Discoid lupus is a mild form of lupus that only affects the skin. It causes symptoms such as:

• red, circular, scaly marks on the skin that can thicken and scar

• hair loss

Discoid lupus can usually be successfully controlled using medication and by avoiding exposure to direct sunlight. Discoid lupus usually only affects the skin but, in some cases, it can progress to the body’s tissues and and organs.
