What are the 5 types of psoriatic arthritis?

In this article, we discuss the What are the 5 types of psoriatic arthritis. Psoriatic arthritis is an autoimmune disease in which the body attacks itself, causing joint pain and inflammation. There are several types of psoriatic arthritis; some types affect specific joints while others cause inflammation throughout the body, especially in areas that frequently hurt with psoriases like skin, nails, and scalp. Here are five types of psoriatic arthritis to know about when going through treatment.

What is psoriatic arthritis?

Psoriatic arthritis (PsA) is a kind of arthritis. This arthritis impacts individuals with the skin condition psoriasis. It’s estimated that PsA affects about 20 to 30 per cent of trusted sources of people with psoriasis.

Psa can also cause the affected joints. Then it becomes painful, stiff, and swollen. The condition is different for everyone. Symptoms can vary from mild to extreme and can affect only a few or several joints.

5 types of psoriatic arthritis

There are also 5 types of psoriatic arthritis:

  1. Asymmetric psoriatic arthritis
  2. Symmetric psoriatic arthritis
  3. Distal interphalangeal predominant psoriatic arthritis
  4. Spondylitis psoriatic arthritis
  5. Psoriatic arthritis mutilans
  1. Asymmetric psoriatic arthritis

Asymmetric psoriatic arthritis (also known as asymmetric oligoarthritis) is an uncommon form of psoriasis that affects only one joint, usually at a time. It’s characterized by sudden pain in one joint and then a gradual decrease in symptoms. It can be found anywhere but is most common in the knees and fingers. Asymmetric oligoarthritis may be associated with other autoimmune disorders such as Hashimoto’s thyroiditis or Sjogren’s syndrome. It is also more likely to affect people over 40 who have had diabetes for many years or smokers. Treatment includes nonsteroidal anti-inflammatory drugs and sometimes steroid injections to reduce inflammation and pain.


Different symptoms of asymmetric PsA can include:

  • Joints that are
  • Tender or painful
  • Swollen
  • Warm to the touch
  • Reduce the scope of motion in the manufactured joints
  • Morning joint stiffness
  • Redness of the fingers or toes
  • Bump and pain where tendons and ligaments attach to bone (enthesitis)
  • Nail modifications, like pitting, breaking, and splitting from the nail bed
  • Itchy, scaly skin patches
  • Fatigue
  • Eye problems like redness and uveitis
  1. Symmetric psoriatic arthritis

Symmetric Psoriatic Arthritis, also known as SpA, is a type of arthritis that affects joints symmetrically. It can affect any joint in your body but usually begins in the hands and feet. Patients with this form of arthritis may have inflammation or stiffness in their joints for long periods before it gets better. The pain can be mild to moderate with SpA, but it’s often worse at night or after physical activity. This type is less common than other forms, and there is no cure.


Psoriatic arthritis is a chronic inflammatory disorder that can occur in as many as 1 in 50 people with psoriasis. The disease usually develops after age 40 and will affect about 10% of all people with psoriasis. Psoriatic arthritis is an inflammatory arthropathy, including rheumatoid and ankylosing spondylitis. 

Psoriasis is an autoimmune disease that causes skin cells to grow too quickly, forming thick red patches on the skin. Around 20% of those with psoriasis will develop this form of arthritis. 

The symptoms are often symmetrical, affecting joints on both sides of the body simultaneously, but not necessarily symmetrically or equally.

  1. Distal interphalangeal predominant psoriatic arthritis

Distal interphalangeal predominant psoriatic arthritis is one of the five types of arthropathy. It mainly affects hands and feet but can also affect other joints such as knees, hips, and elbows. In this form, the inflammation usually starts in distal interphalangeal joints (the ones furthest from the body) but can sometimes start in proximal interphalangeal joints (the closest to the body). The first sign is often swelling or redness at these points. Other symptoms include pain and tenderness in these areas. In addition, joints may become stiff or swollen if people overuse them.


Psoriatic arthritis is caused by an overactive immune system, which causes inflammation in the joints, skin, and other body parts. Rheumatoid Arthritis is a condition that can cause pain, stiffness and swelling in multiple joints. This type is said to be more common among people with psoriasis.

  1. Spondylitis psoriatic arthritis

Spondylitis psoriatic arthritis is inflammatory arthritis that causes inflammation and pain in one or more joints. The main symptom is a pain in the joints, as well as inflammation, swelling, redness and stiffness. This condition can affect any joint but most commonly occurs in the spine, hip or knee. Joints may also be due to long-term spondylitis psoriatic arthritic problems. The pain usually starts as mild discomfort but, if left untreated, could become severe.


These can include the following:

  • Hips
  • Arms
  • Legs
  • Hands
  • Feet
  1. Psoriatic arthritis mutilans

Psoriatic arthritis mutilans is a type of psoriatic arthritis that causes inflammation and typically develops in both feet, hands, or wrists. However, it can also develop in other parts of the body. The joints may become deformed or stiff because they are not moving enough due to pain. Psoriatic arthritis mutilans is a debilitating form of psoriasis that affects many people’s quality of life.

  1. Psoriatic Arthritis Mutilans 
  2. Type One- Joints and Skin Affected 
  3. Type Two- Muscles and Other Body Systems Affected 
  4. Type Three- Nervous System Affected 
  5. Type Four- Eye Affected


This can lead to symptoms like:

  • Deformities of the manufactured joint, which can be severe
  • Problems with movement and range of motion
  • Bone loss in the manufacturing joint can guide to shortening of the fingers or toes
How is psoriatic arthritis diagnosed?

Psoriatic arthritis is a chronic, progressive autoimmune disease that causes joint inflammation, which may result in joint pain and stiffness. Psoriatic arthritis is a type of inflammatory arthritis that involves specific antibodies attacking skin cells called keratinocytes. It is diagnosed by taking a detailed medical history, examining your joints and skin, and carrying out blood tests to check for these antibodies. There are five different forms of psoriatic arthritis: plaque-type psoriasis (psoriasis), nail pitting (onycholysis), dactylitis or finger clubbing, erythroderma or redness all over the body, and psoriatic arthropathy.
