Concurrent primary cardiac tumors of differing histology and origin: case report with literature review.

Primary cardiac tumors are rare and are diverse in histology and anatomic origin. Approximately 75% are benign, and nearly 50% of these are myxomas. Herein, we report concurrent myxoma and papillary fibroelastoma, which tumors were found attached to the left atrial septum and aortic valve, respectively. Concurrent primary cardiac tumors of differing histology and origin are rare, and, to our knowledge, this is one of the few such cases reported in the medical literature.
