Spongiotic Dermatitis: Symptoms, Causes, Treatments

Spongiotic dermatitis (SD) is a blanket term that helps describe specific histopathology (change in tissues) of atopic dermatitis, contact dermatitis, and other eczema-related conditions. Stay with me here, I am going to break it down! 

The word Spongiotic is really just excess fluid, which can cause swelling. 

An easy way for me to remember the term is that Spongiotic looks like it has the word “sponge” in it, which can have an excess of fluid

Sometimes SD is just referred to as dermatitis. The National Library of Medicine defines spongiotic dermatitis as “A chronic inflammatory skin condition characterized by itchiness and a rash in the chest and abdominal areas.”

Causes of spongiotic dermatitis

Scientists have yet to find the definitive cause of SD, but here is what is known to be related. The more common causes of SD are nummular eczema, allergic/irritant dermatitis, and occasionally drug reactions. 

Fun fact: SD can resemble a fungal infection, so it is important to see your doctor or a dermatologist for a proper diagnosis. 

There are no specific conditions that point directly to the cause, so it is important for your provider to get a thorough medical history. Here are the triggers that may invoke spongiotic dermatitis. 

List of  Potential Spongiotic Dermatitis Triggers 


Medications that can trigger spongiotic dermatitis include topical steroids, antimalarials, nonsteroidal anti-inflammatory drugs (NSAIDs), and immunosuppressants. When these medications are used, they can cause the walls of the skin cells to weaken, allowing fluid to leak out.

In addition, these medications can inhibit the production of substances that help to keep the skin moist and supple. As a result, the skin becomes dry, cracked, and inflamed. In severe cases, spongiotic dermatitis can lead to blistering and ulceration.


Infections are one of the most common triggers for this condition, as they can cause the immune system to go into overdrive. Once an infection has resolved, the symptoms of spongiotic dermatitis will typically resolve on their own. However, in some cases, the condition may recur or become chronic.


When a person is under a lot of stress, their immune system can become weakened, making them more susceptible to skin problems. In addition, stress can also cause hormonal changes that can further contribute to skin inflammation. As a result, managing stress levels is often an important part of treating and preventing spongiotic dermatitis.

How is it diagnosed?  

According to the Cambridge University Press, spongiotic dermatitis is diagnosed as follows. First, SD is excess fluid (edema) under the skin, so your doctor may diagnose simply by your symptoms, health history, and how your skin looks. To get a true diagnosis of SD a skin biopsy is usually performed. The biopsy is sent to a pathologist to be examined under a microscope.

The pathologist will be able to determine what type of skin disorder is present and its severity.  SD can be diagnosed into subclasses of acute, subacute, and chronic. 

Acute: Short-term condition with a sudden onset, and may or may not resolve on its own. 

Subacute: A condition that is not acute, but not yet chronic. 

Chronic: Long-lasting condition that doesn’t go away, or keeps coming back. 

The results from the biopsy will be documented and sent to your provider. A follow-up appointment is usually required to go through the results as well as discuss any potential treatment plans.  

Can Spongiotic Dermatitis Go Away? 

Technically yes. Medical professionals believe that spongiotic dermatitis is caused by food allergies, insect bites, or even medications. By removing the allergen exposure your symptoms of SD should go away. But if you are exposed to that allergen again, you will more than likely develop SD symptoms again. 


The outlook of SD depends on the cause, severity, and whether the condition is considered acute, subacute, or chronic. Overall, the outlook is good with most cases being manageable. Of course, there are cases where you may have a bad flare-up which can lead to other complications including infections. 


Complications may arise when managing spongiotic dermatitis, here are some complications you should be aware of. Many times the cause of complications is due to symptoms that are not well managed or continue to get worse regardless of proper treatment and prevention techniques. 

Complications can become quite serious, so always consult with your medical provider regarding your condition. 

Broken skin

Scratching, trauma, and swelling can lead to the skin breaking open. When the skin is broken, you may notice bleeding, or weeping of liquid from your skin. Broken skin can cause complications by potentially limiting your range of motion (bandages, scabs, etc.) or by making you vulnerable to infections. 


Infection is a possible complication from spongiotic dermatitis. Here are some signs of infection that you should be aware of.

Signs of infection 

  • Blister-like sores
  • Crusting skin
  • Excessive swelling
  • Skin is hot to the touch
  • Symptoms get worse, not better
  • Weeping or puss 
  • You develop a fever

Infections are a condition that needs treatment. Seek medical assistance right away if you suspect an infection. Keep in mind this is not an all-inclusive list and you may experience different symptoms. When in doubt, see a medical professional. 

How’s it treated?

The good news is there are treatment options for spongiotic dermatitis symptoms. Treatment options are something you should be discussing with your doctor. Ultimately, this is an inflammation of your skin, so knowing the cause can be great information to have when starting a treatment plan.

For example, if the known cause of spongiotic dermatitis is allergies, avoiding those allergens or taking an antihistamine (treatment) can help with removing the symptoms.

A medical provider may suggest one of these treatment options, after this list of options you will find more details for each one below.

Spongiotic Dermatitis Treatment Options

  • Antihistamines
  • Creams
  • Lotions
  • Ointments
  • Topical steroids
  • Prescription medications
  • Home remedies


Antihistamines work by lowering the amount of histamine in your body. Histamine is your body’s allergic response to something. If your dermatitis is caused by an allergic reaction, an allergy medication could help relieve your symptoms.


Creams usually contain a mix of oil-based moisturizers and a mix of water-based moisturizers. Keeping your skin moist may help in relieving itching, and dry flaky skin.


Lotions are mostly water-based and provide a short-term moisture fix for your skin. If you need a lightweight moisturizer that isn’t greasy and you are able to apply it multiple times a day, lotion may be the best option for you.


Ointments are the thickest and oil-based (usually petroleum jelly) but they provide the longest-lasting moisture. They are greasy, but they work! My recommendation would be to reserve using ointments for bad flare-ups, or as a treatment that you apply to your skin at night.

Topical steroids

Topical steroids do really well at calming down the skin and easing inflammation. They are also good at stopping the itch while also providing some moisture to your mad skin. The strongest over-the-counter topical steroid is Cortizone 10® which contains 1% hydrocortisone. If you need a stronger topical steroid you will need a prescription.

Prescription medication

The prescription medicine world has an overwhelming amount of choices when treating SD. According to Drugs.com, there are 161 different medications that can be used for treating spongiotic dermatitis. Here are the categories of drug treatments that you can discuss with your doctor.

Spongiotic Dermatitis Prescription Drug Classes
  • Anorectal preparations
  • Antihistamines, topical
  • Anti-infectives, topical
  • Glucocorticoids
  • Emollients, topical
  • Miscellaneous topical agents
  • Rubefacients, topical
  • Steroids, Topical
  • Topical steroids with anti-infectives

Home remedies for Spongiotic Dermatitis

Home remedies are a great place to start when managing symptoms of spongiotic dermatitis. Here are some options that may work for you. Keep in mind that everyone reacts and has slightly different symptoms, so these may or may not work for you.

Rethink your Shower

Showering or bathing can be relaxing, but if you suffer from spongiotic dermatitis, you may dread rinsing. Here are some pointers to keep your skin calm and potentially improve your symptoms.

Showering with Spongiotic Dermatitis
  • Avoid hot showers, turn down the temperature a bit
  • Make it a quick shower, under 10 minutes is ideal
  • Pat your skin dry, don’t drag the towel across your skin
  • Immediately apply your favorite hypoallergenic moisturizer
Use a Moisturizer

Not all moisturizers are created equally, you will want to use a moisturizer that doesn’t have a laundry list of items you cannot pronounce, or that is heavily scented. Moisturizers actually have categories which are lotions, creams, and ointments.


Dermatitis has a track record of being caused by allergens (not all the time), so you may benefit from using an antihistamine as a home remedy. If you suspect that your spongiotic dermatitis is caused by an allergen, an antihistamine will help calm the immune system which should calm down your mad skin.

Topical Steroids

A topical steroid like hydrocortisone may get you the relief you need, and you may already have it on hand at home. Hydrocortisone works really fast as you directly place it on your inflamed skin. The steroid cream packs a punch to ease the inflammation.

It’s worth a shot if you haven’t tried it already, and if it doesn’t work out, luckily the cream can be used for other ailments like bug bites, itchy skin, and sunburn.

Prevention of Spongiotic Dermatitis

Preventing flare-ups to limit symptoms is a great approach when managing SD.  The first step you should take is to know your triggers and avoid those triggers if possible. Above all, if it is not possible to avoid your triggers there are still some things you can do to hopefully make life a bit easier.

Apply moisturizer

When managing SD, moisturizers are going to become your best friend. The goal is to keep you and your skin happy and healthy. Healthy skin leads to fewer flare-ups and more mild symptoms. Therefore, when you choose a moisturizer, the more natural and fewer additives the better. For example, moisturizers with fragrances are a big “no-no”. Fragrances smell nice, but they tend to be major skin irritants. 

Lower the Shower Temperature

Interestingly, our skin is sensitive to extreme temperatures, both hot and cold. When you have SD or any other skin condition, this sensitivity is amplified. To prevent flare-ups, lower the shower temperature, especially if you usually have it hotter than the surface of the sun (ladies).

Additionally, professionals recommend limiting the amount of time in the shower and to apply moisturizer within the first two minutes of getting out. Applying moisturizer right away helps your skin lock in moisture. 

Ditch Harsh Skin Products

There are so many harsh products that we expose our skin to every day, and we might not even be aware! If you haven’t heard of the Environmental Working Group (EWG), you have to check it out. They have health ratings on many daily-use products.

Our family was shocked at how many “F” graded products we were using.

We have now switched to healthier choices with better ratings. Here are some products that I recommend you look into. 

Products that may be irritating your skin 

  • Shampoo
  • Conditioner
  • Body wash
  • Handsoap
  • Dish soap 
  • Bar soap
  • Shaving cream
  • Laundry detergent 
  • Fabric softener 
  • Dryer sheets
  • Face wash
  • Cosmedics 
  • Lotion
  • Sunscreen
  • Air fresheners 
  • Household cleaners

For us, the worst products we were using were laundry detergent and household cleaners. Because of this, we have since switched to healthier products and we replaced ALL our household cleaners with Force of Nature Cleaner.

force of nature cleaner replaces all of these cleaners: bleach, 409, scrubbing bubbles, windex, resolve, febreeze.
