SynopsisDermatofibromas, or histiocytomas, are common, benign skin neoplasms composed of collagen, macrophages (histiocytes), capillaries, and fibroblasts. The etiology and pathogenesis are unknown, though some may arise at sites of trauma or insect bites. They are firm, skin-colored or slightly pigmented papules or nodules. They may be tender or pruritic, and they often persist for life. They are most common on the legs of women and usually appear in young adulthood. They may heal as depressed scars after several years.
Dermatofibromas are often solitary, though any individual may have more than one.
