Plasmocytoma presented as pancreatic head mass

Abstract

Multiple myeloma is a malignant tumour characterized by proliferation of a single clone of plasma cells, this cell line will produce large amount of ineffective immunoglobulins that are ineffective at fighting infection resulting in immunosuppression. These are medullary tumours most of the time; however, in rare cases they may arise extra medullary. The incidence of extramedullary plasmocytoma is about 5% and they arise in the chest most of the time; but they can also arise in other body systems like gastrointestinal system, which is involved in 10% of the time. We present a very rare case of primary plasmocytoma involving the pancreas. According to our research, there are only 25 cases of primary pancreatic plasmocytoma reported in english literature.
