Dermatofibromas are firm, red-to-brown, small papules or nodules composed of fibroblastic tissue. They usually occur on the thighs or legs but can occur anywhere.

Dermatofibromas are common among adults, more so in women. Their cause is probably genetic. Lesions are usually 0.5 to 1 cm in diameter, firm, and may dimple inward with gentle pinching. Most lesions are asymptomatic, but some itch or ulcerate after minor trauma.
