Juvenile dermatomyositis (JDM) is an inflammatory, non-pustular disorder of skeletal muscles and skin. Other organs, such as the lungs, can be involved. Pulmonary complications are associated with high morbimortality rates and can develop in the acute phase of the disease. Due to its rarity, diagnosis difficulty and severity pulmonary involvement, we report the case of a 3-year-old girl with JDM and pulmonary involvement and evolution to death.
