Early dermatofibroma. Pinkish-red nodule on arm of 2-year-old child.

Late dermatofibroma. Brownish-red nodule on leg of teenager.

CLINICAL FEATURES

Small, firm nodules that are red at first, and later brown, are seen in dermatofibromas. Lateral pressure on the dermatofibroma will produce dimpling of the overlying surface.

They are frequently on the legs or trunk but may appear anywhere on skin. They are more common in the older child or teenager. Often, multiple lesions are present.

A prior history of trauma can sometimes be obtained. They may grow up to 1 to 2 cm. Once present, dermatofibromas persist. Rarely, they are painful.

TREATMENT

Usually no intervention is required. If painful, then surgical excision is recommended.
