Molluscum Contagiosum: Symptoms, Size, Duration, and Treatment - Dermatology

More Info

---

Molluscum contagiosum is a common viral skin infection caused by the molluscum contagiosum virus (MCV), which is part of the poxvirus family. It primarily affects the skin and is characterized by small, raised, flesh-colored or pearly-white bumps, which can appear anywhere on the body but are most commonly found on the face, neck, armpits, arms, and genital area.

Symptoms
The primary symptom of molluscum contagiosum is the appearance of these small, dome-shaped lesions. They typically have a central dimple or pit and can range in size from 2 to 5 millimeters, although they can sometimes grow larger. The lesions are usually painless and may be itchy, but they do not typically cause significant discomfort.

Size and Duration
The size of the lesions can vary, but they are generally small, as mentioned above. Molluscum contagiosum lesions can persist for several months to a few years. In many cases, the lesions may resolve on their own without treatment, but this can take anywhere from 6 months to 4 years. During this time, new lesions may appear, and the total number of lesions can increase, especially if the virus spreads to other areas of the skin.


Transmission
Molluscum contagiosum is considered a skin disease rather than a sexually transmitted disease, although it can be transmitted through direct skin-to-skin contact, including sexual contact. It can also spread through contaminated objects, such as towels, clothing, or gym equipment. Therefore, if you have molluscum contagiosum, it is advisable to wash your clothes separately from those of family members to minimize the risk of transmission.


Treatment
While many cases of molluscum contagiosum resolve without treatment, there are several options available if the lesions are bothersome or persistent. Treatment methods include:
1. Cryotherapy: Freezing the lesions with liquid nitrogen.

2. Topical treatments: Prescription creams or ointments, such as imiquimod or cantharidin, can be applied to the lesions to help them resolve.

3. Curettage: A minor surgical procedure where the lesions are scraped off.

4. Laser therapy: In some cases, laser treatment may be used to remove the lesions.

It is essential to consult a healthcare provider for an accurate diagnosis and appropriate treatment plan, especially if you are experiencing discomfort or if the lesions are spreading.


Conclusion
In summary, molluscum contagiosum is a viral skin infection characterized by small, painless lesions that can persist for an extended period. While it is not classified as a sexually transmitted disease, it can be transmitted through direct contact. If you suspect you have this condition, it is advisable to seek medical advice for proper diagnosis and treatment options. Additionally, practicing good hygiene and separating your laundry can help prevent the spread of the virus to others.
