Abstract

DIRECT invasion of adjacent colon by contiguous hypernephroma is seldom clinically notable, but it is occasionally identified during nephrectomy for locally advanced lesions,1 and in recurrence of previously resected hypernephromas.2,3 In such instances, the renal origin of the lesion is generally evident. It is rare for an otherwise occult hypernephroma to be diagnosed as a primary colon carcinoma. Failure to recognize the renal origin of the lesion before surgery can result in extensive improperly directed surgery.
