Lupus erythematosus (LE) is an autoimmune disease that can affect various organs in the body, including the skin. Cutaneous symptoms are common in lupus erythematosus, and they can range from mild to severe. In this blog post, we will discuss the different cutaneous symptoms that can occur in lupus erythematosus.
The cutaneous symptoms in lupus erythematosus can be divided into acute cutaneous lupus erythematosus (ACLE), subacute cutaneous lupus erythematosus (SCLE), and chronic cutaneous lupus erythematosus (CCLE).
Acute Cutaneous Lupus Erythematosus (ACLE)
ACLE is characterized by the presence of a butterfly rash on the face. The rash typically appears on the cheeks and bridge of the nose and has a butterfly-like shape. The rash may be red or pink and may be accompanied by a burning or itching sensation. In some cases, the rash may also be accompanied by a fever, fatigue, and joint pain.
Subacute Cutaneous Lupus Erythematosus (SCLE)
SCLE is characterized by the presence of scaly, red patches on the skin. The patches may be round or oval in shape and may appear on the chest, back, shoulders, and upper arms. The patches may also be accompanied by a rash on the face, neck, and arms. The rash may be itchy or painful and may be accompanied by fatigue, joint pain, and fever.
Chronic Cutaneous Lupus Erythematosus (CCLE)
CCLE is characterized by the presence of skin lesions that are thick, scaly, and raised. The lesions may appear on the face, neck, scalp, and ears. The lesions may also be accompanied by a rash on the arms, legs, and trunk. The rash may be itchy or painful and may be accompanied by fatigue, joint pain, and fever.
Other Cutaneous Symptoms
Other cutaneous symptoms that can occur in lupus erythematosus include hair loss, mouth sores, and nail changes. Hair loss may occur in patches or be diffuse, and it may be temporary or permanent. Mouth sores may be painful or painless and may appear on the roof of the mouth, gums, or tongue. Nail changes may include thickening, discoloration, or ridging of the nails.
Laboratory Investigations
Laboratory investigations are an important part of the diagnosis and management of lupus erythematosus. Blood tests can be used to measure the level of antibodies in the blood, including antinuclear antibodies (ANA), anti-double-stranded DNA (anti-dsDNA) antibodies, and anti-Smith (anti-Sm) antibodies. These antibodies are commonly found in people with lupus erythematosus.
In addition to blood tests, skin biopsies may also be performed to confirm the diagnosis of lupus erythematosus. A skin biopsy involves removing a small sample of skin tissue and examining it under a microscope.
Conclusion
Cutaneous symptoms are common in lupus erythematosus and can range from mild to severe. The cutaneous symptoms can be divided into acute, subacute, and chronic cutaneous lupus erythematosus. Other cutaneous symptoms may include hair loss, mouth sores, and nail changes. Laboratory investigations are an important part of the diagnosis and management of lupus erythematosus. If you suspect that you have lupus erythematosus, it is important to see your healthcare provider for an accurate diagnosis and appropriate treatment.
