Gallego et al. Journal of Medical Case Reports 2011, 5:11 http://www.jmedicalcasereports.com/content/5/1/11 prognosis and correct treatment of patients with OC are required as more cases are reported. Conclusion OC is an extremely rare malignancy in salivary glands, and standard treatment and prognosis is unclear. Clini- cians should perform a careful follow-up, as distant metastasis appeared to be the most important prognos- tic feature. Consent Written informed consent was obtained from the patient for publication of this case report and any accompany- ing images.
