Abstract:
Gastric MALToma is an extra-nodal marginal-type B-cell lymphoma. MALToma may occur secondary to chronic inflammation and autoimmunity. The most common gastrointestinal (GI) site of MALToma is the stomach, with approximately 50% of lesions occurring there. Synchronous upper and lower GI MALTomas rarely occur, with few cases reported. We present the case of a 67-year-old patient who presented asymptomatic and was found to have synchronous multifocal upper and lower GI MALTomas in the stomach, duodenum, terminal ileum, and sigmoid, which did not respond to H. Pylori eradication therapy.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Mucosal Barrier of the Stomach
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...
Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Histology of the Gastrointestinal (GI) Tract
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...
