Two Cases of Russell Body Gastritis Treated by Helicobacter pylori Eradication

ABSTRACT

Russell body gastritis was first defined in 1998, but not many cases have been reported since then. The exact causes and process of this condition are unknown yet; however, considering the reported cases, it has been highly suggested to have correlation with Helicobacter pylori infection. Russell body gastritis has a non-specific clinical presentation of gastritis such as gastric mucosal edema in the macroscopic view. It can be mistaken as xanthoma, signet ring cell carcinoma, or a malignant lymphoma including mucosa-associated lymphoid tissue lymphoma and plasmocytoma. Russell body gastritis features polyclonal immunoglobulin and is differentiated from Mott cancer, of which immune globulin has monoclonal aspect. Authors report here two cases of Russell body gastritis with examined endoscopic findings as well as a review of related literature on the association of all reported cases of Russell body gastritis with H. pylori infection.
