Metastases to the pancreas account for less than 5 percent of all malignancies affecting the pancreas. The most common secondary malignancy of the pancreas is renal cell carcinoma. We report a patient presented with abdominal pain and weight loss. Computed tomography (CT) imaging showed pancreatic head mass. Biopsy from the mass showed prostate metastasis after 13 years from radical prostatectomy and Leuprolide therapy. This case demonstrates a rare location for prostate metastasis which was the pancreas. To our knowledge there are only six cases reported in literature. Due to increased long-term survival of prostate cancer patients, the frequency of metastases to the pancreas will likely increase. Therefore, clinicians need to be aware the pancreatic tumor may be secondary to an extrapancreatic malignancy.
