We report a rare case of secondary involvement of the gallbladder by metastatic renal cell carcinoma. A 71-year-old man was diagnosed as having a polypoid mass within the gallbladder when he underwent right nephrectomy for a renal cell carcinoma. A preoperative diagnosis of simultaneous carcinoma of the gallbladder was made, and extended cholecystectomy with regional lymphadenectomy was performed five months after the initial operation. Postoperative histological examination of the polypoid mass within the gallbladder and a pancreatic mass excised during the second surgery revealed these resected tumors to be identical to the clear cell type of renal cell carcinoma. We feel that this case presents synchronous involvement of the gallbladder and pancreas by metastatic renal cell carcinoma of the right kidney.
我们报告一例罕见的转移性肾细胞癌继发累及胆囊的病例。一名71岁男性因肾细胞癌接受右肾切除术时，被诊断出胆囊内有一个息肉样肿物。术前诊断为胆囊同时性癌，在初次手术后五个月进行了扩大胆囊切除术及区域淋巴结清扫术。术后对胆囊内的息肉样肿物以及第二次手术中切除的胰腺肿物进行组织学检查，发现这些切除的肿瘤与肾细胞癌的透明细胞型相同。我们认为该病例表现为右肾转移性肾细胞癌同时累及胆囊和胰腺。
