N: 1. lupus (n): late 14c., used of several diseases that cause ulcerations of the skin, from Medieval Latin lupus, from Latin lupus “wolf”, apparently because it “devours” the affected part.
lupus erythematosus: New Latin, literally, erythematous lupus. First Known Use: 1860
2. lupus erythematosus, also called lupus, an autoimmune disorder that causes chronic inflammation in various parts of the body. Three main types of lupus are recognized—discoid, drug-induced, and systemic.
Discoid lupus affects only the skin and does not usually involve internal organs. The term discoid refers to a rash of distinct reddened patches covered with grayish brown scales that may appear on the face, neck, and scalp. In about 10 percent of people with discoid lupus, the disease will evolve into the more severe systemic form of the disorder.
