Right again
This is Dermatomyositis with purple heliotrope rash on upper eyelids with periorbital edema....also has grutton'slesions on knucckles,elbows,knees[erythematous crusted lesions]...It is different from polymyositis in the sense that in polymyositis one finds endomysial lymphocytic infiltrates.Both have bilateral[symmetrical] proximal muscle atrophy.
