Pearly bumps, central dimple
Molluscum contagiosum is a viral skin infection caused by the molluscum contagiosum virus (a poxvirus). It produces small (2-5mm), firm, dome-shaped, flesh-colored or pearly bumps with a characteristic central dimple (umbilication).
It is extremely common in children aged 1-10 and spreads through direct skin contact, shared objects, or water (swimming pools). In adults, it can be sexually transmitted when affecting the genital area.
The bumps are usually painless and can appear anywhere on the body. In children, they are most common on the trunk, arms, and face. They can occur singly or in clusters of dozens.
In healthy children, molluscum typically self-resolves within 6-18 months as the immune system clears the virus. Treatment is optional and includes cryotherapy, curettage, topical agents (cantharidin, tretinoin), and observation. In immunosuppressed patients, lesions may be widespread and persistent, requiring more aggressive treatment.

Risk factors
- Childhood (ages 1-10)
- Direct skin contact with infected individuals
- Swimming pools and shared bathing
- Eczema (disrupted skin barrier facilitates spread)
- Immunosuppression (HIV - lesions can be widespread)

Should I treat molluscum or wait?
In healthy children, observation is often the best approach - the virus clears on its own in 6-18 months. Treatment may be considered to reduce spread, prevent autoinoculation, or for cosmetic concerns. Discuss options with your pediatrician.
Can my child go to school with molluscum?
Yes. Children with molluscum do not need to be excluded from school or activities. Covering visible lesions with clothing or bandages reduces transmission risk.
