{Abstract}: We report a case of a 42-year-old woman (Gravida 1, Para 1) who presented in her third trimester of pregnancy with a photo distributed eruption and arthralgias and was subsequently diagnosed with dermatomyositis. She had an emergency Caesarean section at 34 weeks plus 6 days gestation due to decreased fetal movements and non-reassuring fetal heart rate. Her placenta was sent for histopathology and showed features of massive perivillous fibrin deposition. To our knowledge, this is the first case of MDA-5 positive dermatomyositis in pregnancy with a live delivery.
