Are you wondering, "What is psoriasis?" Psoriasis is a chronic autoimmune disorder that primarily affects the skin, causing rapid skin cell turnover. This results in thick, scaly patches appearing anywhere on the body. This blog aims to help you understand the causes, symptoms, and potential treatments for this uncomfortable inflammatory skin condition. Whether you're concerned about your symptoms or exploring ways to manage them, this guide will provide insights into this condition and how it compares to other skin conditions like eczema and seborrheic dermatitis. Below, the dermatology experts at the Dermatology & Cutaneous Surgery Institute (DCSI) explain more about psoriasis and its similarities to other skin conditions.

Is Psoriasis a Fungal Infection?

Many don't realize that psoriasis is not a fungal infection but rather a chronic autoimmune disorder. This condition causes the immune system to mistakenly attack healthy skin cells, leading to rapid skin cell turnover. In contrast, fungal infections are caused by fungi like yeast or mold. Although some symptoms like redness and scaling can resemble fungal infections, they require different treatments. Antifungal creams, for example, will not help psoriasis and may even worsen symptoms in some cases.

Is Psoriasis a Chronic Inflammatory Disease?

Because it involves systemic inflammation, not just affecting the skin but potentially increasing the risk of other conditions like heart disease or arthritis (psoriatic arthritis), this condition is considered a chronic inflammatory disease. The inflammation results from an overactive immune response, causing the skin to produce cells too quickly, leading to the characteristic plaques and redness.

Can Psoriasis and Lupus Be Confused for Each Other?

Lupus and psoriasis can sometimes be confused because both conditions are autoimmune diseases that affect the skin and can cause similar symptoms like rashes, redness, and inflammation. However, the nature of the rash is different. Lupus often causes a butterfly-shaped rash across the face, whereas psoriasis tends to form thick, scaly plaques on different parts of the body. A dermatologist or rheumatologist can distinguish between the two based on a thorough clinical examination and diagnostic tests, such as blood work or skin biopsies.

Could Someone With Psoriasis and Gastrointestinal Issues Be Misdiagnosed?

While psoriasis can coexist with psoriatic arthritis, Crohn's disease, and other autoimmune conditions, it is possible for these symptoms to be confused with other diseases like lupus or scleroderma. Both lupus and scleroderma can cause joint pain, skin changes, and gastrointestinal issues, which overlap with psoriatic arthritis and Crohn's disease. If someone is experiencing a combination of these symptoms, further diagnostic tests may be necessary to rule out other autoimmune conditions. Blood tests, imaging studies, and biopsies can help clarify the diagnosis and guide appropriate treatment.

Psoriasis vs. Eczema vs. The World - Different Conditions

Are you wondering what the difference is between psoriasis and eczema? Both are chronic skin conditions but have different underlying causes and symptoms. Psoriasis is an autoimmune condition that causes thick, scaly patches, often with silvery scales, while eczema is an inflammatory condition that results in itchy, red, and dry skin. Eczema typically affects the insides of elbows and knees, while psoriasis often appears on the scalp, elbows, and knees and it tends to be more persistent and less itchy than eczema.

Can You Have Both Psoriasis and Eczema?

Though relatively rare, it is possible to have both psoriasis and eczema. Each condition is managed differently, so it's crucial to consult a dermatologist for a proper diagnosis and treatment plan. Psoriasis treatments may not be effective for eczema and vice versa, so a combination approach may be necessary.

How Do I Know If I Have Eczema or Psoriasis?

Distinguishing between eczema and psoriasis can be challenging because they share symptoms like red, inflamed skin. However, the latter typically has thicker plaques with a silvery-white appearance, while eczema is more likely to cause oozing, itchy rashes. A dermatologist can accurately diagnose the condition based on the appearance of the lesions and may perform a skin biopsy if needed.

What's the Difference Between Psoriasis and Dandruff?

Dandruff and psoriasis both affect the scalp, but they are different conditions. Dandruff causes flaky, itchy skin but doesn't involve the thick, scaly plaques. Scalp psoriasis may extend beyond the hairline and be more inflamed and persistent than dandruff. Treatments for this condition are often more intensive than those for dandruff, which can usually be managed with over-the-counter shampoos.

What Is the Difference Between Psoriasis and Seborrheic Dermatitis?

Seborrheic dermatitis and psoriasis can both cause scaly patches, particularly on the scalp, but they are distinct conditions. Seborrheic dermatitis generally produces yellowish, greasy scales, especially around the nose, eyebrows, and scalp. It is also often easier to manage with medicated shampoos and creams. Psoriasis plaques are thicker and drier and can extend beyond the scalp to other body parts, and they may require more specialized treatments like phototherapy.

What Is Gastric Psoriasis?

Gastric psoriasis is not a recognized medical term, and the skin rash it causes does not typically affect the gastrointestinal system. However, some people with this inflammatory skin condition may develop other inflammatory conditions, including psoriatic arthritis and Crohn's disease, which affect the digestive system. If you have digestive issues and psoriasis, consult your healthcare provider to explore possible connections.

Who Can Get Psoriasis?

Anyone can be affected by this skin condition, regardless of gender, ethnicity, or age, although certain factors increase the likelihood of developing the condition. It is an autoimmune disease, and while the exact cause is not fully understood, both genetic and environmental factors play a role.

What Section of the Population Is Most Likely to Have This Condition?

Psoriasis is more common in people with a family history of the condition. Individuals of Northern European descent have a higher incidence, while it is less common in African, Asian, and Native American populations. Environmental triggers like stress, infection, or injury to the skin can also contribute to its onset.

At What Age Is This Condition Most Frequently Diagnosed?

Though diagnosable at any age, it is most commonly diagnosed between 15 and 35. There is also a second peak in diagnosis later in life, typically between 50 and 60.

Does a Person's Skin Color, Ethnicity, Age, or Other Demographics Contribute to the Likelihood of a Person Having Psoriasis?

As with other genetically inherited conditions, demographics like age, ethnicity, and family history influence the likelihood of developing psoriasis. As mentioned earlier, people of Northern European descent are more likely to develop the condition which tends to appear earlier in life for some individuals. It can affect all skin colors, though it may be more challenging to detect on darker skin tones. Psoriasis does not discriminate based on gender, but individuals with a family history of autoimmune diseases are at higher risk.

Can Babies Have Psoriasis?

While psoriasis is less common in babies, it can occur. It often presents as a diaper rash or red, scaly patches on the scalp and face. However, because infant skin conditions can be challenging to diagnose, it's important to consult a dermatologist if you suspect this in a baby. Early diagnosis and treatment can help manage symptoms and avoid unnecessary discomfort.
