Molluscum vs Warts: Understanding the Difference

Molluscum contagiosum is a skin condition caused by a virus in the poxvirus family. It often shows up as small, smooth, firm, dome-shaped bumps, and some have a small dimple in the center. Warts, by contrast, are caused by human papillomavirus (HPV) and often feel rougher or more textured, though this varies.

Both can spread through skin-to-skin contact or shared items like towels, and both can appear on different parts of the body. Because they can look similar, especially in early stages or on certain skin types, guessing by appearance alone is unreliable. A clinician can often distinguish them by looking closely, and sometimes further evaluation is needed.

Neither should be treated as a do-it-yourself identification project. Any spot that is changing, bleeding, itching, irregular in shape or color, or not healing should be checked by a dermatologist for skin cancer, and should not be self-treated. The ABCDEs of melanoma (asymmetry, border, color, diameter, evolving) are only a general guide, never a way to diagnose yourself.

Bumps in the genital area deserve a calm, private visit with a clinician. They may be molluscum, warts, or something else entirely, and a provider can sort that out without judgment.

Molluscum has traditionally been approached in a few ways, including watchful waiting, since in many people it may eventually go away on its own over time. How long that takes varies a great deal from person to person.

When people and clinicians choose to act, in-office options have included cryotherapy (freezing), scraping, or a blistering agent such as cantharidin applied by a clinician. Warts have traditionally been approached with over-the-counter salicylic acid products, freezing, or other in-office methods. The current FDA status of specific prescription products, including cantharidin formulations, is something to confirm with your provider.

Results vary, and both molluscum and warts can return, so no approach should be considered a cure or a guarantee. People with diabetes, poor circulation, neuropathy, or a weakened immune system should ask a provider before treating anything at home, especially on the feet. Never cut, burn, or dig out a growth, and avoid over-the-counter wart products on the face or genitals.

The right provider, such as a dermatologist, podiatrist, primary care clinician, or sexual-health provider, may help by examining the bumps and discussing what they appear to be. A visit generally involves looking at the skin, asking about when the bumps appeared, and talking through whether to wait or consider options.

Only a licensed clinician decides what is appropriate for you after an evaluation. They may also talk about how to reduce spreading to others, which can be a common worry for parents and partners.

Helpful questions to ask include: What do you think these bumps are, and how sure are you? Is waiting a reasonable option? What are the pros and cons of in-office approaches? Could they come back? If the bumps are genital, ask about partner conversations and whether HPV vaccination is something to discuss.
