Unusual spinal metastases from an adenoid cystic carcinoma of the maxillary sinus

Adenoid cystic carcinoma (ACC), the second most common cancer occurring in the sinonasal tract, is an aggressive malignancy with a poor five-year survival rate. Spinal metastases to the vertebral column related to this cancer are rare. This report presents a patient with maxillary sinus carcinoma with vertebral metastases at the thoracic level and compression of the spinal cord seven years after surgical resection of the primary tumor. Eleven years after detection of the primary tumor the patient is still able to walk. The role of decompression and/or fusion in spinal metastases with neurologic deficits is still under debate, although recent studies have confirmed the beneficial role of surgical intervention in selected patients. This report represents an example of modern individual treatment of an aggressive tumor in a palliative situation. The epidemiology, clinical findings, treatment and outcome of this atypical distant metastasis in long-term survivors are presented. (C) 2011 Elsevier Ltd. All rights reserved.
