Dermatofibroma: A Common Skin Lump That’s Usually Harmless

Keywords: mole removal in Melbourne, sun spot removal in Melbourne

If you’ve ever noticed a small, firm bump on your skin—often on your legs or arms—you may have discovered a dermatofibroma. These harmless skin nodules are one of the most common findings during routine skin checks in Melbourne. Though they can feel unusual or look like a mole, dermatofibromas are benign and generally nothing to worry about.

That said, it’s always smart to have any new or changing skin lesion checked professionally.

What Is a Dermatofibroma?

A dermatofibroma is a small, non-cancerous growth that forms in the dermis (the thick layer of skin beneath the surface). It’s usually caused by a minor skin injury, like a mosquito bite, ingrown hair or a scratch, which triggers an overgrowth of fibrous tissue.

Key features include:

  • Firm, round or oval lump

  • Size: usually 5–10 mm

  • Often brown, red, or skin-coloured

  • Feels like a small pea under the skin

  • Usually found on the lower legs, arms or shoulders

  • Doesn’t go away but stays stable over time

A classic sign of a dermatofibroma is the dimple sign: when you pinch the lesion, it dimples inward.

Is It Dangerous?

No. Dermatofibromas are completely benign and don’t turn into skin cancer. However, because they may resemble other skin conditions, such as moles or even basal cell carcinoma in rare cases, it’s important to have them professionally assessed—especially if:

  • The lesion changes in size or colour

  • It starts bleeding or itching

  • You’re unsure if it’s new or has been there for a long time

In most cases, a trained GP or dermatologist can diagnose it through visual inspection and by feeling the lump. If there’s any doubt, a biopsy may be performed to confirm the diagnosis.

Can It Be Removed?

Yes—but only if it’s causing problems. Dermatofibromas do not need treatment unless they:

  • Are painful

  • Interfere with shaving or clothing

  • Are cosmetically bothersome

Clinics offering mole removal in Melbourne or sun spot removal in Melbourne often provide removal services for dermatofibromas as well.

Removal Options:

  • Surgical Excision: The only method that fully removes a dermatofibroma. It leaves a scar, so it’s usually done only if necessary.

  • Shave Excision: Flattens the bump but may not remove it completely.

  • Cryotherapy: Less effective but may reduce size in some cases.

When to Get It Checked

You should consider visiting a skin cancer clinic in Melbourne if:

  • You have a new skin bump or lesion

  • An existing spot has changed in shape, colour or feel

  • You’re unsure if it’s a dermatofibroma or something more serious

Melbourne skin clinics routinely assess and monitor benign growths, offering reassurance and, if needed, safe and simple removal options.

Final Thoughts

A dermatofibroma is a harmless skin growth that often causes unnecessary worry. Though it doesn’t require treatment, it should be properly diagnosed—especially if you’re unsure. And for those who’d like it removed for comfort or cosmetic reasons, mole removal services in Melbourne are available to help.

If in doubt, book a skin check. It’s the best way to protect your health and your peace of mind.
