"Approximately one third of all cases of gastric MALToma show variable degrees of plasma cell differentiation, occasionally plasma cells constitute the major population in the tumor. As surgical resection has been the standard treatment for gastric plasmacyotoma, this case highlights the need for caution. If H. pylori infection is found in a patient with a gastric plasmacytoma, it should be eradicated as a first line of therapy before surgery is considered."
