Nodular fasciitis of the zygoma: A case report.

Nodular fasciitis (NF), a benign proliferation of fibroblasts, commonly presents as a solitary, well-circumscribed, rapidly growing soft tissue mass. It is most commonly located in the upper extremities, particularly on the volar aspect of the elbow, and on the chest and trunk. In adults, NF is rarely found in the head and neck region. Although benign, it can often be confused with a more malignant process and therefore must be properly diagnosed histologically. The cause of NF is unknown but an association with trauma may be present. Treatment is most commonly by local surgical excision, and recurrence is rare. A case of NF over the zygoma in a 60-year-old man not associated with trauma is presented.
