Cardiac hamartoma. A case report.

A case of cardiac hamartoma, incidentally found at autopsy is described. The tumor was a protruded polypoid lesion located at the apex of the heart and was demarcated from the pericardial tissue. Microscopically this tumor was composed of dense collagenous tissue, mature adiposed tissue and proliferated blood vessels, intermingled with cardiac muscle cells, the latter being hypertrophic and disarrayed.
