Perivascular dermatitis, a skin condition marked by inflammation surrounding the blood vessels, can lead to more than just cosmetic concerns. This type of dermatitis is not typically dangerous but can be associated with underlying systemic diseases in a minority of cases. Patients often experience symptoms such as rashes, flaking, and dry skin along the paths of the affected vessels. 

While the prevalence of perivascular dermatitis is not well-documented, skin diseases as a whole affect millions, with the American Academy of Dermatology reporting that about 5.1 million Americans seek treatment for skin disease annually. Understanding the implications and management of perivascular dermatitis is crucial for those affected, ensuring they can maintain their skin health and overall well-being.

People may experience this dermatological problem anywhere on the body, but the face, hands, feet, and arms are common locations for this condition. Treatment options are variable and include fairly conservative choices and more invasive techniques for managing skin irritation.

The condition may or may not be associated with changes in the layers of the skin (epidermal changes). Edema of the skin layer dermis is frequently seen in advanced cases of dermatitis. In addition to the vessel walls swelling (endothelial cells), there is the disintegration of the vascular walls.

Dermatitis is a generalized term that refers to the inflammation of the skin. There are different types of dermatitis, with atopic dermatitis, contact dermatitis, and seborrheic dermatitis being the most prevalent ones. Perivascular dermatitis is skin inflammation with the involvement of blood vessels of the skin.

Types of Perivascular Dermatitis

Perivascular dermatitis is classified into superficial and deep types. As the name indicates, the superficial type affects the skin’s blood vessels. On the other hand, deep perivascular dermatitis involves all vessels-superficial and deep. Therefore, superficial perivascular dermatitis is more common than the deep type.

In most cases, clusters of white blood cells (lymphocytes) aggregate and cause skin inflammation, i.e., dermatitis. In the early stages of the disease, there is infiltration of small blood cells, neutrophils, and eosinophils. Later on, lymphocytes migrate to the site. 

Causes of Perivascular Dermatitis 

On analysis of patients, physicians have concluded that the disease is idiopathic or often has unknown causes. There appears to be a genetic predisposition for perivascular dermatitis, although not all patients have a family history of the disease. 

However, the disease can occur when the area around the blood vessels becomes inflamed. That can be attributed to allergic responses or irritation like being exposed to coarse fabrics. 

Infections can also trigger inflammation around vessels. Dermatitis can be genetic. However, other common causes include overreactions by the immune system, environmental factors like air pollutants or fragrances, and exposure to certain chemicals.

Underlying auto-immune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, Sjorgen’s syndrome, etc., are risk factors for perivascular dermatitis. Certain drugs such as anticonvulsants, antipsychotics, and antibiotics may also trigger the disease. In addition, researchers believe that influenza vaccines and interferons can also trigger the disease.

Studies have shown there is a direct link between psychological stress/anxiety and the occurrence of dermatitis. Other causative factors for perivascular dermatitis include hormonal changes. As per studies, there exists a connection between hormonal level (sex hormones) changes and dermatitis.

Prone patients may develop skin disorders when exposed to irritants (environmental, chemical, etc.). On exposure, the skin develops redness, swelling, and itching, and it may take days or weeks to resolve, especially if the patient continues to be exposed to the irritant.

Perivascular dermatitis is linked to a skin condition of babies and infants, i.e., Gianotti Crosti syndrome. The syndrome is characterized by the formation of itchy blisters on the skin of arms and legs. 

How Long Does It Take for Dermatitis To Go Away? 

Like most forms of dermatitis, perivascular dermatitis also goes away by itself. However, patients should consult a dermatologist if the condition persists for a long time or interferes with their daily activities. 

Generally, the disease goes away within 2 to 4 weeks, but the duration may vary for different individuals depending on the age, comorbid conditions, and extent of the disease.

Home Remedies To Manage Dermatitis 

Some measures for treating perivascular dermatitis include changing the diet, wearing different clothing, and being especially alert to skin irritation in the heat and during exercise sessions. Adding dietary supplements, like vitamin D supplements, can be a fruitful step. A meta-analysis shows that vitamin D can improve dermatitis conditions.

Topical and oral medications can also be prescribed to reduce inflammation and swelling. Some patients find lotions and hydrocortisone creams to soothe the skin, along with cool compresses to address the heat of inflammation. In addition, the application of a cool, wet cloth provides relief. Oral antihistamines can also be helpful. 

A warm bath with a baking soda mixture is an effective home remedy. The solution helps alleviate symptoms of dry skin and dermatitis. You can also find medicated shampoos in the market to symptomatically manage your condition. A dilute bleach bath- vinegar mixed in warm water soothes the skin and improves the symptoms. 

If the problem persists, scrapings may be taken to look for infection, and patients can consider options like allergy testing and an elimination diet to find out what, exactly, they are reacting to.

Precautions To Be Taken 

Patients should follow precautions to prevent further aggravation and the spread of the rashes. The most basic step to be taken is to avoid scratching and rubbing the area. Covering the dry skin with dressing can keep patients from scratching again and again. Patients must ensure that the clothing is not scratchy or rough. 

Patients should use unscented mild laundry detergents to wash clothes, sheets, and towels that have come in contact with affected skin. In cases of allergic responses, it is crucial to identify the specific allergen. Once identified, patients must stay away from the environmental allergen.

A crucial step in the prevention of perivascular dermatitis is managing stress levels. Emotional stress is identified as a direct cause of some types of dermatitis. Therefore, prone individuals must adopt some relaxation and meditation techniques. For example, yoga is an effective way of lowering anxiety and stress levels in the body.

Patients with perivascular dermatitis may find that their skin irritation attracts unwanted attention from people around them. It can be helpful to remind people that dermatitis is not contagious and that it is not dangerous to touch someone who has this condition. 

Soothing creams can minimize the appearance of inflammation to keep patients more comfortable in social settings, and some people may also use makeup. Although, makeup can increase irritation and prolong healing times.

Patients who experience recurrent perivascular dermatitis despite taking reasonable precautions like avoiding allergens may want to see a dermatologist, and perhaps an immunologist, for further evaluation. There may be another underlying problem that has not been addressed, and treating that could be necessary to resolve the skin irritation. 

Patients with this condition should also ensure it is noted in their charts, so care providers know to watch out for it. If they experience skin irritation in reaction to medications, it is crucial to confirm that prescriptions and over-the-counter medications do not contain any reactive ingredients.

FAQ on Perivascular Dermatitis

What is perivascular dermatitis?

Perivascular dermatitis is a skin condition characterized by inflammation around the blood vessels in the dermis, the skin's second layer. This inflammation can be caused by various factors, including autoimmune disorders, infections, or allergic reactions. Symptoms often include redness, itching, and sometimes lesions or rashes. Diagnosis typically involves a skin biopsy, where a sample is examined under a microscope to observe the characteristic patterns of inflammation around the blood vessels.

What causes perivascular dermatitis?

The exact cause of perivascular dermatitis can vary, but it is often associated with underlying conditions such as psoriasis, lupus, or dermatitis herpetiformis. It can also be triggered by infections, medications, or allergens. According to the American Academy of Dermatology, conditions like psoriasis affect up to 7.5 million people in the United States, and perivascular dermatitis can be a manifestation in some of these cases (https://www.aad.org/media/stats/conditions/skin-conditions-by-the-numbers).

How is perivascular dermatitis treated?

Treatment for perivascular dermatitis focuses on addressing the underlying cause and reducing inflammation. Topical corticosteroids are commonly prescribed to alleviate symptoms. In cases where an allergy is identified, avoiding the allergen is crucial. For more severe or persistent cases, systemic treatments such as oral corticosteroids, immunosuppressants, or biologics may be considered. A dermatologist will tailor the treatment plan to the individual's specific condition and needs.

Can perivascular dermatitis be cured?

While perivascular dermatitis can often be managed effectively with treatment, it may not be curable, especially if it is linked to a chronic underlying condition. Management strategies aim to control symptoms and prevent flare-ups. Long-term treatment and regular follow-up with a healthcare provider are important to keep the condition in check and adjust treatment as necessary.

Is perivascular dermatitis contagious?

No, perivascular dermatitis is not contagious. It is an inflammatory reaction within the skin and does not spread from person to person. The condition is related to the individual's immune response or other underlying health issues, and its presence does not pose a risk of transmission to others.

I just found out that my 9 year old daughter has it. So this is all new to us.

@nony - I’ve never had anything like this condition. I did, however, spend a day at the beach once without applying lotion to my scalp. I applied it to the rest of my body, but not to my scalp, and I am half bald.

I got burned so bad that it appeared I had all the conditions of scalp dermatitis. There was the redness, peeling and flaking skin, and that petulant itch. Some people actually thought I had the disease when I returned back to work but I had to explain that it was sunburn.

It’s hard to cover that stuff up when it’s on your scalp, so I understand how these people must feel.

@MrMoody - Well, it’s certainly not leprosy, but if you are afflicted with the condition in a part of the body that is plainly visible for others to see, I think you would certainly feel like an outcast.

It’s good to know that at least the condition is not contagious, so that you can continue to interact with other people without fear of spreading the disease.

MrMoody

I’ve seen dermatitis pictures before and they are horrifying to look at, for me anyway. People who suffer from this condition have what appears to be an almost leprous condition in some cases.

I know it’s not that bad, but the breakout and redness is awful. I can’t imagine what it must be like to have that condition and try to cover it up with cream and stuff like that.

I think the hardest part, in addition to the discomfort you would feel in public, is to continually resist the temptation to scratch the affected area. If you keep scratching it, the condition will only get worse and the infected area would spread I think.
