Linear atrophoderma of Moulin


We present a 40-year-old woman with asymptomatic, linear, hyperpigmented atrophic plaques in a Blaschkoid distribution on the right back and right upper extremity that is consistent with a diagnosis of linear atrophoderma of Moulin. Clinical lesions developed with a biphasic pattern in late adolescence and in adulthood. The pathogenesis of this acquired, progressive Blaschkolinear dermatosis may hold insight into the pathogenesis of this rare dermatologic condition, as well as other dermotoses, which include those resulting from post-zygotic genetic mosaicism.
