Lymphoid aggregate polyp.

A 54-year-old man was found to have a 2-cm semipedunculated polyp in the sigmoid colon during screening colonoscopy. The polyp was removed by endoscopic mucosal resection. Histologic examination of the resected polyp revealed diffuse epithelial infiltration by discrete aggregates of lymphoma cells.

Background/Aim Lymphoid follicles hyperplasia (LH) is sometimes observed in the normal colon as small, round, yellowish-white nodules. LH is associated with food hypersensitivity and bowel symptoms and histologically characterized as intense infiltration of lymphocytes or plasmacytes. It is suggested that LH represents inflammatory immune response in the colonic mucosa.The aim was to study the role of lymphoid aggregates in the migration and transition of BMDCs in both healthy colons and non-specific colitis (NSC).

Find a Doctor. An intestinal polyp is a growth that sticks out of the lining of the colon or rectum. Risk factors include a family history of polyps or colon cancer.On pathology examination, the villiform polyp from the sigmoid colon was identified as a CMSEP. The polyp was lined by normal-appearing colonic mucosa, and the underlying submucosa contained increased blood vessels and inconspicuous lymphatic channels (detected on immunohistochemistry stain for D2-40), without significant inflammation in the lamina propria (Figure (Figure2). 2).The lesions ranged from thickened mucosal folds, irregular appearing mucosa, friable erythematous mucosa or polyps. Imaging studies showed lesions limited to the GI tract. Histologically, the lamina propria was expanded by a dense, non-destructive lymphoid infiltrate composed of small mature appearing lymphocytes.The eLTs were discovered in the majority of grade 2 (64.29%) and 3 (92.31%) lymphoid aggregates but absent in grade 1 lymphoid aggregates . The eLTs presented more frequently in eosinophilic (20.69%) and noneosinophilic (17.31%) NPs compared with control subjects (3.70%, Fig 2).

A polyp with more than 75% villous features, i.e., long finger-like or leaf-like projections on the surface, is called a villous adenoma, while tubular adenomas are mainly comprised of tubular glands and have less than 25% villous features.

Ectopic lymphoid tissues (eLTs) and associated follicular helper T (T FH) cells contribute to local immunoglobulin hyperproduction in nasal polyps (NPs).Follicular regulatory T (T FR) cells in secondary lymphoid organs counteract T FH cells and suppress immunoglobulin production; however, the presence and function of T FR cells in eLTs in peripheral diseased tissues remain poorly ...INTRODUCTION. Primary malignant gastrointestinal lymphomas are uncommon, making up less than 1% of all malignant colorectal neoplasms. 1 Mucosa-associated lymphoid tissue (MALT) lymphoma is a rare type of non-Hodgkin B cell lymphoma most often found in the gastrointestinal tract, principally the stomach, although extragastric locations have been reported including the small bowel, colon, and ...Few polyps arise from submucosa including lipomas, carcinoids or lymphoid aggregates. Most commonly, however, they result from the mucosa, and they can be adenomatous, serrated, or non-neoplastic. Hyperplastic polyps are very common and have a very low malignant potential. They are encountered more in the distal colon.Nodular lymphoid hyperplasia (NLH) of the gastrointestinal tract is characterized by the presence of multiple small nodules, between 2 and 10 mm in diameter. Although it may be detected in the stomach, large intestine or rectum [ 1 ], it is more often distributed in the small intestine. Histologically, NLH is defined by markedly hyperplastic ...One of every 10 paraffin sections was stained with hematoxylin-eosin to screen for the presence of lymphoid aggregates by two independent investigators. ...

A representative example (Case no. 3) of using whole slide imaging in measuring various parameters. a, The density (D) of follicles is measured by dividing the number of lymphoid follicles by the total surface area of the biopsy specimen (with summation of the measurements from all the tissue fragments; D = number of follicles/area; in this case, 2/(3.3 + 2.7) = 0.3333).
