Psoriasis is a chronic, non-contagious skin condition that affects about two percent of the population. While the cause is unknown, psoriasis is linked in some way to the immune system. Skin cells reproduce markedly fast with buildups resulting in scaly red patches. These can be seen typically in the knees, elbows, groin and scalp. Read more about psoriasis in our patient education guide.
Mild cases of psoriasis start with dry, small patches on the skin. In more severe cases, reddened thick scaly patches may cover the whole body.
Although psoriasis is a non-curable condition, sufferers may experience long remission periods, especially in warmer climates where they have more exposure to sunlight.
There are four main types of psoriasis that a patient can be diagnosed with.
The Team
Physicians who have been involved with the ongoing care of an individual may initially diagnose psoriasis in a patient. Once the diagnosis is confirmed, however, the patient is usually referred to a specialist. Common specialists that a psoriasis patient encounters are listed in this patient education guide and include:
Dermatologists - This doctor is often the patient's regular doctor and may be the first physician to recommend further tests or procedures to be done by a specialist.
Rheumatologists - A surgeon skilled in operating on the breast. Breast surgeons often perform biopsies on a tumor found in the breast. They will also remove the tumor or breast if necessary. Some breast surgeons also do reconstructive surgery.
These physicians are accustomed to diagnosing and treating skin diseases and are therefore the most knowledgeable on up-to-date therapies available.
Alternative care practitioners include:
Acupuncturists - Treat patients by inserting and maneuvering needles into body areas to relieve pain and improve health.
Naturopaths - Educate patients in the use of lifestyle changes, diet, exercise and natural therapies to treat or prevent disease.
Homeopaths - Treat patients based upon the principle that the body can heal itself. Various solutions are administered toward returning health.
Chiropractors - Treat patients from the principle that medical conditions may be treated by putting the musculoskeletal system back into proper alignment.
How to Prepare
Having made your appointment with a healthcare provider, there are certain actions listed in this patient education guide that you need to take in order to maximize the benefit of your psoriasis doctor visit.
- On the day of the exam, shower and wash hair so that skin has no additional contaminants. This cuts down on infection if biopsy takes place.
- Clean nails prior to examination so abnormalities are better visualized
- Bring list of symptoms with a list of when and where they first appeared
- Bring a list of your medications and the dosage you are currently taking. Include supplements.
- Bring list of allergies and past medical history
- Have a list of questions that you would like to discuss with your physician
Questions to Ask Your Doctor About Osteoarthritis
From your initial psoriasis diagnosis throughout your treatment and care, you will have questions about your psoriasis. Ourt patient education gude lists questions to discuss with your doctor so you can make informed decisions about your condition.
Question About My Diagnosis
- What kind of psoriasis do I have? How severe is my psoriasis? Will it get worse?
- Will my symptoms ever go away?
- How can I achieve remission? Will my symptoms return if I am cleared?

- Are there support groups in this area?
Questions About My Treatment
- How can I get rid of my itching?
- What treatments do you recommend for me and why?
- What are the risks and adverse reactions of the treatment?

- If my psoriasis comes back after clearing up, will the treatment be the same?
- Do I have to stay on the treatment forever or is it for a certain time frame?
Questions About My Lifestyle & Family

- Would protective clothing make a difference for my condition?
- Is there a daily skin care routine that I should follow?

Common Tests or Labs to Diagnose Osteoarthritis - Patient Education
When looking for a diagnosis of psoriasis, your physician will do a complete examination of the skin, nails and scalp.
A biopsy (taking a small skin sample) may be taken to rule out conditions that look similar in appearance. In particular, your doctor will look to exclude:
- Ringworm (tinea corporis)- fungal red scaly circle rash
- Lichen planus-dry itchy bumps on arms or legs, inflammatory
- Pityriasis rosea- starts with one large spot on torso (herald patch) which branches out but confined to 6-8 weeks
- Seborrheic dermatitis- itchy, scaly, greasy, reddened areas of skin
- Dandruff - flaky white cells of the scalp
While there are no blood tests or radiological tests used to diagnose psoriasis, blood will be drawn for screening and monitoring the liver, kidneys and blood while on various oral medications for psoriasis.
Your doctor may screen your blood for the following:
- HIV
- Hepatitis B and C
- Tuberculosis
As you take oral medications to treat psoriasis, your doctor will monitor your blood for the following:
- Triglycerides
- Cholesterol and lipid panel
- Complete blood count
- Liver and Kidney enzymes
Common Treatments
Topical treatment is available for symptomatic relief and oral medications are available, as well, to address the problems associated with psoriasis. Read more in this patient education guide.

Phototherapy (Light Therapy)
Routine daily exposure to sunshine in short increments may be helpful to mild psoriasis. In addition, there are three types of light therapy:
- Psoralen and Ultraviolet A Therapy (PUVA) - Uses timed artificial-light in conjunction with a photosensitizing drug (psoralen) in pill or lotion form. Done 2-3 times/week in a medical office.
- Ultraviolet B Therapy (UVB) - Specific wavelength of artificial light treatment given 2-3 times/week. Exposure time is increased slowly by 15-60 seconds per week
- Narrow Band Ultraviolet B Therapy - Similar to UVB treatment, but uses a different frequency. Occasionally Narrow band UVB treatments are combined with tar treatments (Goeckerman therapy).

If topical treatments and light therapies are unsuccessful, your physician may add medications to your regime.
