title: Juvenile amyopathic dermatomyositis.
abstract: A 3-year-old girl presented with a 6-month history of multiple, light-pink, flat-topped papules over the dorsal aspects of the metacarpophalangeal and interphalangeal joints of the hands and feet. Nailfold telangiectases, ragged cuticles, and a heliotrope color of the upper eyelids were also evident, but there was no clinical evidence of muscle weakness and levels of muscle enzymes were normal. A biopsy specimen from one of the papules showed a vacuolar interface dermatitis consistent with a diagnosis of dermatomyositis. This report draws attention to juvenile amyopathic dermatomyositis, which is an uncommon subtype of dermatomyositis with an excellent prognosis.
