Intravascular fasciitis: a case report of an intraoral location.

Nodular fasciitis is a benign reactive fibroblastic proliferation which usually arises from the superficial or deep fascia of the extremities and trunk. In 1981 a distinct variant, intravascular fasciitis (IVF), was reported which possessed the same clinical and histological features of more ordinary forms of nodular fasciitis but, in addition, had a striking involvement of associated arteries and/or veins. A case of intraoral IVF is presented and its clinical and histologic features are compared with those of IVF found elsewhere in the body. A brief discussion of etiology and differential diagnostic considerations is also included.
