Metastatic tumors of the endocardium: report of three cases.

Because of their apparent rarity and the tendency of clinicians to lump indicative signs and symptoms under the heading of metastatic disease, metastatic tumors of the endocardium are seldom mentioned in the literature, in the three cases presented herein, endocardial metastases were evident at autopsy. In one case of malignant melanoma, clinical evidence for endocardial involvement was present in life. This article also presents a case of endocardial involvement by Wilms' tumor and a case of endocardial involvement by hypernephroma with pulmonry tumor emboli.
