They are the most common colonic polyp (75 - 90% of colon polyps), typically 1 - 5 mm in greatest dimension, rarely 1 cm or greater. Most common in left colon, especially the rectum; often multiple.

Mucosal hyperplasia, hyperplastic polyp and sessile serrated polyp have quite similar appearances in the appendix .

Terminology. Serrated polyp is currently preferred terminology over sessile serrated adenoma / polyp, as appendiceal lesions appear to have different mutations than similar lesions in the colon ( Am J Surg Pathol 2016;40:14 ) Presence or absence of dysplasia should be noted Mucosal hyperplasia, hyperplastic polyp and sessile serrated polyp/adenoma have quite similar appearances in the appendix They are distinguished architecturally as all lack cytologic dysplasia Architectural distortion due to obstructive changes may make the distinctions difficul The surgical pathology files of the Ohio State University Medical Center, Columbus (1989 to 2008), were searched for appendiceal lesions originally diagnosed as any of the following: mucosal hyperplasia, hyperplastic polyp, sessile serrated adenoma, serrated adenoma, villous adenoma, tubular adenoma, tubulovillous adenoma, cystadenoma, or mucocele Hyperplastic Polyp. Introduction: Hyperplastic polyps (HPs) are benign epithelial lesions that are usually seen in 6th or 7th decades of life. In asymptomatic individuals older than 50 years undergoing colonoscopy, HPs are seen in about 10% of cases. The prevalence rate of HPs from autopsy studies is 20% to 35%
Sporadic duodenal polyps are uncommon, being found in up to 5% (0.3-4.6% of cases) of patients referred for upper gastrointestinal endoscopy. They are often discovered incidentally and the majority of patients are asymptomatic. The most common lesions necessitating removal are duodenal adenomas which should be differentiated from other mucosal lesions such as ectopic gastric mucosa, and. Young RH, Gilks CB, Scully RE.

Am J Surg Pathol. 1991 May;15(5):415-29. Misdraji J, Yantiss RK, Graeme-Cook FM, Balis UJ, Young RH Similar to adenomas (or adenomatous polyps) of the colon, Appendiceal Adenomas may be tubular, villous, or tubulovillous. However, the frequently occurring type noted in the appendix is the sessile serrated polyp/adenoma. Hyperplastic polyps are also occasionally seen in the appendix The spectrum of lesions with a serrated growth pattern is subdivided into hyperplastic polyps, mixed dysplastic/hyperplastic adenomas and serrated adenomas. Other types of polyp include inflammatory polyps, juvenile polyps, Peutz-Jeghers or other types which are included under not otherwise specified and described in free text Cervical polyps. From Libre Pathology. Jump to navigation Jump to search. Cervical polyps are common entities that can be bothersome and are thus removed by a gynecologist. The vast majority are benign.

Twenty-five patients with mucinous tumors of the ovary and appendix were studied. The average age of the patients was 52 years, and the ovarian and appendiceal tumors were discovered synchronously in all but two cases. The majority had either a pelvic mass or abdominal or pelvic pain. A high frequen Comments: Antrochoanal polyp is a distinctive subtype of inflammatory nasal polyp that makes up 3%-6% of all sinonasal polyps.It is more common in men and usually occurs in teenagers and young adults.The patients often give history of bilateral maxillary sinusitis and/or allergies. It arises in the maxillary sinus and extends via its ostium into the nasal cavity Nonneoplastic polyps include hyperplastic polyps, inflammatory polyps and hamartomatous polyps. Nonneoplastic polyps typically do not become cancerous. Neoplastic polyps include adenomas and serrated types. These polyps have the potential to become cancer if given enough time to grow. Most of these colon polyps are called adenomas Hamartomatous polyps of gastrointestinal tract occur sporadically as well as components of genetic or acquired syndromes.When occurring in the syndromic setting, some of them are associated with germline mutations in tumor suppressor genes or oncogenes and carry increased risk of malignancies.Juvenile polyps and polyps associated with Peutz-Jeghers Syndrome will be addressed in this section
True (i.e., well demarcated) polyps are rare. 10,16,21,70 In hyperplastic polyps, the crypts are elongated and have serrated luminal outlines (Figs. 24-11 and 24-12). Mitotic activity is marked in the basal zones of the crypts but is absent from the apical third of the crypts. 16 The muscularis mucosae beneath a hyperplastic polyp is normal Neoplastic polyps show epithelial dysplasia by definition and include adenomas and carcinomas. Adenomas can be tubular, tubulovillous, or villous based on the glandular architecture. Serrated adenomas, which are related to hyperplastic polyps, have malignant potential and are now considered neoplastic. 1

Cardiovascular system; Digestive syste A hyperplastic polyp is a growth of extra cells that projects out from tissues inside your body. They occur in areas where your body has repaired damaged tissue, especially along your digestive tract If there is no luminal neoplastic/dysplastic epithelium after comprehensive histological evaluation, then the appendix is reactive or hyperplastic, represents a simple non-neoplastic mucocele (i.e. retention cyst), or may harbor a serrated polyp (this category includes hyperplastic polyps and sessile serrated adenomas) A subset of these will contain lymphoid tissue, which may be mentioned in the pathology report. To aid in understanding what is meant when lymphoid tissue is described in the pathology report, we provide the following definitions: Lymphoid tissue: A general term to describe a collection of B-cells, T-cells, and support cells. Lymphoid tissue is. Hyperplastic polyps: These are defined by the activity of cells in the tissue mass. Hyperplasia (fast growth) simply means that there is an abnormal increase in the numbers of cells resulting in the growth of a polyp. Despite their rapid growth, hyperplastic polyps are unlikely to become cancerous

Hyperplastic polyps have virtually no malignant potential. In a study, diagnostic sensitivity of detecting adenomas was 69%, while specificity (the accurate diagnosis of hyperplastic polyps) was 86% (Goodman 1998, Neale 1987).
