Rare secondary tumors of the pancreas

Secondary neoplasms involving the pancreas are less common than primary neoplasms. The pancreas is rarely the only metastatic site and metastases can reach the pancreas by lymphatic or hematogenous routes. Several tumors have been demonstrated to metastasize to the pancreas; however, there are differences in the prevalence of the various tumor types that colonize the pancreas, depending upon the population considered (autopsy records vs. surgical specimens).
