Discoid lupus erythematosus, Subacute cutaneous lupus erythematosus
A chronic, inflammatory, connective tissue disease that can affect the joints and many organs, including the skin, heart, lungs, kidneys, and nervous system. It can cause many different symptoms; however, not everyone with systemic lupus erythematosus has all of the symptoms. Disease that results when the immune system mistakenly attacks the body's own tissues. Examples include multiple sclerosis, type 1 diabetes, rheumatoid arthritis, and systemic lupus erythematosus. Chronic. Refers to disorders that last a long time, often years. When people use the term “lupus,” they usually refer to systemic lupus erythematosus, or “SLE.” Throughout this website, the term “lupus” is used to signal systemic lupus, since SLE constitutes the most common form of the disease. Systemic lupus is so-named because it affects many different organ systems in the body. The term “chronic cutaneous lupus erythematosus” refers to a specific form of lupus that is limited to the skin. This form of lupus can exist in people who do not have systemic lupus. However, five percent or more of the people with this form of lupus may develop SLE later in life. This topic focuses on systemic lupus erythematosus (SLE), the most common and most serious type of lupus. But there are other types of lupus, such as discoid or cutaneous lupus, drug-induced systemic lupus, and neonatal lupus. The exact cause of lupus is not known.  Systemic Lupus Erythematosus (SLE). Systemic Lupus Erythematosus (SLE) is typically the most common form of lupus and is generally considered more serious than the other three forms. SLE can affect many parts of a person’s body, including kidneys, heart, lungs, brain, blood and skin. Symptoms tend to vary among patients and can change often and suddenly. Although not limited to the SLE type, lupus can follow an unpredictable pattern of remissions (symptoms disappear) and flares (active symptoms).  Symptoms of systemic lupus erythematosus (SLE, often referred to as simply lupus) can be quite different, because there are different types of lupus, and not all affected people show the same symptoms. General symptoms associated with lupus include. 1  low-grade fever, 2  loss of appetite, 3  nausea, 4  muscle aches, 5  joint pains, 1 Systemic lupus erythematosus (SLE) is an autoimmune disease. 2  SLE is characterized by the production of unusual antibodies in the blood. 3  The cause(s) of SLE is (are) unknown, however, heredity, viruses, ultraviolet light, and drugs all may play some role. There are many autoimmune diseases, including systemic lupus erythematosus (SLE). SLE is also known as discoid lupus or disseminated lupus erythematosus. Although “lupus” actually includes a number of different diseases, SLE is the most common type of lupus, and when people say “lupus,” they are often referring to SLE. SLE is a chronic disease that can have phases of worsening symptoms that alternate with periods of mild symptoms. There are many kinds of lupus. The most common type is systemic lupus erythematosus (SLE), which affects many internal organs in the body. SLE most often harms the heart, joints, skin, lungs, blood vessels, liver, kidneys, and nervous system. Systemic lupus erythematosus, often abbreviated as SLE or lupus, is a systemic autoimmune disease (or autoimmune connective tissue disease) in which the body’s immune system mistakenly attacks healthy tissue. About Lupus. Lupus is an autoimmune disease that can affect various parts of the body, including the skin, joints, heart, lungs, blood, kidneys, and brain. Normally, the body's immune system makes proteins called antibodies to protect the body against viruses, bacteria, and other foreign materials. Disease that results when the immune system mistakenly attacks the body's own tissues. Examples include multiple sclerosis, type 1 diabetes, rheumatoid arthritis, and systemic lupus erythematosus. Chronic. Refers to disorders that last a long time, often years. The most common type, systemic lupus erythematosus, affects many parts of the body. Other types of lupus are: 1  Discoid lupus erythematosus—causes a skin rash that doesn't go away. 2  Subacute cutaneous lupus erythematosus—causes skin sores on parts of the body exposed to sun.
