JUVENILE DERMATOMYOSITIS

Abstract

Juvenile dermatomyositis is a severe multisystemic autoimmune disease of uncertain origin, based on chronic perivascular inflammation, involving mainly the skin and the muscles. We present a dermatomyositis case with classical skin involvement, where muscle damage occurred more than a year after disease onset.
