A dermatofibroma is a common benign fibrous skin lesion. It is also known as fibrous histiocytoma. A dermatofibroma is a round, brownish to purple growth commonly found on the legs and arms. Dermatofibromas contain scar tissue and feel like hard lumps in the skin. A dermatofibroma consists of a proliferation of scar-like tissue within the deeper layers of the skin (dermis). A dermatofibroma is also sometimes called a fibrous histiocytoma. It is due to a non-cancerous growth of dermal dendritic histiocyte cells. Treatment of dermatofibromas should be considered when they get in the way of shaving or become irritated by clothing. In these cases surgical shaving of the top, punching out the center and maybe freezing with liquid nitrogen can be done. These treatments only destroy the upper part of the growth, and after a few years it may again become noticeable. If this happens, the treatment could be repeated again if desired.
