Calcinosis cutis in juvenile dermatomyositis responsive to aluminum hydroxide treatment.

Calcinosis cutis is a frequent complication of juvenile dermatomyositis; however, its treatment remains unsatisfactory. We report a case of calcinosis cutis in juvenile dermatomyositis which was successfully treated with oral aluminum hydroxide. Almost complete clearing of calcinosis was observed after 8 months of therapy. There were no adverse effects from therapy. Aluminum hydroxide is worth trying in treating calcinosis cutis.
