[Primary pancreatic plasmacytoma]

Abstract

Extramedullary plasmacytomas are uncommon malignant plasma cell tumors that present outside the bone marrow; 80% of extramedullary plasmacytomas are located in the upper respiratory tract, and gastrointestinal plasmacytomas are rare. We present the case of an asymptomatic 65-year-old man in whom a pancreatic mass was found incidentally. The lesion was determined to be a pancreatic plasmacytoma after fine-needle aspiration cytology and surgical resection. No clinical, laboratory, or imaging findings indicative of multiple myeloma or association with other plasmacytomas were found, so the tumor was considered to be a primary pancreatic plasmacytoma.
