GASQUE, Rodrigo A. et al. Gallbladder metastasis of clear cell renal carcinoma. Medicina (B. Aires) [online]. 2023, vol.83, n.6, pp.998-1002. ISSN 0025-7680.

Clear cell renal cell carcinoma (ccRCC) is an uncom mon malignant neoplasm that accounts for 3% of all malignant tumors in adults. This tumor exhibits a high tendency to develop synchronous or metachronous me tastases in different anatomical sites. Although gallblad der metastasis from ccRCC is extremely rare, sporadic cases have been reported in the medical literature. We present the case of a 78-year-old woman with a history of undifferentiated nasopharyngeal carcinoma, basal cell carcinoma, and ccRCC in the right kidney. She un derwent radical nephrectomy. Histopathological analysis confirmed the diagnosis of ccRCC without vascular or ureteral invasion. Two years later, during follow-up, a nodular lesion was detected in the gallbladder through computed tomography. Despite the absence of symp toms, surgical resection was decided. Laparoscopic cho lecystectomy was performed without complications. Histopathological examination confirmed the presence of ccRCC metastasis in the gallbladder. The patient had a favorable outcome and is currently under follow-up without recurrence.

Gallbladder metastasis from ccRCC is extremely rare, but surgeons should consider this possibility in patients with a history of ccRCC. Preoperative differential diagno sis between primary gallbladder carcinoma and ccRCC metastasis can be challenging and is often confirmed through histopathological examination. Complete sur gical resection is the best treatment option to achieve disease-free survival.
