  • There are actually five types of psoriasis — all with different symptoms and effects, but are equally irritating
  • Erythrodermic psoriasis can result in protein and fluid loss, severe illness and even life-threatening infections, pneumonia and congestive heart failure

Did you know that psoriasis is not just one type of skin disease? There are actually five types1 of psoriasis — all with different symptoms and effects, but equally irritating.

Plaque Psoriasis

Patients with plaque psoriasis notice the development of raised, red and inflamed lesions covered by a silvery and white scale on their elbows, knees, scalp and lower back. This is actually the most common type of psoriasis, with 80 percent of patients experiencing this condition.2

Inverse Psoriasis

This type of psoriasis is characterized by the appearance of red lesions that may look smooth and shiny, sans a silvery and white scale. The lesions are typically found in the armpits, groin, buttocks, under the breasts and on skin folds around the genitals.3

Two risk factors that could prompt inverse psoriasis are having deep skin folds and being overweight, so people who fall under these categories should be aware. It is also important that irritation from rubbing and sweating is avoided, since this could make the lesions present in skin folds and tender areas worse.4

Erythrodermic Psoriasis

Unlike the first two types of psoriasis, erythrodermic psoriasis is inflammatory, hence it can lead to large parts of your body turning into a bright red color. An imbalance in your body’s chemistry is said to be the main cause of this type of psoriasis.5

However, don’t count out these triggers emphasized by the National Psoriasis Foundation:6

Abrupt withdrawal of systemic treatment

Severe sunburn

Allergic-drug induced rash that could result in the Koebner phenomenon (tendency for psoriasis to appear in locations of skin injuries)

Use of systemic steroids or cortisone


Emotional stress


The people who are most prone to erythrodermic psoriasis are those who experience unstable plaque psoriasis, wherein the lesions aren’t clearly well-defined. Aside from massive reddening on your body, this condition exhibits the following symptoms:7

Exfoliation (shedding of the skin)

Severe itching and pain

Edema or swelling because of fluid retention, especially around the ankles

Difficulty of the body in regulating temperature, resulting in shivering

Erythrodermic psoriasis can result in protein and fluid loss, severe illness and even life-threatening infections, pneumonia and congestive heart failure.8

Guttate Psoriasis

If you have this type of psoriasis, you might have already noticed the disease starting out while you were a child or young adult. Guttate psoriasis is characterized by small, red and individual spots on the skin, but they are not normally as thick or crusty compared to lesions among plaque psoriasis patients.9 Certain triggers can cause the development of these lesions, such as:10

Bacterial or viral infections that include upper respiratory and streptococcal11 infections



Skin injuries such as cuts, burns and insect bites

Drugs such as anti-malarials, lithium and beta-blockers

Excessive alcohol intake

Pustular Psoriasis

This type of psoriasis is quite different from the others, because as the name implies, the patients will develop white blisters, or blisters containing noninfectious pus, surrounded by red skin. These pustules tend to appear either in certain parts of the body, such as your hands and feet, or over most your body.12 You can be affected with any of these three types of pustular psoriasis:13

Von Zumbusch

Palmoplantar pustolosis (PPP)


Pustular psoriasis typically imitates a cycle wherein reddening of the skin is followed by the development of pustules and scaling. However, it’s not an infection, nor is it contagious. This type of psoriasis is also uncommon, and only makes up a mere 5 percent of all psoriasis cases. Pustular psoriasis also affects adults more than children.14
