Abstract
-
Two unusual cases of metastasis of carcinoma to carcinoma are reported. The initial malignancies, an adenocarcinoma of the rectum and a duct carcinoma of the breast, were found to have metastasis to a clear cell carcinoma of the kidney. The various theories on the peculiar tendency for the renal cell carcinoma to be the most common host tumor for other primary carcinoma are commented upon briefly.
