METASTATIC CARCINOMA OF THE COMMON BILE-D UCT FROM RENAL-CELL CANCER PRESENTING AS AN INTRALUMINAL POLYPOID MASS

The authors report the second case to date of metastatic carcinoma of the common bile-duct from renal cell cancer presenting as an intralumi nal polypoid mass. Obstructive jaundice developed in a 55-year old wom an 14 years after nephrectomy for renal cell carcinomma. The diagnosis of polypoid tumor of the common bile-duct was established by sonograp hy, endoscopic retrograde cholangiopancreatography and CT-scan. Pallia tive resection was performed. Postoperative histological examination r evealed the resected tumor to be identical to the clear cell type of r enal cell carcinoma. The postoperative course was marked by the develo pment of distant metastases 6 months later. Diagnosis and therapeutic features of metastatic malignant biliary obstruction are discussed.
