Lupus is a complex autoimmune disease that can affect various organs and systems in the body, including the skin. PatientsLikeMe has covered lupus extensively. Lupus flares, how it manifests in men vs. women, hair loss and bone density. These are just a few of the topics we've covered. Skin health, however, is not an area we have covered. How can lupus lead to a rash? PLM has the answers.
These rashes are a common manifestation of lupus, and they can vary widely in appearance and severity. Here's an overview of some of the common skin rashes associated with lupus.
Rashes
- Malar Rash (Butterfly Rash):
- This is one of the most classic and recognizable lupus rashes. It appears as a red or purplish rash that spreads across the cheeks and nose, resembling the shape of a butterfly. It can be flat or slightly raised and is often sensitive to sunlight.
- Discoid Rash:
- Discoid lupus erythematosus (DLE) is a chronic skin condition characterized by the presence of disc-shaped, scaly lesions. These lesions can cause scarring and pigment changes over time. Discoid rashes typically occur on the face, scalp, and ears but can also affect other areas of the body.
- Photosensitivity:
- People with lupus often experience increased sensitivity to sunlight, leading to a rash and skin lesions when exposed to UV rays. These rashes can be widespread or localized, and they may appear as redness, itching, or hives.
- Subacute Cutaneous Lupus Erythematosus (SCLE):
- SCLE presents as non-scarring, red, and coin-shaped lesions on areas of the skin exposed to sunlight. Unlike discoid lupus, SCLE lesions are not as thick or scaly, and they are often more widespread, affecting the shoulders, upper back, chest, and arms.
- Vasculitis:
- Lupus vasculitis can cause inflammation of blood vessels in the skin, leading to the development of purpura (small purple or red spots), petechiae (small red or purple dots), and ulcers. These skin manifestations are often associated with more severe systemic lupus erythematosus (SLE).
- Bullous Lupus Erythematosus:
- This rare form of lupus causes blistering lesions on the skin, similar to those seen in conditions like pemphigus or bullous pemphigoid. These blisters can be localized or widespread and are typically not associated with scarring.
Getting Treatment
It's important to note that lupus can affect individuals differently, and not everyone with lupus will experience the same skin symptoms. How these manifest may may change over time, and new rashes can develop. If you suspect you have lupus or experience any skin changes, it's crucial to consult with a healthcare professional for a proper diagnosis and appropriate management.
