title: Extraabdominal desmoid tumor appearing following resection of thoracolumbar schwannoma.
abstract: The authors report the case of an adult female patient who developed a thoracic paraspinous desmoid tumor (aggressive fibromatosis) located just cranially to the incision scar of the previous surgery for resection of a spinal schwannoma. To the best of the authors' knowledge, this is the first report of an extraabdominal desmoid tumor occurring after resection of a spinal schwannoma. Desmoid tumors develop from muscle connective tissue, fasciae and aponeuroses. They are known to occur in association with surgical scars or implants. Incidence of this tumor is low. The etiology is still uncertain. Although rare, this distinctive tumor should be kept in mind in the differential diagnosis of palpable masses and especially those occurring around the previous skin incisions.
