Plaque Psoriasis On Dark Skin

What Does Psoriasis Look Like On Black Skin

Psoriasis, Causes, Types, Sign and Symptoms, Diagnosis and Treatment.

Around 125 million people worldwide have psoriasis. A 2014 study involving more than 6,000 people found that the prevalence of psoriasis was about 1.9 percent in Black participants and 3.6 percent in white participants. But psoriasis rates among Black folks may be even higher IRL.

Psoriasis can be easy to spot on white skin. It shows up as pink or red lesions with silvery scales. But on Black skin, lesions tend to be purple or violet with gray scales. This might make the condition harder to diagnose.

PSA: According to the National Psoriasis Foundation, people with darker skin receive incorrect diagnoses or go undiagnosed with psoriasis more often than light-skinned people.

Anyone can have psoriasis. It isnt exclusive to one ethnic group or age group. But symptoms can vary based on your skin type and tone.

Heres how the most common forms of psoriasis appear on Black skin.

What Kind Of Doctor Treats Psoriasis

There are several types of doctors who may treat psoriasis. Dermatologists specialize in the diagnosis and treatment of skin disorders, including psoriasis. Rheumatologists specialize in the treatment of joint disorders, including psoriatic arthritis. Family physicians, internal medicine physicians, rheumatologists, dermatologists, and other medical doctors may all be involved in the care and treatment of patients with psoriasis.

Spectrum Of Treatment Options

Although psoriasis presents differently on various skin types, color doesnât necessarily determine treatment options. Patients should consult with their health care providers to personalize their treatment plans. Creams, ointments and topical steroids are typically the first line of defense against psoriasis, while more severe cases require more aggressive therapies.

âWhen people of color present with psoriasis, especially African-American patients, they often have more hyperkeratotic, or thicker-scaled lesions,â says McMichael. âThat means the lesions are going to take a longer time to control, with medication at higher potency levels.â

If creams donât help, phototherapy can be very effective for people with darker skin pigment, she says, noting the lack of research on treatment for skin of color, as most studies predominantly feature white patients. That situation is changing, however. In 2017, the Patient-Centered Outcomes Research Institute awarded an $8.6 million contract to one of Takeshitaâs colleagues, Joel Gelfand, M.D., a board-certified dermatologist whose clinical work focuses on general dermatology and psoriasis. The PCORI contract is for a clinical trial called LITE. The purpose of LITE is to study the effectiveness and safety of 12 weeks of home-based versus office-based phototherapy for the treatment of psoriasis, and the effects of phototherapy across skin tones.

How To Deal With Psoriasis On Black Skin

Here are some top-notch tips to keep your psoriasis symptoms under control:

  • Let it be. Picking or scratching at scales increases your risk of bleeding, oozing, or infection. If things get to The Itchy & Scratchy Show status, ask your doc which anti-itch creams are best for short-term or long-term use.
  • Let it go. Stress is a major psoriasis trigger. Relaxing activities can help you stay calm. Yoga, meditation, and walking are all chill choices. You could also try getting creative or journaling!
  • Lather up. Go with a daily moisturizer that can soothe scaly skin. Your doc can recommend a medicated cream if over-the-counter options dont cut it.
  • Be aware of your triggers. Avoid activities or food that make your skin go cray.
  • Switch products. Some body products contain harsh chemicals that can irritate sensitive skin. Opt for lotions, creams, and shampoos with no added fragrances, dyes, or parabens.

Treatments Are Equally Effective

Treatment for psoriasis is typically the same across the board for all races, however, there are certain factors, like hair type, that may affect a physicians suggested treatment plan for a patient with say, scalp psoriasis. Hair care practices in African American patients are very different than those in Caucasian patients, so this can influence how we treat scalp psoriasis, says Joshua Zeichner M.D., who serves as the director of Cosmetic & Clinical Research in Dermatology at Mount Sinai Hospital in New York City. Its important to tailor a prescription regimen to the personal needs and preferences of the patientfor instance, if someone is only washing their hair once per week or every other week, we canât necessarily use the same treatments as we would if they were washing daily, as over-washing can lead to increased dryness and damage to the hair itself.

As for skin tone, Dr. Sodha says there are no off-limit treatments. We follow the same algorithm of treatment using topical therapies for less severe disease, followed by light therapy and systemic treatments for patients needing a more aggressive approach. Dr. Finney agrees: Treatments in psoriasis are the same across all ethnic groupsthe only minor difference is that when light treatment is chosen, higher doses may be required in darker skin tones due to the increased amount of melanin present in the skin, he says.

How Psoriasis Is Diagnosed

A GP can often diagnose psoriasis based on the appearance of your skin.

In rare cases, a small sample of skin called a biopsy will be sent to the laboratory for examination under a microscope.

This determines the exact type of psoriasis and rules out other skin disorders, such as seborrhoeic dermatitis, lichen planus, lichen simplex and pityriasis rosea.

You may be referred to a specialist in diagnosing and treating skin conditions if your doctor is uncertain about your diagnosis, or if your condition is severe.

If your doctor suspects you have psoriatic arthritis, which is sometimes a complication of psoriasis, you may be referred to a doctor who specialises in arthritis .

You may have blood tests to rule out other conditions, such as rheumatoid arthritis, and X-rays of the affected joints may be taken.

Scarring Is More Prevalent In Dark Skin

As previously mentioned, psoriasis patients with darker skin tones are more susceptible to post-inflammatory hyperpigmentation or scarring than their Caucasian counterparts. This simply means that when a person with darker skin has a flare-up of psoriasis, it will leave behind discoloration on the skin even after the rash itself has healed. Unfortunately, the best way to avoid scarring is to avoid flare-ups altogether, though we know thats not always realistic. A few things you can do to prevent scarring include not scratching, moisturizing often, and protecting your skin from the sun, as we know sun damage is a surefire way to make scarring worse.

What Does Psoriasis Look Like

Psoriasis usually appears as red or pink plaques of raised, thick, scaly skin. However, it can also appear as small, flat bumps or large, thick plaques. It most commonly affects the skin on the elbows, knees, and scalp, though it can appear anywhere on the body. The following slides will review some of the different types of psoriasis.

It Often Goes Undiagnosed

Psoriasis is likely to be under- or misdiagnosed in African Americans and people with skin of color. For instance, according to Dr. Sodha, these patients are 52% less likely to report having been given a psoriasis diagnosis by a physician. There are a few reasons for this, like the fact that people of color are 40% less likely than whites to report having seen a dermatologist for care. They also report three million fewer overall out-patient visits for psoriasis, Dr. Sodha notes. And population studies of psoriasis patients show that African Americans tend to report lower income and fewer years of education, which likely affects access and utilization of healthcare, thereby delaying diagnosis, leading to disease progression and delayed initiation of treatment.

Expertsand patientsagree that this is where education and normalizing conversations about skin conditions within diverse communities will help. My hope is that dermatologists are exposed to a diverse range of skin tones when theyre trained and educated, as well as in residency,” says patient advocate Reena Ruparelia of . This will ensure that patients get the best care and the peace that comes with a formal diagnosis.

Quality Of Life And Disease Severity

Studies suggest the quality of life effect on people with darker skin is far worse than it is for people with fair skin. Potential reasons may include the long-lasting effect of psoriasis, especially in the development of pigment abnormalities. Cultural perceptions of the disease may also adversely affect the quality of life, as psoriasis tends to be a condition of stigma and misconception. This was confirmed by a study reported in 2011 by the Journal of Drugs in Dermatology noting that African Americans and Asians were more profoundly affected by psoriasisboth physically and emotionallythan people with fair skin.

Disease severity may also be a problem for people with darker skin. A study reported in 2017 in the Journal of the American Academy ofDermatology aimed to determine differences in severity based on ethnicity. The studys researchers examined a database of ethnically diverse psoriasis patients who were seen at the University of San Franciscos Department of Dermatology. What they found was that African Americans, Hispanics, and Asians had more severe psoriasis than the white study subjects.

What Causes Psoriasis Patches

Psoriasis patches are caused when the skin production process becomes accelerated and inflammatory cells move into the dermis . Traditionally, skin cells replace themselves approximately every 27 days, however, the skin cells in those with psoriasis often replace themselves within just a few days. This sped-up process does not allow for old skin cells to fall away from the skin thus causing skin cells to build on top of one another, creating patches of rough, scaly skin.

What are the different types of psoriasis?

The most common type of psoriasis is plaque psoriasis, which accounts for over 80% of cases. Plaque psoriasis appears as red to purplish plaques or patches on the skin with silvery-white or gray scales. These patches commonly appear on the elbows, knees, scalp, belly button, and upper buttocks but may appear almost anywhere!.

Other types of psoriasis include:

Your dermatologist can help you identify which type of psoriasis you may be experiencing.

When It Comes To Treating Psoriasis Skin Color Matters

When it comes to treating psoriasis in non-white patients, there is a paucity of data on differences in epidemiology, clinical presentation, and approaches to treatment.

“Although psoriasis appears to have a lower prevalence in non-white racial ethnic groups, including African Americans, it is by no means an uncommon or rare disease,” said Andrew Alexis, MD, chair of the department of dermatology and director of the Skin of Color Center at Mount Sinai St. Luke’s and Mount Sinai West in New York City, speaking about the topic at the Skin of Color Seminar Series in New York City.

In fact, a recent study found a 1.9% prevalence rate of psoriasis in African Americans. “This is much more common than previously reported,” Alexis said.

The clinical presentation of psoriasis in darker-skinned individuals can vary, based primarily on the visual appearance. For example, because of the background melanin pigmentation, “the erythema may look more violaceous, hyperpigmented, or dark brown or gray. Therefore, one has to train the eye to detect psoriasis-related erythema in darker skin types,” he explained.

Diagnostic Pearls

Clues of psoriasis include the quality of the scale, the anatomic distribution, and associated features.

There are scenarios, though, where a biopsy is needed to confirm the diagnosis of psoriasis. “I find this is more frequent in darker skin types,” Alexis said.

What Are The Signs And Symptoms Of Psoriasis

Dry, thick, and raised patches on the skin are the most common sign of psoriasis. These patches are often covered with a silvery-white coating called scale, and they tend to itch.

While patches of thickened, dry skin are common, psoriasis can cause many signs and symptoms. What you see and feel tends to vary with the:

  • Type of psoriasis you have

  • Places psoriasis appears on your body

  • Amount of psoriasis you have

Identifying and treating psoriasis in skin of color present a unique set of challenges for practitioners, leading to a call for advanced education.

Disparities have been shown in how the disease is identified due to its presentation in non-white skin types, while treatment disparities and mental health impacts in individuals with skin of color have also been identified.

Diagnosing psoriasis often leads with identifying erythema. The red, scaly patches common to the condition are generally easy to spot on lighter skin, but in skin of color, erythema presents much differently.

There are many features of psoriasis that present similarly across skin types. For example, the symmetrical distribution of psoriasis on the body and well-circumscribed nature of psoriasis plaques. An important difference that clinicians need to keep in mind is that the pink-to-red color that is typically seen with psoriasis on light skin often appears more purple or brown in darker skin types, assistant professor of dermatology and epidemiology at the Perelman School of Medicine at the University of Pennsylvania, said. Sometimes the scale that accompanies psoriasis is so thick that it is difficult to appreciate that underlying color of the plaque itself.

Symptoms Are The Same But Can Look Different

Symptoms of psoriasis do not vary by skin tone, says Dr. Finney. And yet, despite having the same symptoms psoriasis can look somewhat different on deeper skin tones. On dark skin, the plaques may appear purple or grayish and thicker compared to the pink-red scaly plaques that appear on Caucasian skin, explains Dr. Finney. And once healed, psoriasis may leave behind dark or light skin patches, which are more apparent in people of color.

Additionally, Dr. Sodha says that redness is typically less apparent in those with darker skin, though youll still see thickened, scaly patches of skin just like anyone else with plaque psoriasis. Patients with darker skin types are frequently troubled by light and dark discoloration of the skin after treatment that can take months to resolve or, in some cases, be permanent, adds Dr. Finney.
