Cutaneous lesions of dermatomyositis with supervening fibrosis

Abstract

The identification of sclerosis in biopsies of skin lesions typical clinically for DM may be a harbinger for more severe autoimmune-based endothelial cell injury phenomenon. One could speculate that its basis may be attributable to elevated serum levels of the natural fibrogenic factor, transforming growth factor beta, which in turn is released from damaged endothelium.
