Molluscum Contagiosum: Pearly Dome-Shaped Bumps With Central Dimples

If you notice small, smooth bumps that look pearly and seem to have a tiny dent in the center, molluscum contagiosum is one possible explanation. These bumps can look unusual at first, but they are a common viral skin condition seen in both children and adults. In many cases, they are more annoying than dangerous, though they can spread on the skin and sometimes to other people.

The tricky part is that molluscum can resemble other bumps, rashes, or minor growths. That is why a calm, accurate evaluation matters, especially if the bumps are multiplying, becoming irritated, or showing up in sensitive areas. A board-certified dermatologist can help confirm what is going on and talk through whether watchful waiting or treatment makes the most sense.

Quick answer

• Molluscum contagiosum is a viral skin infection that often causes small, firm, dome-shaped bumps with a central dimple.
• The bumps may spread through skin-to-skin contact or shared personal items.
• Many cases improve over time, but some people benefit from dermatologist-guided treatment.
• Try not to scratch, pick, or shave over the bumps, since that can spread them further.
• If you are unsure what the bumps are, it is worth getting checked.

What it is

Molluscum contagiosum is a superficial skin infection caused by a poxvirus. It usually appears as small, round, flesh-colored or pink-white bumps with a smooth surface and a tiny central indentation. Some bumps stay isolated, while others appear in clusters. They may show up on the trunk, arms, legs, underarms, groin, or other areas depending on age and exposure pattern.

Although the bumps are often painless, they can become red, itchy, or inflamed, especially if the surrounding skin is sensitive or if the area is rubbed. In children, the bumps are often seen on everyday exposed skin. In adults, location and spread pattern can vary, so it is smart not to self-diagnose based on appearance alone.

Common causes or triggers

• Direct skin-to-skin contact with someone who has molluscum contagiosum
• Sharing towels, clothing, razors, sports gear, or other personal items
• Scratching, picking, or shaving over existing bumps, which can spread them on the skin
• Close-contact activities, including some sports and other frequent skin contact
• A weakened skin barrier, which can be associated with easier spread in some people

What you can do at home

Conservative care starts with leaving the bumps alone as much as possible. Try not to squeeze, scratch, or pick them. Keep the skin clean, avoid sharing personal items, and consider covering visible bumps during close-contact activities if your clinician recommends it. If the surrounding skin feels dry or irritated, gentle skin-barrier care may help reduce rubbing and discomfort.

It is also a good idea to avoid shaving directly over affected areas, since that can spread the bumps. Over-the-counter products are not always appropriate for every age group or body area, so if you are considering self-treatment, check with a dermatologist first. This is especially important for bumps near the face, eyelids, or genital area.

Professional options

Many people notice that molluscum eventually clears, but treatment may be considered when bumps are spreading, bothersome, cosmetically frustrating, irritated, or located in sensitive areas. Common options include in-office treatments and carefully selected at-home prescription therapies. The right approach depends on age, skin sensitivity, number of bumps, and where they appear.

A dermatologist can evaluate whether observation is reasonable or whether active treatment may help. If there is any uncertainty about the diagnosis, an exam can also help distinguish molluscum from warts, folliculitis, milia, or other skin conditions that can look similar.

When to see a dermatologist

• You are not sure the bumps are molluscum contagiosum
• The bumps are rapidly increasing in number or spreading to new areas
• The skin becomes very red, painful, crusted, or seems secondarily infected
• The bumps are on the face, eyelids, groin, or another sensitive area
• The bumps are persistent, bothersome, or causing significant irritation
• You have a child with widespread bumps or skin that is also very inflamed

FAQ

Is molluscum contagiosum dangerous?

It is usually a harmless skin infection, but it can spread, become irritated, and sometimes be confused with other conditions. That is why diagnosis can be helpful when the appearance is unclear.

Can adults get molluscum contagiosum?

Yes. While it is common in children, adults can get it too. A dermatologist can help evaluate the pattern, location, and whether treatment may be useful.

Should I pop or scrape the bumps at home?

No. Picking or scraping can irritate the skin and may spread the bumps to nearby areas. It is safer to get guidance before trying to remove them.

Do I always need treatment?

Not always. Some cases are monitored, while others are treated because of spread, symptoms, location, or personal preference. Your clinician can help you decide what fits your situation.
