Dermatofibroma (fibrous histiocytoma)
What is a dermatofibroma?
A dermatofibroma is a benign growth of the skin. It is firm, can be skin-colored, reddish or brown, and can be raised or depressed. They are most commonly found on the legs in adults.
What causes dermatofibroma?
Some individuals will report trauma to the area from shaving, or an insect bite prior to the dermatofibroma’s appearance. However, sometimes dermatofibromas appear without any report of preceding trauma.
How are dermatofibromas treated?
Dermatofibromas are not harmful and many soften over time. Thus, they do not need to be treated. For those desiring cosmetic treatment, the dermatofibroma could be cut out. However, doing this would leave a scar, often quite similar to the dermatofibroma. Injections of corticosteroid have also had mixed results.
When should I contact my physician?
Other skin growths can mimic dermatofibromas. If you are unsure about the nature of your skin growth of if your dermatofibroma continues to change, see your doctor to have your skin evaluated.
