Sigmoid adenocarcinoma with renal metastasis.
We report a case of a 75-year-old man submitted to a rectosigmoidectomy and partial cystectomy because of a sigmoid cancer and colovesical fistula. Seven months later and after four cycles of adjuvant chemotherapy, a lesion was detected in the kidney. Histology revealed tubular adenocarcinoma, which meant sigmoid cancer metastasis. Kidney metastases are very rare in colorectal cancer (CRC), but may be generally associated with an unfavorable prognosis. Thus, patients with metastatic CRC and kidney tumors are a diagnostic and therapeutic challenge.
