Gallbladder metastasis from primary renal malignancy: case report and review

Abstract

Gallbladder metastases are rare, that too from a renal malignancy are further rare. Renal cell carcinoma (RCC) accounts for 3% of adult malignancies and >30% of cases are already metastatic by the time of presentation. Neither gallbladder is a usual site for RCC to metastasize nor is clear cell RCC common in gallbladder secondaries. We report one such case of a 50-year-old man who was incidentally diagnosed to have left sided renal cell carcinoma and developed gallbladder and lung metastases detected in follow-up imaging. Patient underwent radical nephrectomy followed by extended cholecystectomy later on. And presently is receiving targeted therapy for pulmonary metastases.
