Edematous myositis: a clinical presentation first suggesting dermatomyositis diagnosis.

ABSTRACT:

Aims

Edema of the limbs is uncommon in idiopathic inflammatory myopathies (IIM). The few reported cases have been associated with severe and refractory dermatomyositis (DM), sometimes in association with cancers.
