Prostate cancer is one of the most common malignancies in the United States. In 2014, it is estimated that 233,000 men were diagnosed with prostate cancer, encompassing 14% of all new cancer cases, and 29,480 men died from the disease. Prostate cancer most commonly metastasizes to regional lymph nodes and bone. A post-mortem survey characterizing the extra nodal metastatic sites of prostate cancer demonstrated that irrespective of clinical symptoms, the more commonly involved sites included bone, lung, liver, pleura, adrenal glands, peritoneum and meninges, however 0.5% of patients were found to have gallbladder metastases. Different malignancies have been reported to metastasize to the gallbladder, including melanoma, renal cell carcinoma, and non-small cell lung carcinoma, and in most cases these patients present with acute cholecystitis.
