Molluscum contagiosum appears as a larger number (usually around 20-40) of skin-coloured/brownish-pink, dome-shaped bumps on the skin. These bumps are approximately 2-3 mm in size, smooth, shiny, and have a small central dimple. They are often seen in clusters but can rarely occur individually. The diagnosis is based on the characteristic appearance. Molluscum contagiosum is more common in children than adults (9 out of 10 cases). The typical age range is 2-5 years. Molluscum bumps can appear anywhere on the body but are more common in areas with broken or irritated skin (such as eczema).
In adults, where the condition can be sexually transmitted, the skin lesions are most commonly found on the genitals, thighs, or lower abdomen. Molluscum contagiosum can cause mild itch but rarely significant discomfort. However, bacterial infections can develop in the molluscum bumps, leading to increased redness and discomfort. In rare cases, the skin lesions can result in local scarring.
Molluscum contagiosum is a superficial skin infection caused by the poxvirus, a relative of the smallpox virus. It is most commonly transmitted through direct skin contact. The time it takes for a newly infected person to develop bumps can vary from one week to six months. The bumps can also spread from one area of the body to another through the transfer of the virus (scratching, shaving, sharing towels, and clothing).
Molluscum contagiosum does not require treatment and will resolve on its own. Treatment is therefore not necessary or recommended. A crust forms on the bumps before they heal and eventually disappear. However, this process can take a long time, ranging from two months to two years. Children with underlying eczema may have molluscum contagiosum for a longer duration than those without skin conditions. To prevent the spread of the virus and the development of new bumps, it is important to keep nails short, cover affected skin areas, use separate towels, and practice good hygiene. Squeezing or scraping a molluscum bump may cause a white, cheesy substance to be released from the central dimple, potentially speeding up the healing process. However, this manipulation can be painful (often requiring local anesthesia) and increases the risk of further spread and bacterial infection. Therefore, it is not routinely recommended but may be considered for particularly bothersome or embarrassing molluscum bumps. Molluscum contagiosum can also be treated with cryotherapy by a dermatologist or with prescribed creams/solutions. Non-prescription options are also available.
