What is Psoriasis and there symptom

A condition in which skin cells accumulate and form dry, itchy scales and patches.
Psoriasis is believed to be a problem of the immune system. Triggers include infections, stress, and a cold.

What is Psoriasis and there symptom

The most common symptom is a skin rash, but sometimes the rash affects the nails or joints.
The treatment aims to remove scales and prevent skin cells from growing as fast. Topical ointments, light therapy, and medications can offer relief.

Psoriasis typically affects the outside of the elbows, knees or scalp, though it can appear on any location. Some people report that psoriasis is itchy, burns and stings. Psoriasis is associated with other serious health conditions, such as diabetes, heart disease and depression.

If you develop a rash that doesn't go away with an over-the-counter medication, you should consider contacting your doctor.

How do I get psoriasis?

While scientists don't know exactly what causes psoriasis, we do know that the immune system and genetics play a role in its development. Something usually causes psoriasis to flare up. The skin cells in people with psoriasis grow at an abnormally fast rate, causing the accumulation of psoriasis lesions.

Men and women develop psoriasis at equal rates. Psoriasis also occurs in all racial groups, but at variable rates. About 1.9 percent of African Americans have psoriasis, compared to 3.6 percent of Caucasians. According to current studies, more than 8 million Americans have psoriasis. See additional statistics on psoriatic disease.

Psoriasis often develops between the ages of 15 and 35, but it can develop at any age. About 10 to 15 percent of people with psoriasis get it before age 10. Some babies have psoriasis, although this is considered rare.

Psoriasis is not contagious. It is not something you can "catch" or that others can catch from you. Psoriasis lesions are not infectious.

How is psoriasis diagnosed?

There are no blood tests or special tools to diagnose psoriasis. A dermatologist (doctor specializing in skin conditions) or other health care provider usually examines the affected skin and determines if it is psoriasis.

Your doctor may take a piece of the affected skin (a biopsy) and examine it under a microscope. When biopsied, skin with psoriasis appears thicker and more inflamed compared to skin with eczema.

Your doctor will also want to learn about your family history. About a third of people with psoriasis have a family member with the disease, according to dermatologist Dr. Paul Yamauchi of the Institute of Dermatology and Skin Care in Santa Monica, California.

What type of psoriasis do I have?

There are five types of psoriasis. Learning more about your type of psoriasis will help you determine the best treatment for you.

Plaque psoriasis

Plaque psoriasis is the most common form of the disease and appears as raised red patches covered with a silvery white buildup of dead cells. These patches or plaques appear most often on the scalp, knees, elbows, and lower back. They often cause itching and pain, and can crack and bleed.

Guttate psoriasis contagious

Guttate psoriasis [GUH-tate] is a form of psoriasis that appears as small, dot-like lesions. Guttate psoriasis often begins in childhood or ad*lthood and can be triggered by a strep infection. This is the second most common type of psoriasis, after plaque psoriasis. About 10 percent of people who get psoriasis develop guttate psoriasis.


Reverse psoriasis appears as very red lesions in the folds of the body, such as behind the knee, under the arm, or in the groin. It may appear smooth and shiny. Many people have other types of psoriasis on other parts of the body at the same time.

Pustular psoriasis on hands

Pustular psoriasis [PUHS-choo-lar] is characterized by white pustules (non-infectious pus blisters) surrounded by red skin. The pus consists of white blood cells. It is not an infection, nor is it contagious. Pustular psoriasis can occur anywhere on the body, but it most often occurs on the hands or feet.


Erythrodermic psoriasis [eh-REETH-ro-der-mik] is a particularly severe form of psoriasis that leads to intense and intense redness in most of the body. It can cause severe itching and pain, causing the skin to peel off on sheets. It is rare, it occurs in 3 percent of people who have psoriasis during their lifetime. It generally appears in people who have unstable plaque psoriasis.

People who have an outbreak of erythrodermic psoriasis should see a doctor immediately. This form of psoriasis can be fatal.

Where does psoriasis appear?

Psoriasis can appear anywhere: on the eyelids, ears, mouth and lips, skin folds, hands and feet, and nails. The skin at each of these sites is different and requires different treatments.

Light therapy or topical treatments are often used when psoriasis is limited to a specific part of the body. However, doctors may prescribe oral or injectable medications if psoriasis is widespread or if it greatly affects your quality of life. There are effective treatments, no matter where your psoriasis is located.

Common areas of the body where psoriasis symptoms occur.


Psoriasis of the scalp can be very mild, with fine, light scales. It can also be very serious with thick plaques and crusts that cover the entire scalp. Psoriasis can spread beyond the hairline to the forehead, back of the neck, and around the ears.

Facial psoriasis most often affects the eyebrows, the skin between the nose and the upper lip, the upper forehead and the hairline. Psoriasis on and around the face should be treated with care because the skin here is sensitive.

Hands, feet and nails

Treat sudden outbreaks of psoriasis on the hands and feet promptly and carefully. In some cases, cracks, blisters, and swelling accompany the outbreaks. Nail changes occur in up to 50 percent of people with psoriasis and in at least 80 percent of people with psoriatic arthritis.

Genital psoriasis

The most common type of psoriasis in the genital region is reverse psoriasis, but other forms of psoriasis may appear on the genitals, especially in men. Genital psoriasis requires careful treatment and care.

Skin folds

Reverse psoriasis can occur in the skin folds, such as the armpits and under the br**sts. This form of psoriasis is frequently irritated by rubbing and sweating.

How serious is my psoriasis?

Psoriasis can be mild, moderate, or severe. Your treatment options may depend on the severity of your psoriasis. The severity is based on the amount of your body affected by psoriasis. The entire hand (palm, fingers, and thumb) is about 1 percent of your body's surface.


One percent psoriasis coverage

However, the severity of psoriasis is also measured by how psoriasis affects a person's quality of life. For example, psoriasis can have a serious impact on daily activities, even if it involves a small area, such as the palms of the hands or the soles of the feet.

Will I develop psoriatic arthritis?

About 11 percent of those diagnosed with psoriasis have also been diagnosed with psoriatic arthritis. However, about 30 percent of people with psoriasis will eventually develop psoriatic arthritis.

Psoriatic arthritis can often go undiagnosed, particularly in its milder forms. However, treating psoriatic arthritis from the beginning is important to help prevent permanent joint damage. Find out more about psoriatic arthritis.

What about psoriasis in children?

Each year, approximately 20,000 children under the age of 10 are diagnosed with psoriasis. Sometimes it is misdiagnosed because it is mistaken for other skin conditions. Symptoms include pitting and discoloration of the nails, severe peeling of the scalp, diaper rash, or plaques similar to those of ad*lt psoriasis on the trunk and extremities. Psoriasis in infants is rare, but it does occur. Only close observation can determine if a baby has the disease.

If a parent has the disease, there is about a 10 percent chance that a child will get it. If both parents have psoriasis, the probability increases to 50 percent. No one can predict who will get psoriasis. Scientists now believe that at least 10 percent of the general population inherits one or more of the genes that create a predisposition to psoriasis. However, only 2 to 3 percent of the population develops the disease.

Some young people report the onset of psoriasis after an infection, particularly strep throat. One-third to one-half of all young people with psoriasis may experience an outbreak two to six weeks after an earache, pharyngitis, bronchitis, tonsillitis, or a respiratory infection. Areas of skin that have been injured or traumatized are occasionally sites of psoriasis, known as the "Koebner [keb-ner] phenomenon". However, not all people who have psoriasis develop it at the site of an injury.
