title: Calcinosis in juvenile dermatomyositis mimicking cold abscess.
abstract: We report a case of dystrophic calcification presenting as soft cystic swelling in a patient with juvenile dermatomyositis. A 15-year-old boy with lumbosacral cystic swelling, which was considered a cold abscess clinically, was evaluated for nonresponse to antitubercular therapy. The cystic swelling had liquefied calcium with a well circumscribed calcified wall on imaging, which was subsequently excised.
