Dermatofibroma

What it is

A dermatofibroma is a small, firm growth made of fibrous tissue that is found in the deeper layer of your skin. It is not a breast condition, but a skin condition that can happen to be located on the breast. These bumps are harmless.

How common it is

Dermatofibromas are common skin bumps, especially in adults. It is not unusual to find one on the skin of the breast.

What you may notice

You might notice a small, firm bump on your skin that feels like a hard pea under the surface. It can be pink, red, or brown, and it might dimple or pucker inward if you pinch the skin around it.

What can contribute

The exact cause is not always known, but they can sometimes form after a minor skin injury, like an insect bite or a scratch from shaving.

How it is usually checked

Your provider can usually identify a dermatofibroma just by looking at and feeling it. Sometimes, they may use a special magnifying light to see it more clearly. If there is any question about the diagnosis, a small skin sample, called a biopsy, may be taken to be sure.

Does this change my long-term risk?

Having a dermatofibroma is not related to your breast health. It does not change your long-term breast health risk.

Comfort and everyday care

• Most dermatofibromas do not need any treatment and can be left alone.
• If the spot gets irritated by clothing or shaving, you can try covering it with a small bandage.
• Try to avoid scratching or picking at the bump, as this can cause irritation or bleeding.
