Abstract:
The clinicopathologic features of malignant lymphoma of the small intestine were reviewed. Genetically, characteristic chromosomal translocations have been identified in several B-cell lymphomas, such as t (11 ; 18)/API2-MALT1 in MALT lymphoma, t (14 ; 18)/IGH-BCL2 in follicular lymphoma, or t (3 ; 14)/BCL6-IGH in diffuse large B-cell lymphoma (DLBCL). Histologically, DLBCL is most frequently observed, and T-cell lymphoma and follicular lymphoma are more frequent in small intestinal cases than in gastric cases. Macroscopically, small intestinal lymphomas are classified as polypoid, ulcerative (including stricturing, non-stricturing and aneurysmal forms on radiography), multiple lymphomatous polyposis, diffuse, or other types. A significant correlation is observed between these macroscopic/radiographic and histologic types. The therapeutic strategy, such as surgery, chemotherapy, antibiotics or watch-and-wait, should be determined based on the disease extent, histologic type, and clinical stage.

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...
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...
Small Intestine
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique C-shape wraps...

Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
