Signs of Psoriasis

Description

A common skin condition that causes skin redness and irritation. It is a persistent disease, and the symptoms can vary widely from a mild irritation to a disabling disease. Psoriasis causes thick, red skin with flaky, silver-white patches called scales. The cause of the disorder is an over active immune system that attacks the normal skin. Certain triggers can make the symptoms worse such as infections, skin injury, stress, cold weather, smoking, alcohol use, and certain medications. The disease tends to run in families. Some patients also have arthritis associated with the disease.

Symptoms

Irritated red patches of skin most often found on the elbows, knees, and trunk, but can be anywhere on the body. Many times the skin becomes dry and covered with silver flakes (scales), and the affected skin becomes thickened. The nails become thickened and pitted. Some patient experience joint pain.

Tests

A history and physical exam will be performed. The diagnosis is usually made by simply looking at the skin. At times a skin biopsy will be done.

Treatment

The goal of therapy is to control the symptoms and prevent secondary infections. Treatment includes: topical steroids, topical vitamin D preparations, topical anthralin, topical retinoids, topical salicylic acid, coal tar, moisturizers, phototherapy, oral retinoids, oral methotrexate, oral cyclosporine, oral hydroyurea, and oral immunomodulator drugs (etanercept/Embrel, infliximab/Remicaide). If the rash is extensive hospitalization may be required. Antibiotics will be administered for secondary infections. For more information contact: Natioanl Psoriasis Foundation (800)723-9166
