What is Subserosal adipose tissue?
What is Subserosal adipose tissue?
Subserosal adipose tissue – This is a layer of fat that sits directly below the muscularis propria. The subserosal adipose tissue is near the outside surface of the colon.
What is Frank carcinoma?
Frank adenocarcinoma: Adenocarcinoma arising from the colon wall (no evidence of a polyp) In Situ: Noninvasive; intraepithelial; (adeno)carcinoma in a polyp or adenoma, noninvasive.
What is colorectal pathology?
When your colon was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. The pathologist sends your doctor a report that gives a diagnosis for each sample taken.
Is adipose tissue cancerous?
Obesity has been linked to the increased risk and aggressiveness of many types of carcinoma. A state of chronic inflammation in adipose tissue (AT), resulting in genotoxic stress, may contribute to carcinogenesis and cancer initiation. Evidence that AT plays a role in cancer aggressiveness is solid and mounting.
Can adipose tissue become cancerous?
Cancer initiation in obesity can be triggered by chronic inflammation in adipose tissue, which creates localized genotoxic stress leading to carcinogenesis. Carcinoma growth is fueled by adipokine signaling from adipose tissue-derived cells, which can infiltrate tumors.
Can they see cancer during colonoscopy?
During colonoscopy, precancerous and cancerous growths throughout the colon can be found and either removed or biopsied. An advantage of having a colonoscopy is that growths in the upper part of the colon, where they would be missed by sigmoidoscopy, can be detected or found.
What is abnormal tissue in the colon?
Adenomas (adenomatous polyps) are abnormal growths attached to the lining of the colon or rectum. Dysplasia describes changes to cells. Mild (low-grade) dysplasia means the cells are slightly abnormal. Severe (high-grade) dysplasia means the cells look very abnormal and more like cancer cells.
What are the three zones of perirectal adipose tissue?
The perirectal adipose tissue was divided into 3 zones: inner (1), middle (2), and outer (3) thirds, respectively. Marker lines indicate pericolonic tumor deposits. Transverse whole mount section of a rectal specimen from the edge of the tumor with exophytic adenomatous part.
What kind of tumor is a pericolonic tumor?
In that model, pericolonic tumor deposits (PTDs) are defined as tumor nodules in the surrounding pericolonic/perirectal adipose tissue outside lymph nodes. 2 Patients with PTDs have an adverse prognosis, and their disease-free survival is significantly lower compared with patients without such deposits.
Which is the best definition of white adipose tissue?
white adipose tissue ( yellow adipose tissue) the adipose tissue composing the bulk of the body fat. Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health, Seventh Edition. © 2003 by Saunders, an imprint of Elsevier, Inc. All rights reserved.
How is shape associated with origin of pericolonic tumor deposits?
Pericolonic tumor deposits (PTDs) are associated with an adverse outcome in colorectal cancer. According to the International Union Against Cancer they are classified as N1 or V1/V2 depending on their shape. This recommendation, however, is not well supported by the literature.
