Papular urticaria is a common skin condition characterized by raised, red, itchy bumps on the skin. It is more common in children than in adults.
While papular urticaria can sometimes be confused with other diseases, we will discuss the diagnosis and treatment of papular urticaria and how it differs from other diseases associated with skin rash.
What Are the Symptoms of Papular Urticaria?
Papular urticaria typically presents as small and dome-shaped lesions, often in a symmetrical pattern all over the body. The lesions may be grouped on exposed areas, particularly the back of the hands, arms, and forearms or the shins and thighs.
Despite its name, it is not a true urticaria.
There may also be itchy wheals (small red spots) and swelling that appear from hours to days after the first lesion associated with constant scratching that may make it worse and feel tight and itchy.
In some cases, these symptoms may be accompanied by fever or other flu-like symptoms. It is important to seek medical attention if you experience any of these symptoms as they can be indicative of a more serious underlying condition.
What Are the Common Causes of Papular Urticaria?
Papular urticaria is a hypersensitivity reaction to the bites of mosquitoes, fleas, bedbugs, and other insects. There is immunologic hypersensitivity, specifically to the saliva of the biting insect.1
Whether you will develop papular urticaria may depend on a variety of factors, including environmental exposure, immune function, and individual sensitivities.
Papular urticaria is neither hereditary, nor contagious.
While there may be a genetic component to some aspects of these factors, such as immune function, there is no evidence to suggest that papular urticaria is directly passed down from parent to child.
It’s important to note that papular urticaria is not contagious, so you don’t need to worry about passing it on to others. However, if you do have the rash, it’s a good idea to avoid scratching it, as this can lead to infection and scarring.
Diagnosing and Treating Papular Urticaria
If you think you might have papular urticaria, the first step is to see a dermatologist for a diagnosis. They can usually identify the rash just by looking at it without ordering any additional tests if the lesions have appeared recently within the last 6 weeks.
Any additional tests are ordered to find out any underlying medical cause or autoimmune cause of urticaria which can be corrected in case the lesions last for more than 6 weeks.
A skin biopsy is usually not recommended unless the rash does not resolve with conventional treatments, is associated with some systemic symptoms like fever, joint pains, sore throat, cough, etc., or to rule out other conditions that might be causing papular urticaria.
Once you have a diagnosis, there are several treatment options available.
Preventing and Managing Papular Urticarial Flare-Ups
If you’re someone who suffers from this itchy rash, you know how frustrating it can be to deal with. But with some simple strategies, you can minimize your symptoms and keep your skin healthy.
- Avoid getting bitten: Since papular urticaria is caused by insect bites, it’s important to take steps to avoid getting bitten in the first place. This might mean using insect repellent, wearing long sleeves and pants when outdoors, and avoiding areas with high insect activity especially if you’re planning to spend time outside.
- Get rid of insects: You should contact your local pest control firm to get rid of insects, especially bed bugs.
- Resist the urge to scratch: Scratching can not only make the rash worse, but it may produce erosions and ulcerations or increase your risk of infection. Instead, try using a cold compress or taking an antihistamine to alleviate the itching.
- Caring for your skin: Another important aspect of preventing and managing papular urticaria is taking care of your skin. Make sure to:
- Keep your skin moisturized and hydrated, as dry skin can exacerbate itching and inflammation
- Avoid using harsh soaps or skincare products that can irritate your skin
- Wear loose-fitting clothing that won’t rub against your rash.
If your symptoms are severe or persist despite these measures, it’s a good idea to see a dermatologist. They can recommend stronger treatments, such as prescription-strength antihistamines or topical steroids, to help manage your symptoms.
Papular urticaria is self-limiting.
Sometimes doctors can’t figure out what’s causing a person’s papular urticaria. But the good news is, most people eventually grow out of it! This might happen because they get used to being bitten by bugs over time.
So, it’s important to be patient and gentle with your skin and to work closely with your dermatologist to develop a personalized treatment plan that works for you.
