The most common form, plaque psoriasis causes dry, raised, red skin lesions (plaques) covered with silvery scales. The sores are covered by a fine scale and aren’t as thick as typical plaques are. In addition to inflamed, scaly skin, psoriatic arthritis causes pitted, discolored nails and the swollen, painful joints that are typical of arthritis. Although the disease usually isn’t as crippling as other forms of arthritis, it can cause stiffness and progressive joint damage that in the most serious cases may lead to permanent deformity. These patches may be referred to as papules or plaques and most often affect the scalp, elbows, knees, hands, feet and/or lower back. However, in rare cases, two different forms of psoriasis can affect one person at the same type. When the papules grow and connect together they produce dry, scaly, rough, red plaques over large areas of the skin. Thick scalp plaques may be more difficult to treat.

Dermatologic biopsy: Can be used to make the diagnosis when some cases of psoriasis are difficult to recognize (eg, pustular forms). Symptoms: Reoccurring outbreaks of distinct red areas of skin, covered by silvery-white flaky skin. There are five clinical subtypes, each with unique signs and symptoms, but is generally characterized by thick, red skin with overlying silver-white patches called scales, referred to as psoriatic plaques.

This is the most common form of the disease, accounting for about 80 to 90 percent of cases.

While this can be confused with plaque-type psoriasis, the scales of psoriasis tend to be thicker and the lesions have much more clearly defined borders. The most common form, plaque psoriasis causes dry, raised, red skin lesions (plaques) covered with silvery scales. Although the disease usually isn’t as crippling as other forms of arthritis, it can cause stiffness and progressive joint damage that in the most serious cases may lead to permanent deformity. Dead skin and white blood cells can’t slough off quickly enough and build up in thick, scaly patches on the skin’s surface. Related to vitamin A, this group of drugs may reduce the production of skin cells if you have severe psoriasis that doesn’t respond to other therapies. Most cases of psoriasis are treated with medications that are placed directly on the skin or scalp:. Psoriasis patches can range from a few spots of dandruff-like scaling to major eruptions that cover large areas. Mild cases of psoriasis may be a nuisance; more-severe cases can be painful, disfiguring and disabling. Severe cases of psoriasis may lead to secondary infections as well as fluid loss resulting in poor blood flow. Furthermore, patients undergoing treatments for severe psoriasis may experience adverse side effects from the medications used.

Psoriasis: Practice Essentials, Background, Pathophysiology
Extensive skin redness results in scales being shed of in large sheets, which causes severe pain and discomfort. Studies indicate that the most cases of Psoriasis may be inherited, due to the incidence of Psoriasis among the families of affected individuals. Salicylic acid is the most effective of the known keratolytic compounds, and is most beneficial in extremely thick or scaly psoriatic plaques. The typical morphology is a 1-cm or larger well-demarcated red plaque surmounted by white or silvery scales. (Fig.1) The lesions can occur anywhere, but the most commonly involved areas are the elbows, knees, scalp, sacrum, navel, intergluteal cleft, and genitalia. Pustular psoriasis accounts for about 2 of cases and may be localized to palms and soles, (Fig. In some cases, the rash does not form blisters, but has an appearance much like urticaria (hives). They are most common on the torso, but can also appear on the face (where they are potentially hazardous to vision) or other parts of the body. The scaly patches caused by psoriasis, called psoriatic plaques or lesions, are areas of excessive skin production and inflammation. Symptoms include, itching in groin, thigh skin folds, or anus, with red, raised, scaly patches that may blister and ooze.

Places where the skin is thick, such as the soles of the feet and the palms of the hands, are less sensitive to the sap than areas where the skin is thinner. The scaly patches commonly caused by psoriasis, called psoriatic plaques, are areas of inflammation and excessive skin production.

Psoriasis is a long-term skin condition characterised by red, scaly patches on the skin, itchiness and skin flaking. Psoriasis occurs when white blood cells produce a number of damaging chemicals in the skin, as if fighting an infection or healing a wound. In turn, this immune response is thought to trigger changes that cause the skin cells to multiply at an unusually rapid rate. These spots are usually not as thick as the patches that develop in plaque psoriasis.
