Polymositis and Dermatomyositis in Cats
 
Polymositis and dermatomyositis are both generalized disorders which involve the inflammation of the cat's muscles. More specifically, polymyositis involves skeletal muscle damage due to inflammation, but with no pus formation, whereas dermatomyositis is a form of polymyositis in which characteristic skin lesions are also seen.
