Undifferentiated cardiac sarcoma metastatic to the maxilla: report of a case.

Primary cardiac sarcomas represent a group of rare and aggressive malignant mesenchymal neoplasms with a notoriously poor prognosis. They comprise a relatively small percentage of all primary neoplasms of the heart. Presenting clinical signs and symptoms associated with any cardiac sarcoma vary in accordance with the individual tumor’s particular site of origin in the heart (eg, left or right atrium, etc). These tumors typically invade contiguous vital anatomic structures and have a marked propensity for metastasis. Although there are only a limited number of published case reports of primary cardiac sarcomas, none mentions metastasis to the jaws. The following is a report of a case in which a cardiac sarcoma metastasized to the maxilla.
