Psoriasis: Symptoms, Pictures, Causes, and Treatments

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 theNational Psoriasis Foundation. If you have psoriasis, your skin cells grow faster than normal.

Newly diagnosed with psoriasis? Long-time patients have some empowering words for you

The body naturally develops new skin cells every month to replace skin that sheds or flakes off. With psoriasis, new skin cells form within days rather than weeks. This rapid growth causes dead skin cells to accumulate on the skins surface, resulting in thick patches of red, dry, and itchy skin.

Psoriasis is a chronic condition, but symptoms may improve over time.

Psoriasis can occur on the scalp, nails, and joints. In the United States, about 7.5 million people have psoriasis, according to the American Academy of Dermatology (AAD). The five types of psoriasis include the following.

This common form of psoriasis causes raised, red patches on the skin. Skin patches can be itchy and painful.

This type of psoriasis can start in childhood or young adulthood.

This type of psoriasis causes red lesions in body folds.

This type causes white blisters and red skin.

This rare inflammatory type of psoriasis can develop over the entire body. Symptoms include widespread redness, pain, and severe itching.

What Is Psoriasis?

The symptoms of psoriasis vary depending on the type you have. Some common symptoms for plaque psoriasis -- the most common variety of the condition -- include:

Psoriasis can also be associated with psoriatic arthritis, which leads to pain and swelling in the joints. The National Psoriasis Foundation estimates that between 10% to 30% of people with psoriasis also have psoriatic arthritis.

Other forms of psoriasis include:

Pustular psoriasis , characterized by red and scaly skin on the palms of the hands and/or feet with tiny pustules

Guttate psoriasis, which often starts in childhood or young adulthood, is characterized by small, red spots, mainly on the torso and limbs. Triggers may be respiratory infections, strep throat, tonsillitis, stress, injury to the skin, and use of anti-malarial and beta-blocker medications.

Inverse psoriasis, characterized by bright red, shiny lesions that appear in skin folds, such as the armpits, groin area, and under the breasts

Erythrodermic psoriasis, characterized by periodic, fiery redness of the skin and shedding of scales in sheets; this form of psoriasis, triggered by withdrawal from a systemic psoriasis treatment, severe sunburn, infection, and certain medications, requires immediate medical treatment, because it can lead to severe illness.

People who suffer from psoriasis know that this uncomfortable and at times disfiguring skin disease can be difficult and frustrating to treat. The condition comes and goes in cycles of remissions and flare-ups over a lifetime. While there are medications and other therapies that can help to clear up the patches of red, scaly, thickened skin that are the hallmark of psoriasis, there is no cure.

Psoriasis: Symptoms, Treatment, Diet and Medications

Psoriasis Psoriasis Overview

Psoriasis is a common and chronic incurable but treatable skin disorder. Plaque psoriasis is the most common form and appears as elevated plaques of red skin covered with silvery scale that may itch or burn. The involved areas are usually found on the arms, legs, trunk, or scalp but may be found on any part of the skin. The most typical areas are the knees, elbows, and lower back.

Factors such as smoking, sunburn, alcoholism, and HIV infection may prolong the severity and extent of the condition.

A significantpercentage of people with plaque psoriasis also have psoriatic arthritis. Individuals with psoriatic arthritis have inflammation in their joints and may have other arthritic symptoms. Sometimes plaque psoriasis can evolve into more inflammatory disease, such as pustular psoriasis or erythrodermic psoriasis. In pustular psoriasis, the red areas on the skin contain small blisters filled with pus. In erythrodermic psoriasis, extensive areas of red and scaling skin are present.

Psoriasis affects children and adults. Men and woman are affected equally. Females develop plaque psoriasis earlier in life than males. The first peak occurrence of plaque psoriasis is in people 16-22 years of age. The second peak is in people 57-60 years of age.

Psoriasis can affect all races. Studies have shown that more people in western European and Scandinavian populations have psoriasis than those in other population groups.

Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales.

These patches normally appear on your elbows, knees, scalp and lower back, but can appear anywhere on your body.Most people are only affected with small patches. In some cases, the patches can be itchy or sore.

Psoriasis affects around 2% of people in the UK. It can start at any age, but most often develops in adults under 35 years old. The condition affects men and women equally.

The severity of psoriasis varies greatly from person to person. For some people it's just a minor irritation, but for others it can havea major impact on their quality of life.

Psoriasis is a long-lasting (chronic) disease that usually involves periods when you have no symptoms ormild symptoms, followed by periods when symptoms are more severe.

Read more about the symptoms of psoriasis.

People with psoriasis have anincreased production of skin cells.

Skin cells are normallymade and replaced every three to four weeks, but in psoriasis this process only lasts about three to seven days. The resulting build-up of skin cells is what creates the patches associated with psoriasis.

Although the process isn't fully understood, it's thoughtto be related to a problem with the immune system. The immune systemis your body's defence against disease and infection, but for people with psoriasis, it attacks healthy skin cells by mistake.

Psoriasis can run in families,although the exact role that genetics plays in causing psoriasis is unclear.

Questions and Answers About Psoriasis

October 2013

This publication contains general information about psoriasis. It describes what psoriasis is, what causes it, and what the treatment options are. If you have further questions after reading this publication, you may wish to discuss them with your doctor.

Psoriasis is a chronic (long-lasting) skin disease of scaling and inflammation that affects greater than 3 percent of the U.S. population, or more than 5 million adults. Although the disease occurs in all age groups, it primarily affects adults. It appears about equally in males and females.

Psoriasis occurs when skin cells quickly rise from their origin below the surface of the skin and pile up on the surface before they have a chance to mature. Usually this movement (also called turnover) takes about a month, but in psoriasis it may occur in only a few days.

In its typical form, psoriasis results in patches of thick, red (inflamed) skin covered with silvery scales. These patches, which are sometimes referred to as plaques, usually itch or feel sore. They most often occur on the elbows, knees, other parts of the legs, scalp, lower back, face, palms, and soles of the feet, but they can occur on skin anywhere on the body. The disease may also affect the fingernails, the toenails, and the soft tissues of the genitals, and inside the mouth. Although it is not unusual for the skin around affected joints to crack, some people with psoriasis experience joint inflammation that produces symptoms of arthritis. This condition is called psoriatic arthritis.

Individuals with psoriasis may experience significant physical discomfort and some disability. Itching and pain can interfere with basic functions, such as self-care, walking, and sleep. Plaques on hands and feet can prevent individuals from working at certain occupations, playing some sports, and caring for family members or a home. The frequency of medical care is costly and can interfere with an employment or school schedule. People with moderate to severe psoriasis may feel self-conscious about their appearance and have a poor self-image that stems from fear of public rejection and concerns about intimate relationships. Psychological distress can lead to significant depression and social isolation.

Psoriasis is a skin disorder driven by the immune system, especially involving a type of white blood cell called a T cell. Normally, T cells help protect the body against infection and disease. In the case of psoriasis, T cells are put into action by mistake and become so active that they trigger other immune responses, which lead to inflammation and to rapid turnover of skin cells.

In many cases, there is a family history of psoriasis. Researchers have studied a large number of families affected by psoriasis and identified genes linked to the disease. Genes govern every bodily function and determine the inherited traits passed from parent to child.

People with psoriasis may notice that there are times when their skin worsens, called flares, then improves. Conditions that may cause flares include infections, stress, and changes in climate that dry the skin. Also, certain medicines, including beta-blockers, which are prescribed for high blood pressure, and lithium may trigger an outbreak or worsen the disease. Sometimes people who have psoriasis notice that lesions will appear where the skin has experienced trauma. The trauma could be from a cut, scratch, sunburn, or infection.

Occasionally, doctors may find it difficult to diagnose psoriasis, because it often looks like other skin diseases. It may be necessary to confirm a diagnosis by examining a small skin sample under a microscope.
