Submucosal tumor-like lesion originating from colon tuberculosis: a case report and review of the literature.

A 76-year-old male had a solitary submucosal tumor-like lesion in the sigmoid colon originating from tuberculosis. The lesion, up to 1 cm in diameter, was found incidentally during a routine colonoscopy, which revealed a protuberant submucosal growth with a shallow depression of the overlying mucosa in the center of the tumor. Histologically, the endoscopic biopsy revealed caseating granulomas and infiltration of Langhans giant cells and epithelioid cells, consistent with tuberculosis, were also observed.

Characteristics of small bowel tumors detected by double balloon endoscopy.

Background: A few reports suggest that the emergence of double balloon endoscopy (DBE) has likely changed the clinical picture of small bowel tumors (SBTs).

Aim: To further clarify the characteristics of SBTs detected by DBE.

Methods: A retrospective chart review was conducted in 227 patients who had undergone DBE.

The presence of large serrated polyps increases risk for colorectal cancer.

Background & Aims: There is evidence that serrated polyps (serrated adenomas and hyperplastic polyps) have different malignant potential than traditional adenomas. We used a colonoscopy database to determine the association between the presence of serrated colorectal polyps and colorectal neoplasia.

Methods: We performed a multicenter observational study of 10,199 subjects who underwent first-time colonoscopies.
