Linear atrophoderma of Moulin localized to the neck

Linear atrophoderma of Moulin (LAM) is a rare and distinct skin condition characterized by unilateral, hyperpigmented and atrophic band-like skin lesions following the lines of Blaschko. Usually the disease begins in childhood or adolescence on the trunk or limbs, with no preceding inflammation or subsequent sclerodermatous changes. Approximately 25 cases have been reported in the English language literature. We describe a case of LAM occurring in a 9-year-old Peruvian boy with exclusive involvement of the neck. To our knowledge, this is the first report of LAM with this unusual localization.
