Summary of "Polyps of the colorectum : Non-neoplastic and non-hamartomatous."

Non-neoplastic and non-hamartomatous colorectal polyps or tumor-like lesions comprise a very heterogeneous group of changes in the colorectal mucosa or the colon wall. Mucosal prolapse-associated lesions and inflammatory polyps, which are predominantly associated with chronic inflammatory bowel disease, are the most prominent examples for polypoid lesions difficult to distinguish from neoplastic lesions such as adenomas, hyperplastic/serrated polyps/adenomas and invasive carcinomas. The considerably less frequent tumor-like lesions like heterotopias, endometriosis, amyloid tumors and pseudolipomatous changes are histologically often well defined and should be considered in the differential diagnosis of colorectal lesions. The etiology, endoscopic and histological appearance of these entities and their most important differential diagnoses are discussed.

Polyps! Polyps! And More Polyps! - The First Case of Cronkhite-Canada Syndrome in Malaysia.

Cronkhite-Canada Syndrome (CCS) is a syndrome characterised by a constellation of signs including but not limited to onychodystrophy of the finger and toe nails, skin hyperpigmentation and alopecia. E...

Morphologic characterization of hamartomatous gastrointestinal polyps in Cowden syndrome, Peutz-Jeghers syndrome, and juvenile polyposis syndrome.

The morphologic features of the gastrointestinal polyps in hamartomatous polyposis syndromes are poorly defined. Our aim was to better characterize the gastrointestinal hamartomas in these syndromes. ...

Colonic polyps and polyposis syndromes in pediatric patients.

Gastrointestinal polyps are commonly encountered during childhood and are one of the most common causes of rectal bleeding in this age group. Most polyps are benign and located in the colon, with the ...

Frequent co-occurrence of high-grade dysplasia in large flat colonic polyps (>20 mm) and synchronous polyps.

Large colonic polyps are associated with advanced dysplasia, but prevalence and characteristics of synchronous polyps in patients with large flat colonic polyps are poorly investigated. This study aim...

Gastric hyperplastic polyps coexisting with early gastric cancers, adenoma and neuroendocrine cell hyperplasia.

Gastric hyperplastic polyps (GHP) constitute up to 93% of all benign epithelial polyps of the stomach. The average probability of malignant transformation in GHP is 0.6-22% in large series. The aim of...

Confocal Probe-based Endoscopic Imaging, Colorectal Cancer, Gastrointestinal (GI) Pathologies

The recently developed endoscopic Confocal probe microscopy system allows imaging of surface epithelium during ongoing endoscopy (upper and lower) with the potential of immediate diagnosis...

Hot Snare Versus Hot Snare Polypectomy With Saline Injection for Colorectal Polyps

The complete removal of colorectal polyp is required to prevent tumor recurrence and development of potential interval cancers. However, several studies have shown high incomplete resectio...

Injection-Assisted Cold Snare Polypectomy Versus Endoscopic Mucosal Resection for Small Colorectal Polyps

Complete resection of neoplastic polyps is pivotal, as 8.8% to 50% of interval cancers may arise as a consequence of incomplete polypectomy. However, the ideal method to remove small color...

Aspirin/Folate Prevention of Large Bowel Polyps

This is a randomized controlled trial of aspirin and/or folate supplementation for the prevention of the recurrence of neoplastic polyps (adenomas) of the large bowel.

Computer Assisted Optical Assessment of Small Colorectal Polyps

The aim of the study is to develop a computer program which is able to distinguish between adenomatous and non- adenomatous polyps on the basis of optical features of the polyps. Still ima...

Medical and Biotech [MESH] Definitions

The growth of INTESTINAL POLYPS. Growth processes include neoplastic (ADENOMA and CARCINOMA) and non-neoplastic (hyperplastic, mucosal, inflammatory, and other polyps).

Discrete tissue masses that protrude into the lumen of the COLON. These POLYPS are connected to the wall of the colon either by a stalk, pedunculus, or by a broad base.

Focal accumulations of EDEMA fluid in the NASAL MUCOSA accompanied by HYPERPLASIA of the associated submucosal connective tissue. Polyps may be NEOPLASMS, foci of INFLAMMATION, degenerative lesions, or malformations.

Discrete abnormal tissue masses that protrude into the lumen of the DIGESTIVE TRACT or the RESPIRATORY TRACT. Polyps can be spheroidal, hemispheroidal, or irregular mound-shaped structures attached to the MUCOUS MEMBRANE of the lumen wall either by a stalk, pedunculus, or by a broad base.

A well-differentiated, benign, hamartomatous proliferation of odontogenic epithelium, probably arising from the rests of Malassez.
