Core Tip

Core tip: The rare condition extramedullary plasmacytoma involves the gastrointestinal tract, usually liver, in approximately 10% of cases. A role for the pancreas is particularly rare. Pancreatic tumors can be identified radiologically, although it is impossible to discriminate between extramedullary plasmacytoma and adenocarcinoma. The use of endosonographic fine needle aspiration to acquire a histological sample from the pancreatic mass to confirm diagnosis is feasible and informative even in the presence of inoperable mass image.
