When a young child develops a persistent rash around the mouth along with itchy, red patches on the arms, parents may assume both conditions are caused by the same problem. However, facial rashes and body eczema can have different underlying causes and may require different treatments.
Recently, a 4-year-old girl visited Village Dermatology after experiencing a flaky, itchy rash around her mouth for approximately one month and persistent red, itchy patches on both arms for several months.
Her mother had been applying hydrocortisone cream and moisturizers to help manage the irritation. She had also eliminated tomato-based foods from her daughter's diet to see whether the facial rash would improve.
Despite these efforts, small bumps and flaking remained around the child's mouth.
Her mother's concern raised an important question:
“Why does my daughter keep getting a rash around her mouth and eczema on her arms, even though we're using hydrocortisone?”
After a focused dermatologic examination using dermoscopy, our dermatology team identified two distinct conditions:
Perioral dermatitis: An inflammatory facial rash involving the skin around the mouth.
Atopic dermatitis (eczema): A chronic inflammatory skin condition affecting the inner elbows.
Because these conditions require different approaches, the dermatologist recommended Elidel (pimecrolimus) 1% cream for the facial rash and fluocinolone 0.01% body oil for eczema flare-ups on the arms.
Here's what parents in Houston and Katy, Texas, should know about childhood perioral dermatitis, eczema, and appropriate skin care.
What Causes a Persistent Rash Around a Child's Mouth?
Perioral dermatitis is an inflammatory skin condition that commonly produces small bumps, redness, dryness, and flaking around the mouth.
Although it is frequently diagnosed in adults, perioral dermatitis can also affect young children.
Common symptoms include:
Small pink, red, or skin-colored bumps around the mouth
Dry or flaky skin
Mild itching or burning
Persistent irritation
Recurrent flare-ups despite moisturizers
A rash that may worsen with certain topical products
In this patient's case, the dermatologist observed small bumps and flaking around the mouth, consistent with perioral dermatitis (ICD-10: L71.0).
The diagnosis was favored based on the appearance of the rash and the patient's history.
Can Hydrocortisone Make Perioral Dermatitis Worse?
Yes. Although hydrocortisone can help many inflammatory skin conditions, topical corticosteroids may trigger or worsen perioral dermatitis in some patients.
This is one reason why identifying the correct type of rash is important.
The patient's mother had been using hydrocortisone cream to manage the facial irritation.
However, the rash continued to produce small bumps and flaking.
Topical corticosteroids may temporarily reduce redness while contributing to recurrent or persistent perioral dermatitis.
When steroid-associated perioral dermatitis is suspected, dermatologists often recommend avoiding unnecessary topical corticosteroid use on the affected facial skin.
Parents should not assume that a cream effective for eczema is also appropriate for a rash around the mouth.
For this patient, the dermatologist selected a nonsteroidal topical medication for the facial rash.
Can Certain Foods Cause Perioral Dermatitis in Children?
Parents sometimes notice that facial irritation appears worse after their child eats certain foods.
Acidic foods, including tomatoes and citrus fruits, can occasionally irritate the skin around the mouth, particularly when the skin barrier is already inflamed.
However, food contact irritation is not the same as a food allergy, and perioral dermatitis is not necessarily caused by dietary triggers.
In this case, the patient's mother had stopped offering tomato-based foods to see whether the rash would improve.
The clinical documentation did not establish a food allergy or confirm that tomatoes were responsible for the condition.
Other factors that may contribute to perioral dermatitis include topical corticosteroids, certain cosmetics or skin-care products, irritating toothpaste formulations, and environmental exposure.
Avoiding unnecessary dietary restrictions is important, particularly in young children.
How Is Perioral Dermatitis Diagnosed in Children?
Perioral dermatitis is generally diagnosed through a clinical examination.
A dermatologist evaluates the appearance, location, and distribution of the facial rash, along with the child's skin-care history.
During this patient's visit, the dermatology team examined the face and both forearms using dermoscopy.
The facial findings were most consistent with perioral dermatitis.
Other conditions that can resemble perioral dermatitis include:
Irritant contact dermatitis
Atopic dermatitis
Allergic contact dermatitis
Lip-licking dermatitis
Impetigo
Other inflammatory facial eruptions
Because treatment varies depending on the diagnosis, a dermatology evaluation may be helpful when a facial rash persists despite home care.
How Does Elidel 1% Cream Treat Perioral Dermatitis?
After discussing treatment options with the patient's mother, the dermatologist prescribed Elidel (pimecrolimus) 1% cream.
Elidel is a nonsteroidal topical calcineurin inhibitor that helps reduce inflammatory immune activity in the skin.
Although Elidel is FDA-approved for certain cases of atopic dermatitis in patients age 2 years and older, dermatologists may also prescribe it off-label for selected cases of perioral dermatitis.
Why Choose a Nonsteroidal Medication?
Unlike topical corticosteroids, Elidel does not cause steroid-related skin thinning.
It may be considered when a dermatologist wants to reduce inflammation while avoiding corticosteroid exposure on sensitive facial skin.
For this patient, the prescribed instructions were:
Elidel 1% cream: Apply to the affected rash twice daily.
The dermatologist also recommended continuing fragrance-free moisturizers.
Potential side effects include temporary burning, stinging, or irritation during application.
The family was counseled about the medication's safety information, including its boxed warning concerning reported malignancies with topical calcineurin inhibitors. A causal relationship has not been established.
Treatment should be used according to the prescribing dermatologist's instructions.
Why Does My Child Also Have Eczema on Her Arms?
In addition to the facial rash, the patient had experienced itchy, red patches on her arms for several months.
The examination identified findings consistent with atopic dermatitis, particularly involving the right and left antecubital areas—the inner elbow creases.
Atopic dermatitis is a chronic inflammatory skin condition associated with impaired skin barrier function and immune system activity.
Children with eczema often experience:
Red or inflamed patches
Dry, rough skin
Persistent itching
Recurrent flare-ups
Irritation in the elbow or knee creases
Skin thickening from repeated scratching
The inner elbows are common locations for childhood eczema.
Although eczema and perioral dermatitis can occur in the same child, they are distinct conditions.
What Triggers Eczema Flare-Ups in Young Children?
Atopic dermatitis often follows a recurring pattern, with periods of improvement followed by flare-ups.
Common aggravating factors include:
Fragranced soaps and body washes
Scented laundry detergents or fabric softeners
Dry skin
Weather changes
Excessive heat or sweating
Scratching
Skin infections
Certain irritating fabrics
The dermatologist discussed these potential triggers with the patient's mother and emphasized consistent skin care.
For children with eczema, maintaining a healthy skin barrier is an important part of long-term management.
How Does Fluocinolone 0.01% Body Oil Help Childhood Eczema?
For the eczema affecting the patient's arms, the dermatologist prescribed fluocinolone 0.01% topical body oil.
Fluocinolone is a topical corticosteroid that helps reduce inflammation, redness, and itching.
Unlike the nonsteroidal medication selected for the facial rash, this treatment was intended for eczema flare-ups on the body.
The Patient's Prescription
Fluocinolone 0.01% body oil: Apply to affected body areas twice daily for two weeks, then stop. May use as needed for future flare-ups according to the dermatologist's instructions.
The goal was to control active eczema inflammation while avoiding unnecessary continuous steroid exposure.
Parents should use topical corticosteroids only on the areas and for the duration prescribed.
Prolonged or inappropriate use can increase the risk of skin thinning and other adverse effects.
The family was also advised that additional treatment options, including biologic therapy, could be considered in the future if topical medications did not adequately control the child's eczema.
Biologic therapy was discussed as a possible future option and was not started during this visit.
Why Are Different Medications Used for the Face and Arms?
This patient's case highlights an important principle in pediatric dermatology: two rashes that appear similar may require different treatments.
Condition
Location
Prescribed treatment
Perioral dermatitis
Around the mouth
Elidel 1% cream twice daily
Atopic dermatitis
Inner elbows
Fluocinolone 0.01% body oil for flare-ups
Topical corticosteroids are commonly used to treat eczema, but they can worsen perioral dermatitis in some patients.
By distinguishing between the two conditions, the dermatologist was able to recommend a more targeted treatment plan.
What Is the Best Skin-Care Routine for a Child With Eczema and Perioral Dermatitis?
Daily skin care can help reduce irritation and support the skin barrier.
For this patient, the dermatologist recommended several practical measures.
Use Gentle, Fragrance-Free Cleansers
Choose mild cleansers and avoid harsh soaps, fragranced products, and unnecessary cosmetic treatments.
Moisturize Immediately After Bathing
Apply a fragrance-free moisturizer while the skin is still slightly damp.
For eczema-prone skin, moisturizers may be applied two to three times daily or as needed.
Keep Baths Lukewarm
Hot water can worsen dryness and irritation.
Short baths using lukewarm water are generally preferable.
Avoid Scented Laundry Products
Fragranced detergents and fabric softeners may irritate sensitive skin.
Protect the Skin From Environmental Irritation
Broad-spectrum sunscreen and gentle, noncomedogenic products may help reduce irritation from environmental exposure.
Keep Fingernails Short
Scratching can worsen eczema and increase the risk of skin infection.
Keeping fingernails trimmed can help minimize skin injury.
When Should Parents See a Dermatologist for a Child's Rash?
Some childhood rashes improve with gentle skin care, but others require prescription treatment.
Consider scheduling a pediatric dermatology evaluation if:
A rash around the mouth persists for several weeks.
Hydrocortisone does not improve the facial rash or appears to worsen it.
Eczema continues recurring on the arms or legs.
Itching interferes with sleep or daily activities.
The skin becomes cracked, painful, or increasingly inflamed.
Yellow, honey-colored crusting or other signs of infection develop.
Multiple rashes appear in different areas of the body.
A dermatologist can help determine whether the child has one skin condition or several overlapping disorders.
What Was the Treatment Plan for This 4-Year-Old Patient?
Following her evaluation at Village Dermatology, the patient received a treatment plan addressing both conditions.
Facial rash
Perioral dermatitis was favored, and Elidel 1% cream was prescribed twice daily.
Eczema on the arms
Fluocinolone 0.01% body oil was prescribed twice daily for two weeks, then as needed for flare-ups.
Supportive care
Fragrance-free moisturizers, gentle cleansing, lukewarm bathing, and avoidance of irritating products were recommended.
The patient's mother expressed understanding of the treatment recommendations.
At the time of the documented visit, the patient's response to the newly prescribed medications had not yet been established.
