What is dermatofibroma?

A dermatofibroma is a common, benign skin lesion that can develop over time. This small bump can appear almost anywhere on the body, but usually makes its home on the leg. Also known as benign fibrous histiocytoma, this slow-growing lesion is more commonly seen in women.

They are not secluded to a single area of the body, and it is possible to have multiple of these small bumps on the skin. Dermatofibromas can be a dark tan color, but can also be more red or pink. These small bumps are filled with fibrous tissues, and tend to stick around for many years.

How are dermatofibromas treated?

Dermatofibromas aren't dangerous and are usually fine to be left alone on the skin, but there are a number of ways to remove the spots if desired, including:

Surgical excision, a complete removal that will leave a mild scar
Cryotherapy, which uses liquid nitrogen to freeze off the growth
Laser treatment, which uses targeted light therapy to flatten and lighten the growth

Talk to a dermatologist at one of our convenient locations across Texas (Houston, Pflugerville, Austin, Bee Cave, Dripping Springs) or Louisiana (Metairie, Old Metairie, Uptown New Orleans, Baton Rouge) to understand which treatment may be best for you.

Dermatofibromas often arise after trauma to the skin, such as a bug bite or nicking the skin while shaving.

One way that can help confirm the diagnosis of a dermatofibroma is to look for the ‘Dimple Sign.’ Many of these lesions will form a dimple or depression inwards if squeezed on the sides. Your dermatologist may also perform a biopsy if the diagnosis is uncertain, or if they cannot definitively tell you that your lesion is a dermatofibroma after performing a skin exam.

No, dermatofibromas are not typically dangerous. However, there are some situations where they can be associated with underlying health issues. Typically, multiple dermatofibroma lesions that arise suddenly are seen in these situations. If you have multiple skin lesions that have come on suddenly, you should discuss this with your physician.
