• In the course of dermatomyositis, calcinosis is a complication frequently seen in children but rarely seen in adults. Calcinosis often induces poor functional prognosis, reducing mobility of the joints and muscles. Dermatomyositis developed in a 59-year-old woman, following an antitetanus vaccination; the dermatomyositis later became calcifying. To our knowledge, similar cases have not been reported.
