Tumoral calcinosis and atypical juvenile dermatomyositis: case report.

Tumoral calcinosis is a rare, benign calcification of soft tissues in periarticular areas. It can manifest as an isolated disease or as part of an underlying disorder. We report a case of a 6-year-old girl who presented with tumoral calcinosis of her left knee in association with atypical juvenile dermatomyositis. Finally, we discuss operative and non-operative treatment strategies of tumoral calcinosis in children and adults.
