Endometrial cancer commonly metastasizes to the pelvic and para-aortic lymph nodes, vagina, peritoneum, and lungs. Unusual sites of metastasis include the bone, brain, abdominal wall, muscles, and intra-abdominal organs. To our knowledge, there have been no documented cases of synchronous or metachronous metastasis of endometrial cancer to the renal pelvis or colon. Metastatic tumors in the renal pelvis and colon indicate nonspecific radiological findings, making them difficult to distinguish from primary tumors. We describe a case of a 55-year-old female previously treated for endometrial cancer, who was subsequently found to have metastatic masses in the renal pelvis and colon. The two masses were initially misidentified as primary urothelial carcinoma and colon adenocarcinoma.
子宫内膜癌通常转移至盆腔和腹主动脉旁淋巴结、阴道、腹膜及肺部。不常见的转移部位包括骨骼、脑、腹壁、肌肉及腹腔内器官。据我们所知，尚无子宫内膜癌同步或异时转移至肾盂或结肠的文献记载病例。肾盂和结肠的转移瘤表现为非特异性影像学特征，难以与原发性肿瘤相鉴别。我们报告一例55岁曾接受子宫内膜癌治疗的女性，随后发现其肾盂和结肠有转移瘤。这两个肿物最初被误诊为原发性尿路上皮癌和结肠腺癌。
