According to the data, the combined risk of dysplasia/malignancy is about 83% with a 50% risk of dysplasia and overt malignancy in 33% of cases of giant rectal villous adenomas larger than 8 cm.Kasalovi, MladenElek, ZlatanIgrutinovi, Gojko...
Colonoscopy revealed a 1cm solitary rectal polyp, which was completely removed by endoscopic resection. Histologic studies revealed low-grade intraepithelial dysplasia; the stroma of adenoma showed focal localization by highly proliferative lymphoid cells. Immunohistochemical analyses demonstrated that lymphoid ...

(i) Normal colonic mucosa, (ii) hyperplastic polyp, (iii) tubular adenoma with low-grade dysplasia, (iv) tubular adenoma with high-grade dysplasia, (v) transition between low-grade to high-grade dysplasia and carcinoma as well as (vi) carcinoma. Panels (vii–ix) show magnified portions of...
serrated polyplow-grade appendiceal mucinous neoplasm\n KRAS mutationOBJECTIVE. This study aimed to examine the relationship between low-grade appendiceal mucinous neoplasms (LAMNs) and serrated polyps (SPs) of the appendix, both characterized by KRAS mutations and overlapping morphologic features. ...
Nonsteroidal anti-inflammatory drug-induced redifferentiation from high-grade to low-grade dysplasia occurred in all but two patients. Tissue-PGE2 levels were greatly reduced. Unwanted, curable side effects were rare (gastritis, n = 2), and laboratory controls are within detection limits. ...
Histological examination after endoscopic removal showed a low-grade dysplasia in an adenomatous polyp of the esophagus developing on pyloric-type heterotopic gastric mucosa (HGM). Three years later, the patient remains well with no evidence of esophageal disease. We review 25 reported cases of ...
Both were reported histologically to be tubular adenomas with low-grade dysplasia. Histopathological examination of the rectal cancer showed a Dukes' B T3 N0 (0/43 nodes) V1 R0 cancer. The right-sided polyp was a benign tubulovillous adenoma. The patient did not receive adjuvant chemotherapy ...

In sporadic CRC the dysplastic precursor lesion is the adenomatous polyp; a single, discrete focus of neoplasia that is typically managed by endoscopic polypectoray. In patients with long-standing IBD the dysplasia may be polypoid or flat, localized or diffuse, and marks the entire colon as ...
