What are the complications of discoid lupus?

If a discoid lupus rash occurs on your scalp, it may cause hair loss. If a scar forms on your scalp, the hair loss may be permanent.

Having a discoid rash that lasts a long time may increase your risk for skin cancer. Discoid sores inside your mouth can increase your risk for a type of skin cancer called squamous cell carcinoma.

Rarely, people may develop chilblain lupus erythematosus. Chilblain lupus causes purple skin patches or lesions that worsen after exposure to cold temperatures. These lesions are often very painful.
