A number of rheumatologic diseases are associated with skin manifestations, and some of them may present predominantly with skin changes. These include rheumatoid arthritis, lupus erythematosus, scleroderma and dermatomyositis. The diagnosis of these diseases is usually made from suggestive clinical features, laboratory tests and skin biopsies. A multidisciplinary approach to management is often adopted, involving the rheumatologist, dermatologist and other specialists where necessary.
