Molluscum Contagiosum

Excerpt

Molluscum contagiosum (MC) is a common, benign epidermal eruption caused by a virus that affects both children and adults, including healthy and immunocompromised individuals. Characteristic lesions are skin-colored, dome-shaped papules that may resemble other dermatologic conditions, making accurate diagnosis challenging at times. Although MC is typically harmless and self-limited, its contagious nature, cosmetic impact, and risk of complications in specific populations warrant clinical attention and patient education.

MC is common in childhood, and the virus may also be sexually transmitted or linked to participation in contact sports in teenagers and adults. Additionally, it is associated with immunodeficiency, infecting individuals with inherited disorders, HIV infection, or those on immunosuppressive therapy. Transmission occurs directly through skin-to-skin contact or indirectly via fomites from contaminated objects such as towels, clothing, gym equipment, toys, swimming pool surfaces, and sports gear. It can also spread through autoinoculation, where affected individuals transfer the virus to nearby or distant skin areas by scratching or touching existing lesions. The incubation period typically ranges from 2 to 6 weeks. The duration of lesions varies, but in most cases they are self-limited and resolve within a year. See Image. Molluscum Contagiosum.
