Psoriasis is a chronic autoimmune skin condition that can cause skin to be red, thick, scaly, and flaky.
There are five main types of psoriasis:
- Plaque Psoriasis
- The most common type of psoriasis, affecting up to 80% of patients
- Characterized by raised, inflamed, and scaly patches of skin that may also be itchy and painful (plaques) that can occur anywhere on the body
- Skin may be red with silvery white scales or may appear purple-ish, depending on a person’s skin type
- Plaques most often appear on the scalp, knees, elbows, and in or around the belly button and lower back, but can develop on any area of the body
- Inverse Psoriasis
- Affects 25% of people who have psoriasis
- Characterized by inflamed deep-red skin that is smooth and not scaly
- Develops in skin folds in the body such as the armpits, under breasts, the genital area, and buttocks
- Can cause severe itching and pain and that may be worsened by sweat and rubbing the affected areas
- Guttate Psoriasis
- Pustular Psoriasis
- Erythrodermic Psoriasis
- Rare, affects about 2% of people who have psoriasis
- Often affects almost the entire body and can be life-threatening
- Characterized by intense redness and shedding of skin layers in large sheets
- Other symptoms include:
- Severe itching and pain
- Changes in heart rate and temperature
- Dehydration
