Unusual presentation of infection by Helicobacter pylori: gastritis associated with Russell bodies, infrequent and poorly understood pathology.

Russell bodies gastritis is a very rare disease, with few cases reported in literature, and characterized by the finding of plasma cells with eosinophilic intracytoplasmic inclusions in the gastric mucosa, called Mott cells. Although it has been partnered since its first description to Helicobacter pylori infection, it is important to considered differential diagnoses such as lymphoplasmacytic lymphoma, mucosa-associated lymphoid tissue (MALT) lymphoma, plasmacytoma and signet ring cell carcinom. In this case report, we address a patient with histologic confirmation and her follow up.
