Psoriasis is a chronic inflammatory skin disorder which is classified as immune-mediated; this means it is a result of abnormal activity of the body’s immune cells. This condition can begin at any age and tends to be life-long with fluctuations in severity.
Psoriasis involves red, scaly plaque-like areas with well-defined borders. The scales are often a silvery white colour. The most common sites for psoriasis to appear include the elbows, knees and scalp. Symptoms of psoriasis include a mild itch that can also be severe for some individuals. Skin cracks, also known as fissures, may occur as a result of frequent itching. Once psoriasis plaques clear, you may notice your skin has brown or pale marks which usually fade after a few months.
Psoriasis is diagnosed mainly by its clinical features and its appearance on one’s body, however if necessary, a small skin biopsy can be done as well for confirmation. Treatments can include topical therapies such as creams and ointments for mild cases and oral medications or injections if more severe.
