A 64-year-old woman received nephrectomy and lymph expurgation surgery for renal cell carcinoma on Jury 1, 1981. The pathologic diagnosis was adenocarcinoma of the clear cell type at Robson's stage 2. She next visited the Department of Gastroenterology complaining of stomach discomfort on November 5, 1981. Stomach cancer of Borrmann's type IV was identified in the lesser gastric curvature, but only biopsy was performed because it was inoperable. The pathologic diagnosis was undifferentiated adenocarcinoma. On January 23, 1982, there was microscopic hematuria. A cystoscopic examination revealed one soy bean-sized, smooth, pedicle tumor to which coagula were partially adhered in the center of the triangular region. After TUR-Bt performed on March 3 the pathologic diagnosis was adenocarcinoma of the clear cell type with no submucosal infiltration. Based on these findings, the patient was diagnosed as having suffered metastasis of renal cell carcinoma to the bladder. She died of bleeding from stomach cancer on June 15. Based on the fact that the tumor was localized in the bladder mucosa, implantation through the urinary tract was strongly suspected as the metastatic route of the renal cell carcinoma to the bladder.
一名64岁女性于1981年7月1日接受了肾细胞癌肾切除术及淋巴结清扫术。病理诊断为透明细胞型腺癌，处于罗布森分期2期。1981年11月5日，她因胃部不适前往胃肠病科就诊。在胃小弯处发现了Borrmann IV型胃癌，但因其无法手术，仅进行了活检。病理诊断为未分化腺癌。1982年1月23日，出现镜下血尿。膀胱镜检查发现三角区中央有一个黄豆大小、表面光滑、有蒂的肿瘤，肿瘤中央部分附着有凝血块。3月3日进行经尿道膀胱肿瘤电切术（TUR-Bt）后，病理诊断为透明细胞型腺癌，无黏膜下浸润。基于这些发现，患者被诊断为肾细胞癌转移至膀胱。她于6月15日死于胃癌出血。基于肿瘤局限于膀胱黏膜这一事实，强烈怀疑肾细胞癌通过尿路种植转移至膀胱。
