The most frequent sites for metastases from renal cell carcinoma are the lungs, bones and liver. Metas-tatic tumor to the colon is rare, and to the best of our knowledge, only five cases have been reported in the Japanese literature during the last one decade. A 67-year-old man, who had undergone a right radical nephrectomy for renal cell carcinoma about 4 years previously, experinced constipation. Barium enema examination and colonoscopy showed a mass on the sigmoid colon. On admission, no other abnormal findings than an increase in white blood cell count were noted. Biopsy revealed necrosis and granulation without any malignant findings. Angiography showed a hypervascular mass on the same site. Sigmoid colectomy with resional lymph nodes dissection (D3) was performed. The histopathological findings revealed metastasis from renal cell carcinoma. The patient had been disease-free for 11 months after the surgery. But we think that follow up for patients with a history of renal cell carcinoma must be lifelong.
