Dermatofibromas

Dermatofibromas are common, benign growths that usually appear on the skin’s surface. These fibrous nodules are typically brown or tan and are often mistaken for other types of skin conditions. While generally harmless, dermatofibromas can cause discomfort or self-consciousness. At Skinsol Dermatology, we offer treatment options to remove or manage these growths effectively.

Causes and Risk Factors

Dermatofibromas are usually caused by an overgrowth of fibrous tissue in response to minor skin injuries, such as insect bites, cuts, or trauma. The risk factors include:

  • Trauma: Physical injury to the skin can lead to the formation of dermatofibromas.

  • Genetics: Some individuals may be genetically predisposed to develop dermatofibromas.

  • Age: Dermatofibromas most commonly appear in adults, typically between the ages of 20 and 40.

  • Gender: Women are more likely than men to develop dermatofibromas.

While dermatofibromas are benign, if you notice changes in size, color, or texture, it’s important to have them evaluated by a dermatologist.

Diagnosis

Our provider, Victoria McKay, PA-C, will perform a thorough evaluation to diagnose dermatofibromas, which typically involves:

  • Visual inspection: The provider examines the lesion to determine its characteristics.

  • Dermatoscopy: A specialized tool that provides a magnified view of the skin to assess the growth’s features.

  • Skin biopsy: In rare cases, a biopsy may be performed if the growth appears atypical or if there is concern about other conditions.

Early diagnosis is important to rule out other potential skin conditions.

Treatment Options

While dermatofibromas are generally harmless and don’t require treatment unless they cause pain or cosmetic concerns, we offer several removal options, including:

  • Surgical excision: A minor surgical procedure to remove the dermatofibroma entirely.

  • Shave removal: A procedure in which the growth is shaved off at the surface of the skin.

  • Cryotherapy: Freezing the growth with liquid nitrogen to remove it.

After removal, the lesion may leave a scar, but treatment options are available to minimize scarring. Your provider will discuss the best approach based on the location and size of the dermatofibroma.

FAQs

  • No, dermatofibromas are benign growths and are not cancerous. However, they can sometimes be mistaken for other skin conditions, so it’s important to have them evaluated by a dermatologist.

  • Dermatofibromas typically do not go away on their own. They may remain the same size or slowly shrink over time, but treatment may be required for removal if they become bothersome.

  • There is a potential for scarring after removal, but our providers take measures to minimize scarring and ensure the best cosmetic result.
