Subacute cutaneous lupus erythematosus
Subacute Cutaneous Lupus Erythematosus (pronunciation: sub-acute cutaneous lupus ery-them-a-toe-sis) is a subtype of Lupus Erythematosus, a chronic autoimmune disease.
Etymology
The term "Subacute Cutaneous Lupus Erythematosus" is derived from the Latin words "sub" meaning under, "acutus" meaning sharp, "cutis" meaning skin, "lupus" meaning wolf, "erythema" meaning redness, and "osis" meaning condition.
Definition
Subacute Cutaneous Lupus Erythematosus (SCLE) is a form of Lupus that primarily affects the skin, causing lesions that are photosensitive and non-scarring. It is characterized by skin eruptions that may appear on sun-exposed areas of the body.
Symptoms
The main symptom of SCLE is the presence of skin lesions that are red and scaly. These lesions typically appear on sun-exposed areas of the body such as the face, neck, and arms. Other symptoms may include fatigue, joint pain, and fever.
Causes
The exact cause of SCLE is unknown, but it is believed to be an autoimmune disorder, where the body's immune system attacks its own cells. It is also associated with genetic factors and environmental triggers such as sunlight and certain medications.
Diagnosis
Diagnosis of SCLE is based on the presence of characteristic skin lesions, a positive ANA (Antinuclear Antibody) Test, and the exclusion of other conditions that can cause similar skin lesions. A skin biopsy may also be performed for confirmation.
Treatment
Treatment for SCLE primarily involves avoiding sun exposure and the use of sunscreens. Medications such as hydroxychloroquine and corticosteroids may also be used to manage symptoms.
