The surgical specimen revealed multiple, large, tree-like branching polypoid masses, with elongated or pedunculated stalks or a wide broad base, measuring up to 14.0×5.0×4.5 cm in dimensions of the largest polypoid mass (Fig. 2A).Upon microscopic examination of the lesions, most of the polyps had long, elongated, and loose or fibrotic submucosal elongated stalks, while some were sessile.The rectal tonsil: a reactive lymphoid proliferation that may mimic lymphoma.

Benign lymphoid polyps are uncommon lesions of the small bowel and the colon to a lesser degree that are mostly found in children. There are only few reported cases in adults in which the lesions were predominantly polypoid and described as lymphonodular hyperplasia.

C, The proliferation has abundant collagen as well as smooth muscle bundles and blood vessels. A polyp is a projection (growth) from the inner lining into the lumen (hollow center) of the colon or rectum. There are different types of polyps, which look different when seen with a microscope. Most polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps.Tertiary lymphoid structures (TLS) are ectopic aggregates of lymphoid cells in inflamed, infected, or tumoral tissues that are easily recognized on an H&E histology slide as discrete entities, distinct from lymphocytes. TLS are associated with improved cancer prognosis but there is no standardised method available to quantify their presence. Previous studies have used immunohistochemistry to ...Severe benign lymphoid hyperplasia (LH) is unusual in the head and neck region, but the diagnosis of LH is of clinical importance as it may be confused with malignant lymphoma, both on clinical examination and pathologically. While the etiology is poorly understood, a number of previous theories exist, which are included here in the context of ...

The most predominant primary duodenal lymphoma was follicular lymphoma. In this review, we provide an update of the diagnosis and man-agement of representative lymphoma subtypes occurring in the duodenum: Follicular lymphoma, diffuse large B-cell lymphoma, extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue, mantle cell ...Lymphoid polyps (present in 15% of patients) are hyperplastic submucosal lymphoid aggregates, most likely due to a nonspecific infection (exposure to bacteria and viruses). Submucosal lymphoid tissue is prominent in children, particularly in the distal ileum (Peyer patches).Essential features. Endometrial stromal plasma cells required for the diagnosis of chronic endometritis. Chronic endometritis is implicated in infertility and recurrent pregnancy loss. Acute endometritis typically represents ascending infection from lower genital tract. Xanthogranulomatous endometritis usually associated with cervical stenosis.In agreement with our findings, these lymphocyte aggregates have been previously described in patients with IPF as "ectopic organized lymphoid structures," and have been shown to consist of nonproliferating, but activated CD3+ and CD20+ cells. 7 Mechanistic research from numerous laboratories has indicated that pulmonary lymphocytes may ...Mucosal and sub-mucosal lymphoid aggregates were identified (Figure 5A, 5B).

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).

Around 75% of colorectal cancers start from adenomatous polyps, and about 80% of all colon polyps are adenomas. But only about 5% of adenomas are actually malignant . The risk of a random, average-size colon polyp becoming cancerous is estimated to be 8% over 10 years and 24% over 20 years.

Abstract. Lymphoglandular complexes (LGCs) are lymphoid nodules containing intestinal mucosa, present in close apposition to muscularis mucosae or submucosa. Rarely, colorectal adenomas involve submucosal LGCs, simulating invasive adenocarcinoma with associated submucosal lymphoid aggregates, and presenting a diagnostic pitfall.Pedunculated: This is a raised, mushroom-like growth that is attached to the lining of the colon by a long, thin stalk (peduncle).Because they are raised, pedunculated polyps are easier to spot and remove, and less likely to turn cancerous. Sessile: This is a flat or dome-shaped growth that sits on the colon's lining.Sessile polyps are more likely to become cancerous, in part because they are ...Background: 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 ...Conventional endometrial, endocervical, or adenomyomatous pedunculated, or sessile lesion with histologic features diagnostic of polyp.
