Biliary Obstruction Secondary to an Extramedullary Plasmacytoma of the Pancreas

Extramedullary plasmacytoma (EMP) is an uncommon neoplastic disorder arising from B-cell lymphocytes and comprises 3% of the plasma cell neoplasms. Ninety percent of the cases are encountered in the head and neck regions. The involvement of the pancreas is rare and generally develops as secondary multiple myeloma (MM). To date, four cases of EMP of the pancreas, which developed as secondary solitary bone plasmacytoma, have been reported in the literature. We decided to present this rare case, which was diagnosed and treated at our clinic.
