Introduction 

Skin conditions can be uncomfortable, persistent, and sometimes confusing. Two skin conditions that often raise concerns are molluscum contagiosum and eczema. Despite the fact that both conditions affect the skin, they have very distinct causes, symptoms, and treatments. Molluscum contagiosum is a viral infection that causes the presentation of small dimpled spots to appear on the skin and is harmless.¹ Eczema is a common skin condition that usually causes skin patches to feel itchy or sore.² This article aims to demystify these conditions and shed light on their differences, causes, symptoms, prevention and treatment. 

What is molluscum contagiosum? 

• Molluscum contagiosum (MC), often known as water warts, is a viral infection that causes little pink lesions that are elevated and have a dimple in the middle  
• They can appear singly or in clusters, and they can get irritating or painful 
• Any part of the skin can be impacted, however, the most frequently affected areas are the face, genital area, arms, legs, stomach, and neck³
• It mostly affects children between 1 and 10, but people of any age can become affected¹

Causes and transmission

• The molluscum contagiosum virus (MCV), is a member of the poxvirus family and is the source of molluscum contagiosum, a skin infection  
• It can be transmitted by direct skin-to-skin contact, contact with contaminated things (such as toys or towels), and in certain cases, sexual contact between adults ¹
• It is highly contagious but is usually harmless, and hardly ever requires medical attention^1,2

Symptoms

Molluscum contagiosum causes the appearance of small, firm, raised bumps on the skin. These bumps are called Mollusca and are flesh-coloured or pink, dome-shaped, and between 2-5mm in diameter. The most common places for children to get molluscum lesions are the face, arms, legs, torso, and armpits 

Molluscum bumps in the genital area are common in adults and are thought to be a sexually transmitted infection. Although these bumps usually do not hurt, they occasionally itch or are inflamed. Scratching or picking them could result in scarring, an additional bacterial infection, and the viral infection that causes molluscum contagiosum to spread^1,2

Diagnosis

• Diagnosis is straightforward. It is based on the appearance of the bumps  
• A healthcare provider can diagnose MC through a physical examination 
• In rarer cases, skin scraping or a biopsy can be done^1,2

Treatment 

MC usually resolves within 6-12 months without medications. In rare cases, MC can persist for years. Some treatments include:³

• Cryotherapy: Freezing the bumps with liquid nitrogen 
• Curettage: Physically removing the bumps with a small tool 
• Topical treatments: Applying creams or ointments that contain ingredients like salicylic acid, tretinoin, or cantharidin to help remove the lesions 
• Laser therapy: Used to remove the bumps  

Prevention & management

There are a few ways in which the spread of MC can be prevented:¹

• Avoiding direct skin-to-skin contact with someone who is infected with Molloscum Contagiosum
• Refrain from sharing personal belongings like towels, clothing, or toys
• Practising good personal hygiene
• Covering the bumps with clothing or bandages to reduce the risk of spreading the virus 

What is eczema?

Atopic dermatitis, another name for eczema, is a chronic inflammatory skin disorder that causes red, swollen, and itchy skin eczema is not brought on by a virus or bacteria, compared to Molluscum Contagiosum. It is the outcome of a confluence of immune system, environmental, and genetic variables. There are several types of eczema, including:⁴

• Atopic dermatitis: The most common form, mainly seen in children but can continue into adulthood 
• Contact dermatitis: Triggered by direct contact or allergens 
• Dyshidrotic eczema (Pompholyx): Causes small blisters on hands and feet 
• Nummular eczema (Discoid eczema): Characterised by circular, coin-shaped spots on the skin 
• Seborrheic dermatitis: Often affects the scalp and face, causing flaky, greasy scales 
• Stasis dermatitis(Varicose eczema): Occurs in the lower legs due to poor circulation 

Symptoms

Eczema symptoms can vary widely but typically include:

• Red, inflamed skin 
• Intense itching 
• Dry, scaly, or thickened skin 
• Small, raised bumps that may leak fluid when scratched 
• Crusting or oozing in severe cases 

The location of the rash can differ depending on the type of eczema and the age of the person affected. For example, in infants, eczema often appears on the face and scalp, while in older children and adults, it is more common on the hands, neck, inner elbows, and backs of the knees.

Diagnosis

Diagnosing eczema is usually done based on the appearance of the skin and through medical history. Healthcare providers may ask about family history, as eczema often runs in families and may also inquire about potential triggers. In some cases, patch testing or skin biopsies may be performed to rule out other conditions.

Treatment 

While there is no cure for eczema, the condition can be managed with a combination of treatments and lifestyle changes to reduce symptoms and prevent flare-ups

Some treatment options include:⁴

• Moisturisers: Keep skin well-hydrated and regularly use moisturising lotions/ creams
• Topical corticosteroids: Anti-inflammatory creams or ointments help which will reduce redness and itching
• Topical calcineurin inhibitors: Non-steroidal creams that are used to reduce inflammation and immune response
• Oral medications: In severe cases, oral corticosteroids or immunosuppressants may be prescribed
• Antibiotics: If a secondary bacterial infection develops, antibiotics may be necessary
• Antihistamines: These can help control itching, especially if it interferes with sleep
• Phototherapy: Exposure to ultraviolet light under medical supervision can help reduce symptoms

Prevention & management

Managing eczema involves identifying and avoiding triggers, such as:⁵

• Irritants: Harsh soaps, detergents, and fabrics like wool 
• Allergens: Pet dander, pollen, dust mites, and certain foods
• Environmental Factors: Extreme temperatures, humidity levels, and stress

Other management strategies include:

• Taking lukewarm baths and using gentle, fragrance-free cleansers
• Applying moisturisers immediately after bathing or showering to lock in moisture
• Wearing soft, breathable clothing
• Utilising a humidifier in arid environments to sustain skin moisture

Comparing molluscum contagiosum and eczema

Differences

• Cause: Molluscum contagiosum is caused by a virus, while eczema is a result of genetic, environmental, and immune factors
• Symptoms: Molluscum presents as small, firm, raised bumps, whereas eczema is characterised by red, inflamed, and itchy skin.
• Transmission: Molluscum is contagious and spreads through direct contact, whereas eczema is not contagious
• Duration: Molluscum usually resolves on its own within months to a couple of years. Eczema is a chronic condition that can persist for a lifetime with periodic flare-ups

Similarities

• Skin-related: Both conditions affect the skin and can cause significant discomfort
• Appearance: Both can cause visible skin changes, which may be a source of concern for patients
• Management: Both conditions can benefit from topical treatments to alleviate symptoms

Living with molluscum contagiosum & eczema

Emotional and psychological impact

• Having noticeable skin disorders such as eczema and MC can have a negative impact on one’s self-esteem and confidence 
• It is typical to have feelings of humiliation, annoyance, and self-consciousness 
• To deal with these difficulties, it is critical to look for assistance from medical professionals, mental health specialists, and support organisations. This will make you feel less alone and connect with others going through a similar experience

Tips for parents and individuals dealing with eczema and molluscum contagiosum

• Educate yourself about the conditions to better manage and prevent flare-ups or spreading
• Maintain a regular skincare routine to keep the child’s skin healthy
• Encourage good hygiene practices to prevent the spread of molluscum contagiosum
• Foster a supportive and understanding environment to help the child cope emotionally

Summary

Eczema and molluscum contagiosum are two different skin disorders that have different causes, signs, and therapies. Effective management of these distinctions requires an understanding of them. Eczema is a chronic ailment that needs constant care, but molluscum contagiosum is a viral infection that frequently goes away on its own. Both illnesses have the potential to greatly affect a person's quality of life, but with the right support and care, people can live long healthy lives.
