dermatofibroma

 [der″mah-to-fi-bro´mah]
a fibrous tumorlike nodule of the skin, usually on the extremities and especially the legs. Its etiology is not known, but it is most likely a neoplastic disorder. Although it is benign, itching and pain can be a source of severe discomfort.

der·ma·to·fi·bro·ma

(der'mă'tō-fī-brō'mă),
A slowly growing benign skin nodule consisting of poorly demarcated cellular fibrous tissue enclosing collapsed capillaries, with scattered hemosiderin-pigmented and lipid macrophages. The following terms are considered by some to be synonymous with, and by others to be varieties of, dermatofibroma: sclerosing hemangioma (2), fibrous histiocytoma, nodular subepidermal fibrosis.

benign fibrous histiocytoma

A benign tumour composed of primitive mesenchymal cells (macrophages or histiocytes) seen in the skin and soft tissues of the legs of young to middle-aged patients, more commonly women, usually in relation to skeletal muscle.
 
Management
Excision.
