Russell body gastritis.

We report a case of Russell body gastritis in a 28-year-old male who presented with abdominal pain and rectal bleeding. Endoscopy showed erosions with edema and vascular congestion in the gastric body and antrum. The biopsy showed chronic gastritis with plasma cell infiltration of the lamina propria. Many plasma cells contained cytoplasmic Russell bodies which stained positive for CD138, CD79a, Kappa and lambda light chains. The Russell bodies were negative for pancytokeratin, excluding signet ring cell carcinoma. Russell body gastritis is an uncommon, benign reactive condition. PMID: 31388200 [PubMed - in process]
