Calcinosis as the presenting sign of juvenile dermatomyositis in a 14-month-old boy.

We describe a 14-month-old child with dermatomyositis in whom calcinosis was the first sign of the disease. This case shows that calcinosis, usually a late complication of dermatomyositis, may be the presenting sign of the disease even in young children and when Gottron's sign is still absent and muscular weakness not prominent.
