[Duodenitis Russell bodies. Review of the entity and associations beyond H. pylori].

Plasma cells known as "Mott cells" present non-secretable accumulations of immunoglobulins called "Russell bodies". Its presence is related to hematological neoplasms, but it can appear in chronic inflammatory processes. The most common occurrence within the digestive tract is the gastric antrum associated with H.

Endoscopic resection of rectal granular-cell tumor using elastic band ligation.

Granular cell tumor (GCT) is a rare neoplasm that develops in the gut's submucosal layer. We report the case of a male with a history of surgically excised colon neoplasm where a rectal polyp was identified during a follow-up endoscopy. The lesion, eventually identified as a GCT, was endoscopically removed by band ligation-assisted mucosectomy.
