What Causes Psoriasis on Hands and Feet?

Psoriasis on Hands and Feet Why and How to Prevent It?

Like any other kind of psoriasis, psoriasis on hands and feet is caused by unknown reasons.

However, researches show that autoimmune mechanisms and genetics are their major causes.

  • Autoimmune Mechanism

Due to some unidentified reason, your immune system may start attacking your normal skin cells.

This attack of the immune system is called an autoimmune mechanism.

Due to this mechanism, skin cells start proliferating at a faster rate.

As shedding of the older skin cells occurs at the normal rate, newly formed skin cells start accumulating on the skin surface. It further leads to plaque formation, which is linked to psoriasis.

Due to this immune assault, skin also becomes reddish around plaques. Scales may also develop.

  • Genetic Cause

Psoriasis on hands and feet can also happen due to a genetic basis. Some people acquire disease-causing genes from their parents.

Such people have a higher chance of developing this skin condition at any time in life.

Some studies also reveal that certain mutations occurring in the normal genes can disrupt their function and cause psoriasis.

However, more research needs to be done to study these genes or mutations and understand their real connection with psoriasis.

Let’s find what the common types of psoriasis on hands and feet are.

Types of Psoriasis on the Hands and Feet

Psoriasis on the hands and feet has several variations; just like psoriasis on other body parts, it can be identified in 5 different visual types.

Only with a medical checkup you can confirm exactly what type you have and what treatment options are available.

Pustular Psoriasis on Hands and Feet

It is a rare form of psoriasis that mostly occurs in adults (very uncommon in children).

As the name indicates, small pustules form in this illness. It progresses speedily and more commonly affects hands and feet (palms, soles, fingers, and toes).

Your skin will first become red and sensitive. In a few hours, small white pustules filled with pus start forming on the skin.

These small blisters will join each other and become larger in the next few hours. After some hours, they will get dried, making skin flaky and scaly.

With proper treatment, its symptoms can be reduced, or your skin can get recovered, but any environmental trigger can make them reappear at any time.

Pustular psoriasis usually occurs in people who have plaque psoriasis. It can be transferred from one generation to the other.


  • A person suffering from pustular psoriasis may develop the following symptoms.
  • Formation of small pustules (they become larger with time)
  • Itching on pustules
  • Inflammation on skin

Palmoplantar Psoriasis (PPP) on Hands and Feet

Palmoplantar psoriasis is another type of hand and feet psoriasis. Of all the people having psoriasis, only 3% to 4% get this type of disease.

It usually occurs in people of age ranging from 20 to 60 years.

As it is a subcategory of pustular psoriasis similar pus-filled bristles form in it, too.

They become brown after some hours and get completely dried.

After that they may peel off from the skin, making the skin feel scaly and itchy.

Symptoms of palmoplantar psoriasis do not stay forever.

They vanish after appearing for a few days and reappear if the person is exposed to an environmental trigger.


Its symptoms are similar to the symptoms of pustular psoriasis. But the bristles appear majorly on the palms and soles. In rare cases, they develop on other body parts, as well.

Nail Psoriasis on Hand and Feet

Diagnosing psoriasis on limbs is a challenging task.

Doctors often confuse it with other diseases that have the same symptoms such as hand, foot, and mouth disease.
