Molluscum Contagiosum Treatment St. Louis

Molluscum Contagiosum Treatment St. Louis

Molluscum contagiosum is a common viral skin infection caused by the molluscum contagiosum virus (MCV). It manifests as small, raised bumps on the skin, known as molluscum bumps or spots. This condition primarily affects children and individuals with weakened immune systems. MCV belongs to the poxvirus family and is highly contagious, spreading through direct contact with infected individuals or contaminated objects. The infection typically resolves on its own within 6 to 12 months, but it can persist for longer periods in some cases. While molluscum contagiosum is generally harmless, it can cause discomfort and lead to scarring if left untreated. At Mid-County Dermatology in St. Louis, MO, we recommend seeking medical attention for proper diagnosis and management of this skin infection.

Causes and Symptoms of Molluscum Contagiosum


Caused by direct contact with an infected person or contaminated objects

Molluscum contagiosum is caused by direct contact with an infected person or by touching contaminated objects. This contagious skin infection is primarily spread through skin-to-skin contact, such as during play, sports activities, or intimate contact. It can also be transmitted through sharing personal items like towels or clothing. So, if you come into contact with someone who has molluscum contagiosum or touch their belongings, there's a chance you could contract it too.

Bumps are usually painless but may become itchy or inflamed

One of the hallmark symptoms of molluscum contagiosum is the appearance of small bumps on the skin. These bumps are typically painless and have a characteristic dimple in the center. They may start off as tiny flesh-colored papules but can grow to be larger and more noticeable over time. While they are generally not painful, they can become itchy or inflamed due to scratching or irritation.

Lesions can appear anywhere on the body, including face, arms, and genitals

Molluscum contagiosum lesions can appear anywhere on the body. Common areas affected include the face, neck, arms, hands, and trunk. In children, lesions often occur in areas prone to friction from clothing or rubbing against other surfaces during play. In adults, these lesions may also affect the genital area due to sexual transmission.

The location of the lesions varies from person to person depending on how they came into contact with the virus. For example, if someone contracted molluscum contagiosum through sexual activity, they might have lesions around their genitals or inner thighs.

Lesions tend to cluster together in groups rather than being scattered randomly across the body. This clustering pattern makes them easier to identify and distinguish from other skin conditions. It's important to note that the number of lesions can vary greatly from just a few to several hundred.

Contagious Nature of Molluscum Contagiosum

Molluscum contagiosum is a highly contagious viral skin infection that can easily spread through close physical contact. The virus, known as the molluscum contagiosum virus, can be transmitted through direct skin-to-skin contact with an infected person. It's important to understand the contagious nature of this condition to take necessary precautions and prevent its spread.

Highly contagious and spreads easily through close physical contact

Molluscum contagiosum is highly contagious, meaning it can be easily passed from one person to another. Close physical contact, such as touching or rubbing against someone with the infection, increases the risk of transmission. This includes activities like hugging, wrestling, or playing contact sports.

Sharing personal items like towels or clothing can also transmit the virus

Apart from direct skin-to-skin contact, sharing personal items like towels, clothing, or bedding can also contribute to the spread of molluscum contagiosum. The virus can survive on surfaces for a short period of time and can be transferred when an uninfected person comes into contact with contaminated objects.

To avoid spreading the infection through shared items:

  • Avoid sharing towels or clothing with someone who has molluscum contagiosum.

  • Wash your hands thoroughly after coming into contact with any potentially contaminated surfaces.

Scratching or picking at the bumps can further spread the infection

Scratching or picking at the molluscum bumps on your own body can cause them to rupture and release infectious fluid. This fluid contains live virus particles that are capable of infecting nearby areas of your skin or being transmitted to others. It is crucial to avoid scratching or picking at these bumps to prevent further spread.

Here are some tips to prevent self-infection:

  • Keep your hands clean and avoid touching the affected areas unnecessarily.

  • If you accidentally touch a bump, wash your hands thoroughly with soap and water.

  • Cover the bumps with clothing or bandages to prevent direct contact.

Remember, molluscum contagiosum is most contagious when the bumps are present and visible. However, even after the bumps have resolved, it is still possible to transmit the virus until your body's immune system completely clears it.

Diagnosis Methods for Molluscum Contagiosum

To diagnose molluscum contagiosum, our St. Louis dermatology team primarily relies on visual examination of the characteristic skin lesions. The distinctive appearance of the bumps helps in identifying the condition. However, in some cases, additional diagnostic methods may be employed to confirm the presence of MCV (Molluscum Contagiosum Virus).

Visual Examination

Visual examination is often the first step in diagnosing molluscum contagiosum. Doctors carefully observe the skin lesions to look for specific characteristics that are typical of this viral infection. These include small, dome-shaped bumps with a central dimple or indentation, usually flesh-colored or pearly white in appearance.


In certain situations where there is doubt about the diagnosis or if other skin conditions need to be ruled out, a dermatologist may perform a biopsy. During a biopsy, a small sample of tissue is taken from one of the lesions and sent to a laboratory for analysis. This procedure helps to definitively confirm the presence of MCV.

Magnifying Lens Examination

Our BJC dermatologists may use a magnifying lens or dermatoscope to examine the molluscum contagiosum lesions more closely. This allows for a detailed inspection of individual bumps and can help differentiate them from other similar-looking skin conditions.

Diagnostic Tests

While visual examination and biopsy are usually sufficient for diagnosis, there are also diagnostic tests available that can detect the presence of MCV DNA in lesion samples. Polymerase chain reaction (PCR) tests and viral culture techniques can provide further confirmation.

It's important to note that self-diagnosis based solely on visual appearance can lead to misdiagnosis since there are other skin conditions with similar symptoms. Therefore, it is always recommended to consult with a healthcare professional for an accurate diagnosis.

Diagnosing molluscum contagiosum involves careful observation and sometimes additional tests such as biopsies or magnifying lens examinations. These methods help to ensure an accurate diagnosis and differentiate molluscum contagiosum from other skin conditions that may have similar appearances.

Managing and Preventing the Spread of Molluscum Contagiosum

To effectively manage and prevent the spread of molluscum contagiosum, there are several key steps individuals can take. By following these guidelines, you can minimize the risk of transmission and promote faster healing.

1. Keep affected areas clean and dry to prevent secondary infections

One important aspect of managing molluscum contagiosum is maintaining good hygiene. Keeping the affected areas clean and dry can help prevent secondary infections from occurring. Gently washing the affected areas with mild soap and water can help remove any dirt or debris that may contribute to infection. After washing, be sure to pat the area dry with a clean towel.

2. Avoid sharing personal items such as towels or razors

Molluscum contagiosum is highly contagious and can easily spread through direct contact with infected individuals or contaminated objects. To reduce the risk of transmission, it's crucial to avoid sharing personal items such as towels, razors, or clothing with others. These items can harbor the virus and facilitate its spread.

3. Practice good hand hygiene to minimize transmission

Proper hand hygiene is essential in preventing the spread of molluscum contagiosum. Regularly washing your hands with soap and water for at least 20 seconds helps eliminate any potential viruses on your hands. Using hand sanitizers containing at least 60% alcohol when soap and water are not readily available can also be effective in reducing transmission.

4. Consider physical removal options for faster healing

In some cases, physical removal methods may be recommended by dermatologists to expedite healing. One common method is curettage, which involves scraping off the lesions using a small instrument called a curette. Another option is topical medications that contain ingredients like cantharidin, which causes blistering around the lesions leading to their removal.

5. Take extra precautions for immunocompromised persons

Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, may experience more severe and persistent cases of molluscum contagiosum. These individuals must work closely with their dermatologist to develop a comprehensive management plan that addresses their specific needs.

6. Minimize contact in high-risk environments

Certain settings, such as schools or healthcare facilities, can pose an increased risk of spreading molluscum contagiosum due to close contact among individuals. In these environments, it's important to take extra precautions to minimize transmission. This may include avoiding direct skin-to-skin contact, practicing good hygiene, and promptly notifying relevant authorities about any suspected cases.

7. Educate others about the infection

Raising awareness about molluscum contagiosum can help prevent its spread within communities. By educating others about the infection and its transmission methods, you can contribute to a safer environment for everyone. Encourage open communication and provide accurate information to dispel misconceptions surrounding the condition.

Treatment Options for Molluscum Contagiosum

Most cases of molluscum contagiosum resolve on their own within 6-12 months without any treatment. However, in some cases, treatment may be necessary to alleviate symptoms and promote faster healing. Dermatologists offer various treatment options depending on the severity and location of the lesions.


Cryotherapy is a common treatment option for molluscum contagiosum. It involves freezing off individual lesions with liquid nitrogen. The extreme cold temperature destroys the virus and causes the lesions to fall off within a few weeks.


  • Effective in removing individual lesions

  • Quick procedure that can be done in a dermatologist's office

  • Minimal discomfort during the procedure


  • May cause temporary redness, blistering, or scarring at the treated site

  • Multiple sessions may be required for complete clearance

  • Not suitable for treating large clusters of lesions

Cantharidin/Cantherone Solution

Cantharidin/Cantherone solution is another topical treatment option used by dermatologists to treat larger clusters of molluscum contagiosum. This solution contains an active ingredient that helps cause the molluscum lesions to blister off.


  • Can be applied directly to the affected area

  • Effective in treating larger clusters of lesions

  • Generally well-tolerated with minimal side effects


  • Requires consistent application over several weeks

  • May cause skin irritation or redness at the application site

  • Not recommended for use on children under 2 years old or during pregnancy

Other Treatment Options

In addition to cryotherapy and cantharidin solutions, dermatologists may consider other treatment options based on individual cases:

  1. Curettage: This involves scraping off the molluscum bumps using a small instrument called a curette.

  2. Laser therapy: Involves using a laser to destroy the lesions.

  3. Vitamin A creams: A topical medication that stimulates the immune system to fight against the virus.

It's important to consult with a dermatologist for proper diagnosis and guidance on the most suitable treatment option for molluscum contagiosum. They can assess the severity of the condition and recommend an appropriate course of action based on individual circumstances.
