Lupus Erythematosus vs. Photosensitivity Dermatitis
Similarities:
- Both involve photosensitivity, where exposure to sunlight triggers skin reactions such as redness, inflammation, or rash.
- Sun protection is essential for both conditions, including sunscreen and sun avoidance.
- Both conditions require medical management to prevent flare-ups.
Differences:
- Lupus Erythematosus is an autoimmune disorder that affects not only the skin but also other organs, and it can cause a characteristic butterfly-shaped rash on the face after sun exposure.
- Photosensitivity Dermatitis is a skin reaction to UV light caused by external factors such as medications or plant exposure, and it does not affect internal organs.
- Lupus often involves systemic symptoms, while photosensitivity dermatitis is localized to the skin.
