WHAT ARE THE SIGNS AND SYMPTOMS? The lesions vary in appearance with the type of psoriasis. There are five types of psoriasis: Plaque, guttate, pustular, inverse, and erythrodermic. About 80% of people living with psoriasis have plaque psoriasis, also called “psoriasis vulgaris.” Plaque psoriasis causes patches of thick, scaly skin that may be white, silvery, or red. Called plaques, these patches can develop anywhere on the skin. The most common areas to find plaques are the elbows, knees, lower back, and scalp. Psoriasis can affect the nails. About 50% of people who develop psoriasis see changes in their fingernails and/or toenails. Psoriasis can affect the joints too. Smaller joints of the hand and joints of the knee and lower back can also get involved. If joint pain develops then it is important to see a dermatologists as early treatment can prevent joint deterioration. WHAT CAUSES PSORIASIS? A family history of psoriasis seems to increase the risk of developing psoriasis. It is important to know that a family history of psoriasis does not guarantee that someone will develop psoriasis.
