Psoriasis is a chronic skin condition that results in inflammation of the skin throughout the body. It is an autoimmune disease in which the cells of the body act against themselves and begin growing rapidly in an unhealthy manner. As a result of this, the cells start building up over the surface of the skin instead of falling off, leading to scaly patches. This can sometimes cause redness, itchiness, or pain.

Here are five different types of Psoriasis observed in people.

• Plaque Psoriasis
  This is one of the most common types of Psoriasis and is said to be observed in almost 80% of Psoriasis patients. In this condition, the skin develops significant red patches, which are often covered by silver or white scaly layers. Also known as Psoriasis Vulgaris, in this type of Psoriasis, such patches are usually 1 to 10 centimeters wide and are seen on elbows, knees, scalp, or the lower back.
• Guttate Psoriasis
  After Plaque Psoriasis, the second most common type is known as guttate Psoriasis. In this type, the person develops small, drop-shaped red spots on the skin that are caused by inflammation. It is commonly observed on the face and the scalp and can also be found on the arms, legs, and torso.
• Inverse Psoriasis
  In Inverse Psoriasis, also known as Flexural Psoriasis, the inflammation of the skin is often observed specifically in the folds of the skin. This may include the armpits, under the breasts, in the buttocks, or the groin area. As a result of sweat and dirt settling in these crevices, this condition results in a lot of itching and discomfort.
• Pustular Psoriasis
  Pustular Psoriasis, which is observed in only 3% of people suffering from Psoriasis is a severe condition as compared to the other types. The skin is covered in white, cystic bumps, which are known as pustules. These pustules are often accompanied by red skin surrounding them and can sometimes merge together to develop scaly layers. The pus that is in the pustules is noninfectious but can sometimes cause flu-like symptoms.
• Erythrodermic Psoriasis
  Considered to be one of the rarest types of Psoriasis, Erythrodermic Psoriasis is observed in just 2% of patients. It is also known as exfoliative Psoriasis and is known to cover large patches of the skin. It is considered to be a medical emergency, and patients with symptoms of exfoliative Psoriasis need to seek medical attention immediately.
