Are you experiencing sudden, severe skin lesions? Let's learn about Pyoderma Gangrenosum!

Have you ever had a small blister or red spot on your skin that started out as a small blister or red spot and suddenly turned into a large, painful ulcer? It can happen in more than one place, but it can also happen in several places on your body. This is actually a condition that requires some attention and can be a bit complicated. Today we are going to talk about a skin condition called Pyoderma Gangrenosum, which is a rare but very important condition to be aware of. Don't worry, let's keep it simple.

What is this Pyoderma Gangrenosum?

Simply put, pyoderma gangrenosum is a chronic , meaning long-lasting, and recurring skin condition. What happens is that your skin first starts to develop small, discolored (maybe red, purple, blue, brown, or black) blisters, or fluid-filled blisters (bullae). What's more dangerous is that these can quickly grow larger, coalesce, and become deep, open sores (ulcers) .

Imagine what it would be like if something started out as a small pimple and within a few days it turned into a painful ulcer the size of a nickel? That's what happens here. Some people may only get one ulcer, but in severe cases, multiple ulcers may develop at once. These ulcers can be very painful .

Importantly, pyoderma gangrenosum is often associated with other systemic diseases , meaning it is not just a skin problem.

Who is most likely to get this?

Pyoderma gangrenosum can occur at any age, but it is very rare in children . It is most common in women between the ages of 20 and 50. You may also be more likely to develop pyoderma gangrenosum if you have any of the following conditions:

• Rheumatoid arthritis - This is a disease that causes inflammation of the joints.
• Ulcerative colitis - An inflammatory condition with ulcers in the large intestine.
• Crohn's disease - Another inflammatory condition that occurs in the digestive tract.
• Some types of cancer, for example, blood cancers such as leukemia or lymphoma.

It's said to occur in about one in a hundred thousand people in the United States . That means it's not that common.

How does this affect the body? What are the symptoms?

Pyoderma gangrenosum causes small, discolored blisters and inflammation, meaning swelling and redness, on your skin. These blisters can appear anywhere on the body, but they are most often seen on the legs, ankles, and feet (lower extremities) .

These blisters can quickly burst, turn into large, painful ulcers, and spread.The main symptoms are:

• Small, discolored (red, purple, blue, brown, or black) pus-filled blisters. These quickly enlarge .
• Open sores (ulcers) develop. The edges around these sores are raised and clearly visible .
• Swelling and severe pain around the wound.
• Some people may get a fever .
• Joint pain may also occur.

These wounds can sometimes be very large and deep , and the pain can be unbearable.

Some studies have shown that up to 70% of people with pyoderma gangrenosum may have more than one other condition (comorbidities) at the same time. When pyoderma gangrenosum is combined with other conditions, it is said that the risk of death can increase by up to 30%. Therefore, this is not something to be taken lightly.

Is this an autoimmune disease?

Yes, pyoderma gangrenosum is believed to be an autoimmune disease . Simply put, your body's own defense system, the immune system, attacks your own skin cells. For some people, pyoderma gangrenosum resolves when the other conditions mentioned above are treated.

Why does pyoderma gangrenosum develop?

Medical experts still don't know the exact cause , but more than half of people with pyoderma gangrenosum have other conditions (such as arthritis, leukemia, and Crohn's disease), as mentioned earlier.

In addition, pyoderma gangrenosum can also occur after a skin injury, abrasion, or surgery (pathergy) . Imagine a small abrasion on your hand, or a minor surgery, and this is where this disease can start. Sometimes these wounds also develop around a stoma site after surgery. This is called peristomal pyoderma gangrenosum.

Is this contagious?

No. Pyoderma gangrenosum is not contagious . It cannot be spread from one person to another through skin-to-skin contact. This is a concern that many people have, so it is important to be clear about this.

How do doctors recognize this?

To be honest, diagnosing pyoderma gangrenosum can be a bit challenging . There is no definitive test that can confirm that it is the condition. Therefore, doctors usually do tests to rule out other conditions that can cause similar skin problems. That is, they first make sure that other conditions that have similar symptoms are not present. For example:

• Various infections.
• Skin cancers.
• Blood vessel inflammation of the skin.
• Lupus disease.
• A condition called Sweet syndrome.

Tests for this may include:

• Blood tests.
• Taking a small piece of skin for examination (Biopsy).
• Bone marrow sampling - especially if things like blood cancer are suspected.
• Proctoscopy.
• Colonoscopy - if conditions such as Crohn's disease are suspected.

Only after all these tests have been done and everything else has been ruled out does the doctor conclude that it is pyoderma gangrenosum.

What are the treatments?

There are several treatment options for pyoderma gangrenosum. Early diagnosis and treatment are important to prevent scarring .

Treatment for common, less severe cases

If the wounds are not too severe, the doctor may prescribe topical creams or ointments. These include:

• Corticosteroids: These are drugs that reduce inflammation. They can be applied to wounds as a cream or taken as pills. Examples: cortisone, prednisone. However, these can have side effects such as increased appetite, weight gain, mood swings, acne, and insomnia.
• Nonsteroidal anti-inflammatory drugs (NSAIDs): These are pain relievers. Examples: aspirin, ibuprofen. These can cause gas , bloating, stomach pain, nausea, vomiting, diarrhea, and constipation.
• Silver sulfadiazine skin cream: This is actually an antibiotic cream that is applied to burns to prevent infection. It is sometimes used for this condition as well. It can cause itching, fever, chills, skin lesions, and sensitivity to sunlight.

A little harsh?

If the injury is more severe, the doctor may prescribe treatments like these:

• Immunosuppressant medications: These work by reducing the ability of your immune system to damage its own body. Examples: mycophenolate, cyclosporine.
• Biologic agents: These are newer types of drugs. They work by targeting specific proteins in the body that cause inflammation. Examples: infliximab, adalimumab, ustekinumab.
• Hyperbaric oxygen therapy: This involves administering 100% oxygen inside a special chamber. It is said to speed up the healing of body tissues.

Let's also learn about surgery.

In some cases, surgical removal of dead tissue from the wound (debriding) may be helpful. However, this also has risks .Because skin damage (pathergy) can worsen the symptoms of pyoderma gangrenosum, this should be done with great caution and at the discretion of your doctor.

Sometimes a skin graft can be performed. This means that skin is taken from a healthy part of the body and transplanted to the wound site.

What do you need to know as a person with this condition?

If you have pyoderma gangrenosum, any kind of trauma to your skin – cuts, scrapes, bruises – can make your symptoms worse . So you need to be as careful as possible. Imagine you're working in the garden or in the kitchen, and even a small scratch can become a big problem.

Also, keeping wounds clean is essential to prevent infection .

• Wash the wounds thoroughly with clean, running water and soap.
• Then, carefully cover the wound with a nonadhesive bandage. This will prevent dirt and germs from entering.
• Your dermatologist will give you more information about how to keep the wound clean and how to apply bandages. Follow those instructions carefully.
• If you have been given an ointment, wash the wound, apply the ointment, and then bandage it.

For severe wounds, your doctor may recommend a hydrocolloid bandage . These protect the wound from further rubbing and infection. They will "melt" into the skin within two to three days.

How long does it take to heal?

Pyoderma gangrenosum is a difficult condition to treat . Even with proper treatment, the wounds can take weeks, sometimes months, to heal. Therefore, you need to be patient.

Can this be prevented?

Since the exact cause is unknown, it is difficult to say for sure how to prevent it . However, if you have risk factors such as leukemia or inflammatory bowel disease, and you develop any new skin problems (especially sores that grow quickly) , tell your doctor right away . Ask your doctor to refer you to a dermatologist or other specialist who has experience with pyoderma gangrenosum.

When should I see a doctor?

You should definitely see a doctor in these cases:

• If you have inflammatory bowel disease, arthritis, or a blood disorder and develop blisters or sores that get bigger quickly .
• If your wound looks infected (red, purple, gray or white, swollen, or painful).
• If you develop new symptoms .
• If you experience severe side effects after taking the medication.

Important questions to ask your doctor

When you go to see the doctor, it is very important to ask these questions:

• How exactly do you say I have pyoderma gangrenosum?
• If I don't have pyoderma gangrenosum, what other skin disease could it be?
• What kind of tests are you hoping to do?
• What kind of medication or treatment do you recommend?
• Can you give me some cream to apply or some medicine to drink?
• What is the full list of side effects of these medications and treatments?
• What else should I do to reduce my symptoms?
• Should I see a dermatologist, plastic surgeon, gastroenterologist, immunologist, or other specialist?

It is very important to ask these questions and gain a clear understanding of your situation.

What is the difference between Pyoderma Gangrenosum and Ecthyma Gangrenosum?

These two names are somewhat similar, so they can be confused.

Ecthyma gangrenosum is a rare skin infection caused by Pseudomonas bacteraemia, a bacteria commonly found in water and soil. It can also cause skin lesions and necrosis of surrounding tissue. It most commonly affects people with weakened immune systems .

Pyoderma gangrenosum also causes skin lesions. The exact cause is unknown. It is thought to be an autoimmune disorder. However, it is not primarily a condition that affects people with weakened immune systems .

Are there different types of pyoderma gangrenosum lesions?

Yes, there are four main types of pyoderma gangrenosum lesions:

• Classic pyoderma gangrenosum: This is the most common type. Painful sores usually develop on the legs.
• Atypical or bullous pyoderma gangrenosum: This type appears as fluid-filled blisters. It is usually seen on the hands. It is more common in people with leukemia.
• Pustular pyoderma gangrenosum: Appears as small, pus-filled blisters (pustules) on the hands and feet. This is more common in people with inflammatory bowel disease.
• Vegetative pyoderma gangrenosum: This type of lesion is usually not painful.

Finally, things to remember

Pyoderma gangrenosum is a condition that starts as small blisters on the skin and can quickly turn into large lesions. It can be difficult to diagnose and treat , so both you and your doctor need to be patient.

Remember, it's very important to be careful of any trauma to your skin, as this can lead to new lesions.

If pyoderma gangrenosum is severe and you have other comorbidities, it can cause severe pain, scarring, and even life-threatening complications. Therefore, if you have an autoimmune disease and are experiencing skin lesions that grow rapidly, seek medical attention immediately. Early detection and treatment can help you get better. Don't panic , but be careful.
