Polyps and polyposis syndromes of the intestines

Current Diagnostic Pathology, 1997
Polyps of the intestines represent a considerable proportion of the practising pathologist's workload. There are many types of intestinal polyp and accurate histological assessment is imporant to ensure the accurate diagnosis and appropriate management of patients.

NATURE OF JUVENILE POLYPS IN THE LARGE INTESTINE

Acta Pathologica Japonica, 1976
Forty‐five juvenile polyps were found among approximately 390 mucosal polyps of the large Intestine. Various degrees of epithelial pseudostratlflca‐tion were found among juvenile polyps and the larger‐sized polyps of both juvenile type and adult one fended to have a more advanced degree of epithelial pseudostratincation.

Inflammatory Fibroid Polyp of the Small Intestine

JAMA: The Journal of the American Medical Association, 1980
To the Editor.— Inflammatory fibroid polyp of the gastrointestinal tract is a rare benign lesion, usually located in the stomach. To our knowledge, only 24 cases have been described in the ileum. 1 Because of easy confusion with a malignant neoplasm, a correct diagnosis is important.

Exercise and Intestinal Polyp Development in APCMin Mice

Medicine & Science in Sports & Exercise, 2003
Epidemiological evidence suggests that physical activity protects against colon cancer. We previously used a mouse predisposed to intestinal polyps (APCMin) to evaluate this association and found the suggestion of fewer polyps in exercised males but not females.

Surgical treatment of polyps of the large intestine

The American Journal of Surgery, 1948
Abstract Intestinal polyps occur with sufficient frequency to constitute an important surgical problem. Over 50 per cent of polyps occur in the distal bowel within visualization of the sigmoidoscope. Biopsy of these lesions should be used to exclude malignancy. They may be destroyed or removed by fulguration.

Intestinal Polyps and Polyposis Syndromes

2014
Intestinal polyps are abnormal mucosal or submucosal growths that bulge into the lumen of the intestine. Gastrointestinal polyps in children commonly occur in the rectum or colon. Most colon polyps in children are benign. Intestinal polyps occur in children between 1 and 6 years of age, but polyps can occur at any age.

MORPHOLOGY AND HISTOCHEMISTRY OF LARGE INTESTINAL POLYPS

Acta Pathologica Japonica, 1980
In order to assess the progress of the growth of large intestinal polyps into cancer, the epithelial height and the size of the epithelial nuclei were measured. Mucin histochemistry was also carried out. The increase of the histologic grade was based on the extent of epithelial pseudostratification; epithelial height became greater and epithelial ...

Endoscopic polypectomy for the removal of polyps of the small intestine

Gastroenterologia Japonica, 1982
Since intussusception is a common complication of the Peutz-Jeghers polyps, laparotomy should be recommended to remove them. However, all of them will not be palpable or discernible during laparotomy. Operative endoscopy was employed for removing polyps of the small intestine of a 22-year-old female who was previously diagnosed as Peutz-Jeghers ...

The Significance of Papillary Features in Polyps of the Large Intestine

American Journal of Clinical Pathology, 1974
Six hundred sixty-two polypoid lesions of the large intestine were classified as adenomas, papillomas, mixed lesions (adenomatous and papillary features), or hyperplastic polyps. Carcinoma was found in 48% of papillomas, 18% of mixed lesions, and 1% of adenomas.

Genetic conditions associated with intestinal juvenile polyps

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2004
AbstractJuvenile polyps are hamartomatous polyps found primarily in infants and children, and in association with juvenile polyposis (JP; OMIM# 174900), Cowden syndrome (CS; OMIM# 158350), and Bannayan‐Riley‐Ruvalcaba syndrome (BRRS; OMIM# 153480).
