Duodenal plasmacytoma: a rare extramedullary localization simulating carcinoma of the head of the pancreas.Postgrad Med J. 1994 May; 70(823):378-9.PM
Plasmacytomas occurring in extramedullary sites are rare tumours, particularly so when located in the gastrointestinal tract. We report the case of a solitary extramedullary plasmacytoma arising in the duodenum and simulating a carcinoma of the head of the pancreas. Diagnostic and treatment options are discussed.
