Dermatitis associated to Psoriasis

Dermatitis and Psoriasis

Skin Cancer and Psoriasis

Research suggests that psoriasis is rarely seen in people with sun-related skin cancers like melanoma or solar keratosis. However, certain psoriasis treatments, such as ultraviolet rays, methotrexate, X-rays, and corticosteroids, may increase the risk of skin cancer for some individuals.

Types of Dermatitis and Their Connection to Psoriasis

1. Seborrheic dermatitis can look similar to psoriasis, especially on the scalp and joints, but it usually has a yellowish, greasy texture and may cause some hair loss. Psoriasis lesions, by contrast, are more easily felt when touched.

2. Atopic dermatitis (also known as eczema) rarely coexists with psoriasis. In a study, only 3 out of 1,170 patients with atopic dermatitis also had psoriasis. If there’s doubt, a dermatologist can perform a biopsy to distinguish between the two.

3. Contact dermatitis occurs when the skin reacts to an allergen, leading to redness and itching. In some cases, psoriasis lesions may appear after exposure to an allergen, indicating a possible link between contact dermatitis and psoriasis.
