Video Summary

Dermatomyositis (DM) is a rare autoimmune disease that leads to inflammation and damage of the muscles and skin. It is associated with complement system activation, and autoantibodies like ANA, anti-Mi-2 and, anti-Jo-1 which result in proximal muscle weakness and photosensitive skin rashes. DM presents with muscle weakness, which often becomes worse over time, as well as a distinctive skin rash.
