Dermatologist FAQ: What is Psoriasis?

Dermatologist FAQ: What is Psoriasis? | St. Louis, MissouriPsoriasis is not simply a “skin condition.” In reality, it develops underneath the skin. Psoriasis is a chronic or long-lasting condition of the immune system that can range from mild to severe. At times, it may be linked to diseases such as psoriatic arthritis, Type 2 diabetes, and cardiovascular disease.

Board certified dermatologist Dr. Jamie McGinness and Jackie McGinness, FNP (Nurse Practitioner) provide advanced skin care treatments to patients in Shiloh, IL; St. Louis, MO, and surrounding locations.


How Psoriasis Occurs

The psoriasis symptoms on the skin’s surface are only a part of the complete story. The body takes around 28 to 30 days to produce new skin cells and shed the old ones if the skin is healthy.

When an individual has plaque psoriasis, the immune system becomes hyperactive causing skin inflammation. This leads to the skin cells being produced faster than normal. The new skin cells are pushed to the skin’s surface in three to four days instead of the standard 28 to 30 days.

But the body cannot shed the new skin cells so rapidly. This causes old, dead skin cells to collect over each other as new skin cells are being produced at a rapid rate. This rapid generation of new skin cells causes the old ones to be pushed to the surface of the skin.

This leads to the development of red, itchy, thick, and flaky patches known as plaques. But the exact causes for the development of psoriasis are unknown.


Psoriasis Types

Many people are not aware that there are various forms of psoriasis. However, a person typically has one form of the condition at a time. Every type of psoriasis has distinct symptoms that can manifest on the skin in various ways.

It is vital to understand and share with other individuals that regardless of the location of psoriasis or what it looks like, it is not contagious.

Plaque Psoriasis

This type of psoriasis is characterized by raised, inflamed, red lesions that are covered by silvery white scales. Plaque psoriasis typically develops on the lower back, elbows, knees, and scalp. This is the most commonly occurring type of psoriasis, and 80 percent of all psoriasis patients have this form.

Guttate Psoriasis

Guttate psoriasis typically initiates in childhood or young adulthood. This type of psoriasis appears as tiny, pink individual spots on the legs, arms, and torso. These spots are usually not as thick as plaque lesions.  

Inverse Psoriasis

Inverse psoriasis occurs in sites such as the armpits, groin, under the breasts, and other skin folds around the buttocks and genitals. This type of psoriasis appears as bright-red lesions that are smooth and shiny.

Pustular Psoriasis

Pustular psoriasis usually develops in adults. It is characterized by the presence of blisters of noninfectious pus surrounded by red skin. It can be localized to particular body areas such as the feet or hands or may cover a substantial part of the body.  

Erythrodermic Psoriasis

This type of psoriasis is especially inflammatory and affects most of the body’s surface. It is characterized by the presence of extensive, periodic red skin and the shedding of scales in sheets.

Psoriasis and Joint Pain

In case a patient has psoriasis and experiences pain, stiffness, or swelling in and around their joints, they may be suffering from the symptoms of a condition associated with psoriasis, known as psoriatic arthritis.
