Psoriasis is a common skin condition characterized by thick, red or irritated skin, as well as psoriatic plaques - flaky, silver-white patches. Psoriasis can be localized on various parts of the body, including, but not limited to, the groin, armpit, ear, scalp, arms, legs and nails. Excessive skin production causes the psoriatic plaques to appear, the accumulation of which becomes inflamed. There is no cure for psoriasis, but there are many treatments for the management of the skin disease.
