Discoid lupus article

The rash varies from a mild pinkness, often brought out by ultra-violet (UV) light, to a florid lumpy and disfiguring rash, which comes and goes. It is a feature of active disease and usually disappears as the disease goes into remission. There is thickening of the skin and a scaliness, which often becomes red and ‘angry’.
The main sites of the discoid lupus lesions in these patients were the face and the scalp. Nine of the patients tested positive for ANA antibodies.
Some patients have chilblain-like patches on their fingers and toes. When the scalp is involved, hair in the affected area may be permanently lost.
