Generalized morphea-like lesions arising in mechanically-compressed areas by underclothes.

We report two patients with generalized morphea-like eruptions, the distribution of which was confined to areas mechanically compressed by underclothes. One patient had Raynaud's phenomenon and anti-centromere antibodies, and the other patient had a long history of occupational exposure to organic solvents. We believe that the Koebner phenomenon, resulting from local compression by underclothes, might be responsible for the development of morphea-like lesions in patients with subclinical systemic sclerosis.
