heparin, and oral potassium aminobenzoate have been used but found to be uneffective. To our knowledge, this is the first case of extensive linear atrophoderma of Moulin treated with methotrexate.
