Psoriasis is a medical disorder of the skin that normally consists of red patches covered by silvery-white scales particularly around the elbows, knees, trunk, and scalp.
Psoriasis is a skin disease that produces scaling and inflammation (pain, swelling, heat, redness).
Skin cells normally grow deep in the skin and slowly rise to the surface.
This cell turnover normally takes about a month.
With psoriasis, it can happen in just a few days because the cells rise too fast to the surface and pile up on the skin.
Dead skin cells build up on the skin's surface

2. Guttate psoriasis (small, red spots on the skin),
3. Pustular psoriasis (white pustules that are surrounded by red irritated skin),
4. Inverse psoriasis (smooth, red lesions form in skin folds)
5. Erythrodermic psoriasis (widespread redness, severe itching, and pain)
Sometimes, a skin biopsy is done to rule out other possible conditions.
3 treatment options are available:
1. Topical medications (such as steroid and tar lotion),
2. Systemic therapy e.g. methotrexate, cyclosporins
3. Phototherapy, which uses ultraviolet light to treat psoriasis.
One treatment, called PUVA, uses a combination of a drug called psoralen that makes skin more sensitive to light and ultraviolet A light.
Psoriasis can be a life-long condition that can be ...
