Abstract
|
|
|
Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancy. 25% to 57% of RCC patients exhibit overt evidence of metastatic disease at initial presentation. Metastases to the gallbladder is uncommon and usually detected in only 0.4-0.6% of autopsies. We report the case of a 58-year-old man who presented with a metastasis in the gallbladder from RCC. He had undergone went a right nephrectomy four years ago. There was no evidence of metastasis. A follow-up abdomen CT scan taken three years after operation showed a polypoid lesion within the gallbladder. The size of the polypoid lesion had increased at the follow-up CT and the enhancement pattern of lesion became similar to that of RCC. A Cholecystectomy was performed. Histopathological examination revealed the polyp was clear cell carcinoma of metastatic origin from kidney.
