Types of Psoriasis (Part 2)

Pustular Psoriasis:

Pustular psoriasis, characterized by pustules or whiteheads (non-infectious blisters) surrounded by red skin. The pus is made up of white blood cells. It is not an infection and is not contagious. Pustular psoriasis is less common and may occur in different parts of the body but often occurs on the hands and feet.

Erythrodermic psoriasis:

Erythrodermic psoriasis is a rare type of psoriasis and occurs in 3% of people with psoriasis during their lifetime. Erythrodermic psoriasis is a severe form of the disease and affects more than 75% of the skin surface. It is often associated with skin loss, hair loss, nail dystrophy, and general symptoms such as fever, chills, and nausea with heart failure. It is common in people with unstable plaque psoriasis.

Psoriasis is often diagnosed by clinical examination and based on symptoms, and there is no blood test to diagnose it, although some tests are sometimes necessary to find the cause of the flare-up. However, in suspected cases, a skin biopsy may be used. Symptoms of psoriasis can vary from person to person and include one or more of the following:

1. 1. Red plaques on the skin covered with silver scales
   2. Dry and cracked skin that may bleed
   3. Itching and burning in parts of the skin
   4. Thick nails with pitting
   5. Swollen and stiff joints
