Russell body gastritis is characterized by accumulation of plasma cells, filled with Russell bodies, in the gastric mucosa. Twelve cases have been reported in the English language medical literature. Its association with Helicobacter pylori gastritis or immunosuppression is known. The present case is the third to be reported in association with HIV infection. An 82-year-old male presented with dyspepsia, loose stools, loss of appetite and weight. Computed tomography scan showed esophageal and gastric wall thickening. Gastrointestinal endoscopy revealed gastritis. Microscopic examination of the biopsy revealed gastric mucosa with diffuse plasma cell infiltration in the lamina propria, associated with large eosinophilic Russell bodies. Immunoperoxidase stains revealed positivity for CD 138 and lambda and kappa chains. Special stain for Helicobacter pylori and immunostain for CD68 were negative. The differential diagnoses include plasmacytoma and mucosa associated lymphoid tissue (MALT) lymphoma with plasmacytic differentiation, which are entities with different prognostic and therapeutic implications.

We report a rare case of a gastric plasmacytoma treated with endoscopic resection and oral thalidomide therapy. A 70-year-old man was admitted to our hospital with indigestion. He had no specific medical history and unremarkable laboratory results. Gastroendoscopic findings revealed a focal, erythematous, flat elevated lesion in the anterior wall of the stomach antrum. A biopsy revealed atypical lymphocytes. Endoscopic submucosal dissection (ESD) with an insulation-tipped knife was performed 45 days after diagnosis. Radiological and hematological evaluations, including a bone marrow biopsy, were performed and showed no involvement of other organs. The patient was diagnosed with extramedullary gastric plasmacytoma. Follow-up gastroendoscopy was performed three times during a 2-year period and showed nonspecific ESD scarring. The patient's condition was found to be stable.
