Perivascular Dermatitis
A Quick Guide to Perivascular Dermatitis
Dermatitis is a skin condition and perivascular dermatitis is one of the most common types. The only difference between this and other types of dermatitis is that it occurs within the perimeter of the blood vessels. It is caused, like all forms of dermatitis, by skin allergens and irritants. Any combination of genetic and environmental factors can bring on episodes of perivascular dermatitis.

Because perivascular dermatitis has genetic causes, there is no way to prevent the skin condition. You can, however, with the help of your physician, find ways to manage the symptoms, which include much intense itching as well as inflammation and other annoying complaints. You can also control, at least to a certain extent, the environmental concerns, such as various allergens that present themselves indoors and outdoors.
Allergens can include all sorts of household, yard and garden products, such as soaps, solvents, shampoos, cleansers, insecticides, etc. You can manage which of these products you use and how you use them. While you can’t do much about the genetics or yeast that causes all forms of dermatitis, you can pick and choose among chemicals, which can be irritants or allergens which are thought to aggravate the condition.

Treatment for perivascular dermatitis includes many different topical options. You and your doctor should discuss which ones might be appropriate for you. These include corticosteroids, hydrocortisone, selenium sulfide, zinc pyrithione, and ketoconazole. These are meant to reduce swelling and control the flaking and itching, which can be almost unbearable. The worst thing you can do is scratch a patch of dermatitis, because all this does in increase the inflammation and make it raw, so that then it is in danger of becoming infected.
Perivascular dermatitis comes and goes like many other skin conditions and there is no definite way to know when or why it might reappear. Because it is a condition which is related to blood vessels, this type of dermatitis is most often going to occur on the toes, fingers, hands, feet, legs, arms, face and head. Some doctors believe that exposure to UVB and UVA rays can stop the yeast that causes dermatitis from growing. But, the practice is risky, considering that other medical practitioners advise patients that exposure to sunlight increases the chances of developing perivascular dermatitis.
So, it seems that there is a catch-22 when it comes to exposure to ultraviolet rays. Unfortunately, perivascular dermatitis is a chronic condition. That will, however, give you more opportunities to find out what works or does not work for you. Because you can do nothing to prevent perivascular dermatitis from happening, it is important to find methods that can best control the symptoms so that you can have a little peace of mind.
Unless you have had dermatitis or another similar skin condition, it is impossible for you to know the intensity of the itching or of the painful condition that can come from an inability to stop scratching. In order to get proper rest at night and be able to get through daily activities, you will need to get the right treatment to end the symptoms and heal up the area. It also depends on where the dermatitis is located as to how hard it is to get it healed up. A patch of perivascular dermatitis on the bottom of your foot, for example, is going to be harder to heal than one on your arm because you have to walk on your foot every day.
If you have this or any other form of dermatitis, see your doctor to explore treatment options. He or she may send you to a specialist--a dermatologist--if you have a particularly bad or advanced perivascular dermatitis.
