A 60s male was referred for the further examination of a gallbladder tumor. He underwent left nephrectomy for renal cell carcinoma a year before. Contrast-enhanced computed tomography and endoscopic ultrasonography revealed an enhanced elevated lesion in the fundus of the gallbladder. Laparoscopic cholecystectomy was performed, and the pathological diagnosis was metastatic renal cell carcinoma of the gallbladder.
Metastatic carcinomas of the gallbladder are rare. The most common primary tumor metastasized to the gallbladder was renal cell carcinoma, followed by malignant melanoma, and gastric cancer/breast cancer. Metastatic lesions of renal cell carcinoma and malignant melanoma in the gallbladder often present elevated lesion, whereas those of the gastric and breast cancer often present wall thickening. The morphology of metastatic gallbladder tumors might depend on the primary site of the tumor.
