Primary atrophic profound linear scleroderma. Report of three cases.

We present 3 unusual cases of deep linear, primary atrophic scleroderma, not preceded by inflammatory reaction and sclerosis, involving the subcutis and deeper tissues. These cases differ in the course and prognosis from typical profound scleroderma since they do not lead to disfiguration and crippling deformities. In contrast to the atrophies left after regression of morphea or linear scleroderma, they do not involve the dermis, which does not show discoloration or changes in texture. Infiltrates in the endomysium, involvement of deeper tissues and the progressive character of the disease argue for atypical primary atrophic profound scleroderma. The coexistence in one case of primary facial hemiatrophy appears to indicate also its relationship with primary linear atrophies of the limbs. Copyright (R) 2000 by S. Karger AG, Basel
