Symptoms of plaque psoriasis include dry, raised or red skin lesions, also called plaques, according to the Mayo Clinic. Typically, the plaques are covered with silvery scales. The plaques may be painful, irritating or itchy. Plaques may appear anywhere on the body, including on the genitals and inside the mouth.
Plaque psoriasis is the most common form of psoriasis, notes the Mayo Clinic. An individual suffering from this type of psoriasis can have many plaques all over the body, or just a few scattered skin lesions. These patches typically appear on the knees, elbows, low back or scalp, according to the National Psoriasis Foundation. Many times these plaques can crack, bleed or cause severe pain, if not treated.
The symptoms of plaque psoriasis can appear in cycles, and flare-ups may be caused by a number of factors, according to WebMD. Stress, issues that compromise the immune system, injury or even too much sun can cause psoriasis flare-ups. The symptoms of mild plaque psoriasis are similar to other skin conditions or medical reactions, so those experiencing symptoms should visit a medical professional for an official diagnosis.
Depending on the individual, psoriasis can be mild, moderate or severe, states the National Psoriasis Foundation. Both genetics and the immune system can play a role in how this condition develops. Many times, psoriasis is associated with other health conditions such as depressions, heart disease or diabetes.
