Comparison of clinical and laboratory features and treatment responses in patients with clinically amyopathic juvenile dermatomyositis and classical juvenile dermatomyositis.

Close clinical follow-ups with effective treatments are important to prevent complications, such as calcinosis and skin ulcers, that may develop in patients with poorly controlled CAJDM. Anti-p155/140 antibodies may be a useful indicator for detecting amyopathic forms of dermatomyositis in children.
