What Causes Psoriasis On Fingers

How Is Nail Psoriasis Diagnosed

Most effective treatment for Psoriasis – Dr. Rajdeep Mysore

Your healthcare provider can typically diagnose nail psoriasis after a physical exam. Theyll examine your affected areas to look for common signs of nail psoriasis. Theyll also ask about your symptoms and your family history.

Once your healthcare provider has diagnosed nail psoriasis, they may use the nail psoriasis severity index to grade its severity. The NAPSI uses imaginary lines to divide your nail into four even sections . Your nails receive a 0-4 score based on the presence of any nail psoriasis symptoms in each of the quadrants. Your healthcare provider will then add the scores together. A low number means your nail psoriasis is mild, and a high number means your nail psoriasis is more severe.

People with nail psoriasis may develop a number of symptoms. Providers use NAPSI to determine the severity of the condition.

If theres any doubt about your symptoms, your healthcare provider may order a potassium hydroxide preparation or fungal culture to rule out a fungus as the cause of your symptoms. If those test results arent clear, a fungus test known as a periodic acid-Schiff stain can also determine the presence of a fungus.

Symptoms Of Nail Psoriasis

Symptoms of nail psoriasis can vary from one person to the next and alter as the disease progresses.

  • Redness in the white arch at the base of the nail
  • Arthritis in the finger or toe with nail damage

While nail psoriasis symptoms may appear on both the nails of the toes and fingers, the latter is more common. It usually affects a few digits, rather than just one.

What Causes Scalp Psoriasis

Regardless of where psoriasis forms, the cause is the same. Psoriasis develops when a persons immune system has faulty signals that tell skin cells to grow too quickly. New skin cells form in days rather than weeks. The body does not shed these excess skin cells. The skin cells pile up on the surface of the skin, causing patches of psoriasis to appear.

Psoriasis Can Affect Both Fingernails And Toenails

Psoriasis can affect both fingernails and toenails, with half of those with psoriasis alone having some form of nail involvement. The risk increases in those with psoriatic arthritis, and it is reported that this could be as high as 4 out of 5 people seeing changes to their nails. For some unknown reason fingernails are more often involved than toenails. For many people, nail psoriasis is often mild and causes few problems.

The nails are part of the skin, so it is perhaps not surprising that a skin disease such as psoriasis can affect the nails. No one knows why some people get nail involvement and others dont. Nails grow from the nail root , which is just under the cuticle. In people who develop nail psoriasis it is involvement of the nail root that causes pitting and ridging of the nails.

Onycholysis , subungual hyperkeratosis and splinter haemorrhages are all caused by disease of the nail bed. These conditions are explained in the next section.

The nail is made of modified skin and, once it has grown, it can only be altered by filing or clipping. Treatments are usually directed at the nail bed that supports the nail or the nail folds that tuck around the edges. Soothing these tissues can result in better nail growth with fewer features of psoriasis.

How Can Ppp Be Treated

Topical Treatment

Treatment is likely to begin with topical treatments, including steroid creams and coal tar applications. A healthcare professional may advise steroid-based treatments to be applied under occlusion , as it can help the treatment it to be absorbed through thickened skin. This must only be done on advice from a healthcare professional, and is not appropriate for all types of psoriasis or all body areas.

Other topical treatments such as coal tar or salicylic acid may also be used, to help reduce thick scaling.

As with all types of psoriasis, it is important to moisturise well and regularly, as this will help the skin to feel more comfortable, and can help active topical treatments to be better absorbed. In the case of PPP, moisturising can also help to prevent or reduce cracking of the skin.


PPP can be stubborn to treat, and, should this be the case, a Dermatologist may prescribe a course of Psoralen Ultraviolet A therapy. PUVA therapy for the hands and feet involves taking oral psoralen or applying topical psoralen to the affected areas before exposure to the ultra-violet A radiation. This is especially useful for the feet as the patient sits with the soles exposed to a small UVA machine, as opposed to standing in a cabinet, where the soles are not reached by light.

Systemic and Biologic Treatments

How Does Psoriasis Affect The Palms And Soles

Psoriasis may be localised to the palms and soles or part of generalisedchronic plaque psoriasis. Two common patterns are observed:

  • Well-circumscribed, red, scaly, plaques similar to psoriasis elsewhere
  • Patchy or generalised thickening and scaling of the entire surface of palms and/or soles without redness
Palmoplantar psoriasis

Palmoplantar pustulosis and the rare acrodermatitis continua of Hallopeau , in which yellow-brown pustules occur, are no longer classified as psoriasis. However, the conditions are associated. About 1025% of people with palmoplantar pustulosis also have chronic plaque psoriasis.

Some people — mostly adults who smoke — get pustular psoriasis on their palms and soles. Known as palmoplantar pustulosis , it can erupt over months or years.

What Are Hand Psoriasis Treatments

Dyshidrosis, Causes, Signs and Symptoms, Diagnosis and Treatment.

You probably already know that psoriasis on the hands can be challenging to treat. While that can feel a little disheartening, know that there are still lots of options to try.

There are some treatments, such as certain topical creams or ointments, that can help with both psoriasis and eczema, Dr. Rosmarin says. The immune system is too active in the skin, so we have medicines that can tell the immune system to calm down.

Typically, the first-line treatment for psoriasis plaques on the hands is topical corticosteroids, which come in the form of anti-inflammatory creams, ointments, or gels. Sometimes, a doctor may recommend applying this with occlusionthis means wearing gloves or wrapping the hands, ideally to allow the medication to better penetrate. Other times, your dermatologist will recommend combining this medication with calcipotriene, an ointment that helps to slow skin cell growth.

Another topical application is acitretin. Its a form of vitamin A that can take three to six months of steady application to see results.

Unfortunately, psoriasis plaques can sometimes be so thick that its difficult for the topical medications to fully penetrate the skin. When this is the case, you may need to turn to the second-line treatments. These usually involve systemic treatments or light therapy.

Medications That Stop Disease Progress

Psoriasis is an immune system condition, so if skin treatments donââ¬â¢t work, your doctor may recommend drugs that affect the disease at a cellular level. These include:

  • Cyclosporine, to slow down your overactive immune system
  • Low-dose retinoids like acitretin , to reduce cell multiplication
  • Methotrexate, which slows an enzyme that causes the rapid growth of skin cells in psoriasis

Doctors often combine retinoids with light therapy for hands and feet psoriasis. You might have UVB or psoralen-UVA phototherapy or targeted phototherapy . PUVA involves taking the drug psoralen, either by mouth or applied like paint, along with the light therapy.

If these treatments donââ¬â¢t work, your doctor may prescribe a type of medication called a biologic, which targets specific parts of the immune system. Different types of psoriasis respond in different ways to these medications. Examples include:

Clinical Trials For Psoriasis

Before a new treatment can be registered in Australia it must undergo extensive testing. Clinical trials are used to determine the safety and effectiveness of new treatments for psoriasis. The regulations governing clinical trials in Australia make the process as safe as possible for clinical trial participants. People with psoriasis may consider volunteering to participate in a clinical trial. Participation provides volunteers with access to cutting edge treatments that are not otherwise available. General information about being part of a clinical trial can be found here. Internationally, provides patients, their family members, and the public with easy and free access to information on clinical studies for a wide range of diseases and conditions. If you are interested in participating in a clinical trial, talk to your doctor.

Long, hot baths and showers can dry out your hands and make your symptoms worse. Try to take no more than one a day, and keep it short — 5 minutes in the shower and 15 in the bath. Use warm — but not hot — water and a soap for sensitive skin. Skip loofahs and washcloths since they can be hard on your hands. Once you’re done, gently pat your skin with a towel and put on cream while your hands are still damp.

Psoriatic arthritis and psoriasis are both autoimmune conditions, caused by a fault in the immune system.

Our immune system protects us from illness and infection. But in autoimmune conditions, the immune system becomes confused and attacks healthy parts of the body, often causing inflammation.

Psoriatic arthritis is a type of spondylarthritis. This is a group of conditions with some similar symptoms.
