Autoimmune collagen vascular diseases: Kids are not just little people.

Morphea, dermatomyositis (DM), and discoid lupus erythematosus (DLE) are autoimmune collagen vascular diseases that can present at any age. In all three of these diseases, the tenants of diagnosis and treatment are largely the same in both children and adults, with a few notable differences. Children with morphea are more likely to present with the linear subtype and have a higher incidence of extracutaneous manifestations.
