We report a case of ureteral carcinoma in which port site metastasis was found after a laparoscopic nephroureterectomy. The patient was a 77-year-old woman with a chiefcomplaint ofgross hematuria. A tumor was found in her left ureter by computed tomography (CT). The patient was diagnosed with a left ureter carcinoma with T2N0M0 or less. She underwent retroperitoneoscopic radical nephroureterectomy. The pathological diagnosis was an urothelial carcinoma, Grade 2, pT2Nx. She was carefully followed up without any adjuvant therapy. At 26 months postoperatively, a subcutaneous tumor was found at a port site without any disseminated disease or distant metastasis by CT and positron emission tomography-CT (PETCT). She underwent surgical resection ofthe subcutaneous tumor. Pathological diagnosis was port site metastatic urothelial carcinoma. She had no recurrence or metastasis at 24 months after the surgical resection without any adjuvant therapy.
