Overview

Systemic lupus erythematosus (SLE) must be differentiated from other diseases that cause skin rash, arthritis, positive autoimmune serology, weight loss, fevers and chronic pain, such as rheumatoid arthritis(RA), mixed connective tissue disease (MCTD), systemic sclerosis (SSc), dermatomyositis (DM), polymyositis(PM), and other autoimmune diseases.
