BACKGROUND

Dermatofibromas (DFs), also called benign fibrous histiocytomas, are benign connective tissue neoplasms that have a predilection for the lower extremities. DFs are extremely common and have multiple histologic and clinical variants. They occur more commonly in females than in males at a 2:1 ratio and are slow growing, and in 20% of cases development of a DF correlates to a site of mild trauma such as an injection or insect bite.


PRESENTATION

Patients present with a complaint of a long-standing dark pimple, bump, or mark on the extremities that does not fade but can be pruritic or tender.
