Dermatofibroma
A common type of benign skin tumor that is small, slow-growing, typically firm, red-to-brown and most often on the legs. Also called a fibrous histiocytoma. They can grow up to about 1 cm (less than a half inch) in diameter. A dermatofibroma consists of a proliferation of scar-like tissue within the deeper layers of the skin (dermis). The cause of dermatofibromas is unknown. They are usually single but sometimes may be multiple. Simple excision is curative.

der·ma·to·fi·bro·ma (dur″mə-to-fi-broґmə) [dermato- + fibroma] a benign, circumscribed, red to brown nodule in the dermis, composed of macrophages that may differentiate to resemble fibroblasts, usually found on the lower legs of women, often after minor trauma. It is a form of benign fibrous histiocytoma, and the two terms are sometimes used synonymously. NOTE: Terminology is variable; several other lesions may be synonymous with or variants of dermatofibroma and benign fibrous histiocytoma, including nodular subepidermal fibrosis and sclerosing hemangioma.
