Lymphoglandular complex is a normal structural entity of the large bowel and it acts as a local receptor of antigenic material for future immune recognition.These were: (1) histotopography, that is, localisation of the lymphoid aggregates within the bone marrow space; (2) relation to the surrounding tissue: margination or interstitial spillage of lymphoid cells; and (3) increase in reticulin fibres. CONCLUSIONS: A combined diagnostic procedure identifying several distinctive features, in particular ...Clues favoring a diagnosis of lymphoma over reactive lymphoid hyperplasia include: (i) tissue effacement by confluent sheets of lymphoid cells (even with polyp formation), (ii) infiltration and disruption of glandular units (i.e. “lymphoepithelial lesions”; LELs), (iii) atypical follicles, follicular colonization or expanded mantle zones ...What is a lymphoid polyp? A lymphoid polyp is an often benign, focal proliferation of gut associated lymphoid follicles. Lymphoid polyps are rarely found in adults and are usually found in terminal ileum or rectum. These polyps are usually asymptomatic though possible association with development of malignant lymphoma has been described.Results. Polyps with subtle changes comprised 12% of all polyps. All polyps were sessile and small (<0.5 cm) and were located predominantly in the distal colon (60%).

Comment Here.A major proportion of the workload in many histopathology laboratories is accounted for by endometrial biopsies, either curettage specimens or outpatient biopsy specimens. The increasing use of pipelle and other methods of biopsy not necessitating general anaesthesia has resulted in greater numbers of specimens with scant tissue, resulting in problems in assessing adequacy and in interpreting ...Lymphoid hyperplasia. Lymphoid hyperplasia is an increase in the number of normal cells contained in the lymph nodes. These cells are called lymphocytes. This can occur as a reaction to infection with bacteria, viruses, or other types of germs. This may or may not be normal, depending on why it occurs. In Crohn's colitis, the number of lymphocytes and plasma cells in the lamina propria and of MLA is substantially increased.

A polyp of the colon refers to a protuberance into the lumen above the surrounding colonic mucosa. Colon polyps are usually asymptomatic but may ulcerate and bleed, cause tenesmus if in the rectum, and, when very large, produce intestinal obstruction. Colonic polyps may be neoplastic (eg, adenomas) or non-neoplastic (eg ...Our binary approach (serrated vs adenoma) and surveillance model means that any polyp, including normal and lymphoid aggregates proximal to the sigmoid will be categorized as an SRL (serrated vs. adenoma) by our CNN. This strategy therefore biases toward OP-shortened surveillance intervals and discordance with TP.A lymphoid aggregate was defined as accumulation of lymphocytes and plasma cells without a germinal center. The lymphoid follicles and aggregates were categorized in 3 groups: (1) sub-epithelial small, present just below the epithelium and occupying half or less of the lamina propria; (2) basal small, present just above the muscularis mucosae ....
