Linear Atrophoderma of Moulin: A Case Report

Abstract

Linear Atrophoderma of Moulin is a rare skin condition that is characterized by the development of one or more atrophic patches or depressions in the skin. These patches are usually located on the trunk, but they can also occur on the arms, legs, and neck. We here present a case of 33-year Nepalese male with brown to black color lesions over the left upper back, abdomen and thigh for the last 7 years. Clinical and dermatopathological findings were similar to the Linear Atrophoderma of Moulin. To our knowledge, this is the first case of LAM from Nepal. This case emphasizes the necessity of diagnosing Atrophoderma of Moulin and separating it from linear scleroderma due to differences in therapy and prognosis.
