title: Sigmoid adenocarcinoma with metastases to the kidney: Report of a rare case and review of the literature.
abstract: Distant metastases from colorectal cancer (CRC) most frequently spread to the liver and lungs. CRC metastasis to the kidney is extremely rare and may be generally associated with an unfavorable prognosis. Thus, patients with metastatic CRC and kidney metastasis are a diagnostic and therapeutic challenge. The present study reported the case of a 42-year-old male with a local recurrence of CRC following sigmoid resection with partial mesorectal excision, which had infiltrated the urinary bladder, requiring partial resection of the urinary bladder wall. After 4 years, the patient developed a recurrent tumor localized in the upper pole of the left kidney and underwent left nephrectomy. The patient remained disease-free 6 months after the surgery.
