What is it? A dermatofibroma is a very common, firm, button like growth in the skin. Its
color is usually darker than the surrounding skin. Typically it occurs on the arms and legs. Dermatofibromas may be tender to touch or pressure.
What causes it? The cause is unknown but some Dermatologists believe it is a chronic reaction to a previous insect bite. Dermatofibromas appear gradually over several months, and may persist for years. All ages and both sexes are susceptible to dermatofibroma.
Is it dangerous? Dermatofibromas are not dangerous.
Can it be cured? Surgical removal is not usually recommended due to the scar being more cosmetically unacceptable than the dermatofibroma. Surgical removal or biopsy may be needed if the dermatofibroma is repeatedly traumatized, has an uncertain diagnosis or is cosmetically unacceptable.
Will it spread? It is common to have more than one dermatofibroma, but they do not spread to "other areas".
Is it contagious? Dermatofibromas are not contagious and you cannot "catch it" from anyone.
