Dermatofibromas frequently occur on the leg, usually as a single firm, raised pink to brown bump. Dermatofibromas are usually very firm to hard to the touch.  They are most frequent on the arms and legs but can occur anywhere. Dermatofibromas are benign, usually very firm to hard skin lesions that do not resolve over time. This image displays a dome-shaped, firm, slightly pink dermatofibroma. Dermatofibromas can be raised or sunken. Dermatofibromas are firm, smooth, and often are deeper in color than the surrounding skin.

Signs and Symptoms
Dermatofibromas are most often found on the arms and legs of women. They are small brown or reddish-brown mobile nodules, and they feel quite firm. They may be tender to touch. Many lesions demonstrate a "dimple sign," where the central portion puckers as the lesion is compressed on the sides. They generally do not change in size.
