Psoriasis And Cancer: Whats The Link
- By Dominic Wu, MD, Contributing Editor
Psoriasis is a relatively common, chronic inflammatory skin condition. It is likely caused by genetic predisposition combined with triggers such as infections, trauma, stress, and medications. The classic presentation is itchy, scaly, pink plaques most commonly found on the elbows, knees, and scalp.
In a recent systematic review and meta-analysis of 58 studies published in JAMA Dermatology, researchers found an association between psoriasis and an increased risk of developing cancer.
The JAMA Dermatology study focused on data from previous studies analyzed between April 9, 2018, and February 22, 2019. The researchers found that people with psoriasis had an increased risk of developing cancers including colon, kidney, laryngeal, liver, lymphoma, non-Hodgkin lymphoma, esophageal, oral, and pancreatic cancers. They also found that people with severe psoriasis who developed cancer also had an increased overall risk of dying.
Can Psoriasis Affect Only My Nails
In some cases, psoriasis may involve only the fingernails and toenails, although more commonly, nail symptoms will accompany psoriasis and arthritis symptoms. The appearance of the nails may be altered, and affected nails may have small pinpoint pits or large yellow-colored separations on the nail plate called “oil spots.” Nail psoriasis can be hard to treat but may respond to medications taken for psoriasis or psoriatic arthritis. Treatments include topical steroids applied to the cuticle, steroid injections at the cuticle, or oral medications.

Itchy Skin With No Rash Is It Cancer
While itchy skin is commonly associated with rashes, not all rashes are itchy, and not all itchiness is accompanied by a rash. Experiencing itchy skin without visible redness could be a sign of skin cancer.;
Medically known as pruritus, itchy skin without a rash is sometimes a sign of a more serious condition such as skin or liver cancer. To be safe, talk to a health care provider if you experience persistent and unexplained itching.

Symptoms Of Bowen’s Disease
Bowen’s disease usually appears as a patch on the skin that has clear edges and does not heal.
Some people have more than 1 patch.
- up to a few centimetres across
- itchy
The patch can appear anywhere on the skin, but is especially common on exposed areas;like the lower legs, neck and head.
Sometimes they can affect the groin area and, in men, the penis.
If the patch bleeds, starts to turn into an open sore or develops a lump, it could be a sign it’s turned into squamous cell skin cancer.
How Skin Conditions Can Affect Skin Cancer Detection And Treatment
Millions of Americans are affected by skin cancer, but millions more are battling skin conditions like rosacea, eczema, psoriasis and melasma. Although bothersome, these conditions are usually harmless and manageable through ongoing treatment.
In dealing with my own bout of melasma, I got to thinking can these skin problems make it harder to spot a potential skin cancer? Can a dermatologist treat a patients condition and skin cancer simultaneously? I asked James Sandwich, MD, MPH a board-certified dermatologist practicing in Fayetteville, Georgia, to break down these conditions for us and how they impact skin cancer diagnosis and treatment.

Is Bowen’s Disease Serious
Bowen’s disease itself is not usually serious. It tends to grow very slowly over months or years, and there are several very effective treatments for it.
The concern is that Bowen’s disease can eventually develop into a different;type of skin cancer called;squamous cell skin cancer;if it’s left undiagnosed or neglected.
It’s estimated this happens in up to 1 in 20 to 1 in 30 people with untreated Bowen’s disease.
Squamous cell skin cancer is often treatable, but;it can;spread deeper into the body and is sometimes;very serious.
Actinic Keratosis On An Arm
This photo contains content that some people may find graphic or disturbing.
Actinic keratosis, also called solar keratosis, is a precancerous skin lesion usually caused by too much sun exposure. It can also be caused by other factors such as radiation or arsenic exposure.
If left untreated, actinic keratoses can develop into a more invasive and potentially disfiguring skin cancer called squamous cell carcinoma. They appear predominantly on sun-exposed;areas of the skin such as the face, neck, back of the hands and forearms, upper chest, and upper back. You can also develop keratoses along the rim of your ear.
Actinic keratosis;is caused by cumulative skin damage from repeated exposure to;ultraviolet light, including that found in sunshine. Over the years, the genetic material in your cells may become irreparably damaged and produce these pre-cancerous lesions. The lesions, like those seen here on the arm, can later become squamous cell carcinoma, a more invasive cancer.

What Happens If Squamous Cell Carcinoma Is Left Untreated
Untreated squamous cell carcinoma of the skin can destroy nearby healthy tissue, spread to the lymph nodes or other organs, and may be fatal, although this is uncommon. The risk of aggressive squamous cell carcinoma of the skin may be increased in cases where the cancer: Is particularly large or deep.
Signs And Symptoms Of Psoriasis
Psoriasis is a chronic skin condition that develops as the result of an overactive immune system. Normally, T-cells in the immune system function by attacking bacteria and viruses that lead to infection and harm the body. If you have psoriasis, T-cells mistakenly begin attacking healthy skin cells. This causes the life cycle of skin cell production to speed up and generate a surplus of new skin cells in a matter of days. The new cells build up on the surface of skin and form thick patches and scales that can be itchy, painful, or burning.
The most common symptom is the appearance of well-defined, raised red patches of skin covered with silvery scales. These thick skin lesions typically appear on knees, elbows, scalp, trunk, buttocks, and nails. However, the disorder can affect any area of skin on the body, including the genital region.
Under the broad name psoriasis, there are many different types:
- Plaque psoriasis is the most well-known form the skin condition takes. It is characterized by thick, raised red plaques that develop on the scalp, elbows, knees, and/or trunk. The plaques are often covered by dry, itchy silver-white scales.
- Nail psoriasis causes changes to the nails. Both fingernails and toenails can develop pitting, discolorations, and crumbling. Due to the build-up of skin cells under the nail, one or more nails can lift and become detached.

Tips For Getting The Right Diagnosis
For the best chance of getting the right diagnosis, a person should make sure they give an accurate history when a doctor or dermatologist asks. The more information a medical professional has to work with, the more likely they are to diagnose a persons illness correctly.
This is especially important with skin conditions such as psoriasis. A medical professional will typically rely on both a history and a visual assessment to work out what a persons skin condition is. A visual assessment alone may not be enough.
If a person is unsure about their diagnosis, they can request further diagnostic tests. This may involve speaking to a dermatologist, who might use dermoscopy or recommend a skin biopsy.
A skin biopsy involves taking a small sample of the skin and sending it to a lab for testing.

Recognizing Neoplastic Skin Lesions: A Photo Guide
LEWIS C. ROSE, M.B., B.S., University of Texas Health Science Center, San Antonio, Texas
Am Fam Physician.;1998;Sep;15;58:873-884.
;Patient information: See related handout on skin cancer, written by the author of this article.
Malignant lesions of the skin are common. Patients who develop squamous cell carcinoma and malignant melanoma often have recognizable precursor conditions. A few skin lesions resemble malignancies. Lesions that are growing, spreading or pigmented, or those that occur on exposed areas of skin are of particular concern. Knowing the similarities and differences between these lesions allows the primary physician to make a diagnosis in most cases by simple inspection and palpation. When in doubt, it is appropriate to perform an excisional biopsy of small lesions or punch biopsy of larger lesions. Removal of premalignant lesions will reduce the occurrence of malignant disease. Almost all skin cancers can be cured by early excision or destruction. For these reasons, physicians should be aware of the risk factors for skin cancer, educate patients about risk reduction and include skin inspection for premalignant and malignant lesions as a part of routine health maintenance examinations.

There are a number of treatment options for Bowen’s disease.;Talk to your dermatologist about which treatment is most suitable for you.
The main treatments are:
- cryotherapy liquid nitrogen is sprayed on to the affected skin to freeze it. The procedure may be painful and the skin may remain a bit uncomfortable for a few days. The affected skin;will scab over and;fall off within a few weeks.
- imiquimod cream or chemotherapy cream this is applied to the affected skin;regularly;for a few weeks. It may cause your skin to become red and inflamed before it gets better.
- curettage and cautery the affected area of skin is scraped away under;local anaesthetic, where the skin is;numbed, and heat or electricity is used to stop any bleeding, leaving the area to scab over and heal after a few weeks.
- ;;a light-sensitive cream is applied to the affected skin and;a laser is directed on to the skin a few hours later to destroy the abnormal cells. The treatment session lasts about 20 to 45 minutes. You may need more than 1 session.
- surgery the;abnormal skin is cut out under local anaesthetic and stitches may be needed afterwards.
