LINEAR ATROPHODERMA OF MOULIN - A DISEASE WHICH FOLLOWS BLASCHKOS LINES

Linear atrophoderma of Moulin is a distinctive disease pattern charact erized by hyperpigmented atrophoderma and described originally in 1992 . It follows the lines of Blaschko, and occurs without preceding infla mmation, subsequent induration or scleroderma. The lesions usually dev elop during childhood or adolescence, and the prognosis is good. The d ifferential diagnoses include linear dermatoses, e.g, linear scleroder ma, epidermal naevi, inflammatory linear verrucous epidermal naevus, l ichen striatus, Blaschkitis acuta, reticulate hyperpigmentation of Iij ima and linear lupus erythematosus. Diagnosis is made clinically and h istologically. We report a 22-year-old woman with a 17 year history of linear atrophoderma which involved the right arm and trunk.
