What skin conditions can look like psoriasis?

Lee A. Kaplan, MD
Dermatology
There are a variety of conditions that could cause white spots to appear on the skin, including allergies, infections and other autoimmune disorders. Some of the most common causes for white spots, besides psoriasis, include eczema and seborrheic dermatitis.

White patches or spots on the skin can also be a sign of a calcium or vitamin deficiency, particularly vitamins D and E. It's best to see your doctor if you notice dramatic changes or new irritations on your skin.

Other skin conditions can look like psoriasis, but they're not. For example, red, dry skin is often caused by infections, rosacea, and irritants. Seborrheic dermatitis can cause dandruff and crusty patches of skin that may be confused with scalp psoriasis. Other inflammatory skin conditions, including common atopic dermatitis (eczema), can also be mistaken for psoriasis.
