Primary Clean Cell Renal Carcinoma Metastasis to the Gallbladder: A Case Report
1Hepatobiliary Surgery, The Fourth Hospital of Hebei Medical University, Shijiazhuang, CHN.
Abstract:
Renal cell carcinoma (RCC) metastasis to the gallbladder is exceedingly rare. A 60-year-old man with a history of RCC underwent cholecystectomy for incidental gallbladder polyps. Pathology confirmed metastatic RCC via immunohistochemistry staining. Despite surgery, bone lesions suggestive of metastasis emerged at the eight-month follow-up. This case underscores the importance of vigilance for atypical metastases in RCC survivors and the critical role of histopathology in avoiding misdiagnosis.
