Nodular 'fasciitis' presenting as a cutaneous polyp.

A polypoid cutaneous variant of 'nodular fasciitis' presenting on the upper arm of an 8-year-old girl is described. Nodular fasciitis is a reactive myofibroblastic proliferation that can be mistaken clinically as sarcoma, given its rapid growth. As its name implies, nodular fasciitis was originally described involving the fascia. Although rare dermal cases have been described, this is the first report of a dermal polypoid variant known to us, thus extending the presentations of this condition.
