Linear atrophoderma of Moulin: treatment with Potaba.

Linear atrophoderma is a rare disease, first described by Moulin in 1992 in 5 patients, clinically characterized by hyperpigmented, depressed band-like areas along Blaschko's lines. To date, the disease has no effective treatment. We report the seventh case of this condition in a 16-year-old girl and discuss clinical and histopathologic findings, emphasizing the benefit of the potassium aminobenzoate (Potaba) treatment which provided an early stabilization of the skin lesions.
