Hard as stone: an exuberant form of calcinosis cutis

Dermatomyositis (DM) is an immune-mediated myopathy characterized by proximal skeletal muscle weakness, muscle inflammation, and distinct skin manifestations. Calcinosis cutis, involving the deposition of insoluble calcium salts in the soft tissues, affects approximately 8% of DM patients1 and poses significant treatment challenges. It can complicate with inflammation, ulceration, pain, and local and systemic infections, resulting in considerable morbidity. We present the case of a 69-year-old-woman with dermatomyositis who developed an exuberant form of calcinosis cutis.
