Dermatomyositis Presenting with Generalized Subcutaneous Edema.

Generalized subcutaneous edema is rare in dermatomyositis. We herein report an 82-year-old woman with dermatomyositis who presented with generalized subcutaneous edema. Three weeks before admission, she first noticed facial edema, and the symptoms exacerbated, with limb edema occurring. On admission, muscle weakness in the limbs and skin rash were noted. Her muscle enzyme levels were elevated, and serum anti-transcriptional intermediary factor 1-γ antibody was detected. She was diagnosed with dermatomyositis and treated with corticosteroids and tacrolimus, which improved her muscle weakness, muscle enzymes, and edema. Thus, generalized subcutaneous edema can occur during dermatomyositis, with facial edema as the initial symptom.
