What Do You Want to Know About Psoriasis? Psoriasis is a common skin condition that can affect anyone, although it’s more common in people between the ages of 15 and 35, according to the National Psoriasis Foundation. Know where to go. Primarily, such complications occur in relation to a severe, extensive form of psoriasis, such as generalized pustular psoriasis or erythrodermic psoriasis, where large areas of skin are shed. Psoriasis is a chronic skin disorder that causes areas of thickened, inflamed, red skin, often covered with silvery scales. The middle layer is the dermis; this is the layer where collagen and blood vessels are found.
Postular (or pustular) psoriasis can either be concentrated in one area, such as the hands or feet, or spread over the body. The patches where it occurs are covered with small, pus-filled bumps that are often tender and painful.
