Are there different diseases?

Answer:

• Systemic lupus erythematosus (eh-RITH-eh-muh-TOE-sus) is the most common form. The word "systemic" means that the disease can involve many parts of the body. SLE symptoms can be mild or serious.
• Discoid lupus erythematosus mainly affects the skin. A red rash may appear, or the skin on the face, scalp, or elsewhere may change color.
• Drug-induced lupus is triggered by a few medicines. It's like SLE, but symptoms are usually milder. Most of the time, the disease goes away when the medicine is stopped. More men develop drug-induced lupus because the drugs that cause it, hydralazine and procainamide, are used to treat heart conditions that are more common in men.
