Do You Think You Have Been Misdiagnosed?

Psoriasis Misdiagnosis

Psoriasis misdiagnosis

When you have an ongoing condition, like psoriasis, getting an accurate diagnosis is a vital. After all, psoriasis is a lifelong condition that can be managed with the right treatment plan.

But because psoriasis has symptoms and characteristics that mimic other conditions, it is possible your doctor may not diagnose you correctly.

Here is what you need to know about psoriasis, its symptoms, and what to do if you think you have been misdiagnosed.

What is Psoriasis?

Psoriasis is an inflammatory skin disease caused by the body’s malfunctioning immune system. The National Psoriasis Foundation reports at least 7.5 million Americans are affected.

It is not contagious condition despite misconceptions.

And it isn’t simply a skin disease because it starts underneath the skin. It is a chronic (long lasting) condition where symptoms range from mild to severe.

Symptoms of Psoriasis

Psoriasis is characterized by dry, flaky, red patches on the skin. These can appear anywhere on the body, but usually on the arms, legs, elbows, knees, and scalp.

The patches are a result of the body’s immune system triggering skin to reproduce too quickly resulting in cell buildup on the skin’s surface.

And psoriasis doesn’t just affect the skin. It may also affect the joints, causing stiffness and pain and tendons causing inflammation.

Psoriasis also increases your risk for heart disease, diabetes, psoriatic arthritis (a condition where you have both psoriasis and arthritis), and metabolic syndrome (a cardiovascular complication resulting in several other conditions).

Importance of Getting a Correct Diagnosis

Since psoriasis is known to affect your entire body, your doctor will likely take a wide-ranging approach.


But a big concern for psoriasis patients is many people, including doctors, consider psoriasis a skin condition and only look at the skin symptoms in diagnosis and treatment. And that is a big mistake leading to some serious health problems.

One study in the Dermatology Times finds severe psoriasis may lead to increased risk for cardiovascular and metabolic disorders.

Psoriasis can also lead to psoriatic arthritis (PsA) which leads to joint inflammation, depression, decreased life quality, and a shorter life span if not managed and treated properly. At least one-third of people with psoriasis will also develop PsA.

Educating Yourself About Psoriasis

To distinguish psoriasis from other skin conditions it helps if you understand the types of psoriasis and some of the other conditions psoriasis is often mistaken for.

Plaque Psoriasis

Plaque psoriasis is the most common type, affecting at least 80 to 90 percent of people with psoriasis according to the American Academy of Dermatology.

Plaque Psoriasis causes red, inflamed skin patches covered with silver, white scales that may itch and burn. These patches may appear anywhere on the body but they are mostly seen on the elbows, knees, low back, and scalp.


Guttate psoriasis is mostly seen in children and young adults and causes small, pink notes on the skin. The spots appear on the truck, upper arms, thighs, and scalp.

Triggered by an upper respiratory or bacterial infection (i.e. strep), stress, skin injury ,and certain medications, this type of psoriasis goes away on its own without treatment within a few weeks without medication.


Inverse psoriasis shows up as bright red, smooth, and shiny spots, under the breasts, in the groin area and/or the skin folds around the buttocks and genitals, and under the arms. Sweating and rubbing worsen inverse psoriasis and yeast build up is a trigger.


Pustular psoriasis is rare but it is mostly seen in adults. It causes pustules (pus filled bumps) surrounded by inflamed skin on the hands and feet, but it may cover most of the body in rare and very serious cases.

Pustular psoriasis covering the entire body is called generalized pustular psoriasis and causes fever, chills, nausea, muscle weakness, and fast heart rate. Triggers include topical and steroid medications, too much ultraviolent light, pregnancy, stress, infection, and chemical exposure.


Erythrodermic psoriasis is rare but it is a very serious condition affecting most of the body, causing skin to appear burned. It also causes severe itching, burning and peeling, a fast heart rate, and body temperature changes. These symptoms might warrant emergency attention and as they can result in infection, pneumonia, or heart failure.

This type of psoriasis is triggered by sudden stopping of psoriasis treatments, allergic drug reaction, severe sunburns, infections, and some medications. It may also occur if your psoriasis is difficult to control.
