Sometimes it’s thinner, sometimes thicker. The plaque will actually be larger than half an inch in diameter. The changes at a plaque psoriasis consists of those coin-shaped rashes, on a small or large part of the body, that forms irregular patterns on the skin. A typical plaque psoriasis means, that on the body there is a variable number of skin changes with clear boundary between what is healthy versus sick skin. Some skin changes are smaller, other larger. They are located on the typical places such as the scalp, elbows, knees and lower back. There is usually a symmetrical distribution on the body as regards to the left and right part of the body. The scalp is a common site for psoriasis. In one third of patients the scalp is the first place where psoriasis is found in, and it can often be misinterpreted in the beginning as a dandruff eczema (seborroic eczema). It is estimated that around 25 percent have psoriasis on the scalp.
