Resumen
Abstract Background and study aims Recent advances in endoscopic equipment and diagnostic techniques have improved the detection of dysplasia in the inflamed mucosa of patients with ulcerative colitis (UC). However, it remains difficult to endoscopically identify flat-type dysplasia which has been formerly recognized as invisible dysplasia. Patients and methods In this retrospective, single-center study, we endoscopically identified 10 cases of flat-type-predominant dysplasia by targeted biopsy among 38 intramucosal dysplasia lesions from patients with UC who underwent surgical or endoscopic r

Resumen
Abstract Adenocarcinoma and dysplasias are recognized complications of Barrett mucosa. In the past, the treatment for this carcinoma was esophagectomy. However, new techniques, including endoscopic mucosal resection, sometimes replace esophagectomy and are becoming standard procedures in clinical practice, not just in major medical centers. Pathologists must learn to handle these specimens, which have extensive artifacts. Also, Barrett mucosa has duplicated stromal layers beneath the mucosa that include a new lamina propria and a new muscularis mucosae. We must be aware of these peculiarities

Resumen
Barrett’s Esophagus is a common condition associated with chronic gastroesophageal reflux disease. It is well known that it has an association with a higher incidence of esophageal adenocarcinoma, but this neoplastic transformation is first preceded by the onset of low and high-grade dysplasia. The evaluation of low grade dysplastic esophageal mucosa is still controversial; although endoscopic surveillance is preferred, several minimally invasive endoscopic therapeutic approaches are available. Endoscopic mucosal resection and radiofrequency ablation are the most used endoscopic treatments for

Background. Endoscopic surveillance for early detection of dysplastic or neoplastic changes in patients with Barrett's esophagus (BE) depends usually on biopsy. The diagnostic and therapeutic role of endoscopic mucosal resection (EMR) in BE is rapidly growing. Objective. The aim of this study was to check the accuracy of biopsy for precise histopathologic diagnosis of dysplasia and neoplasia, compared to EMR in patients having BE and related superficial esophageal lesions.

Glottal dysplasia is likely the most common laryngeal disease with a discernible lesion; however, investigations describing its initial anatomic geographic presentation are rare. To examine this, we identified 52 patients who did not have significant prior treatment or glottal cancer. Thirty-one patients had bilateral disease, so there were 83 vocal folds with precancerous dysplasia. The phonatory mucosa was the dominant disease site in all; the epicenter was on the superior surface in 65 of the 83 folds and on the medial surface in 18 of the 83 folds.

Resumen
Abstract Background and study aims Accurate endoscopic detection of dysplasia in patients with Barrett’s esophagus (BE) remains a major clinical challenge. The current standard is to take multiple biopsies under endoscopic image guidance, but this leaves the majority of the tissue unsampled, leading to significant risk of missing dysplasia. Furthermore, determining whether there is submucosal invasion is essential for proper staging. Hence, there is a clinical need for a rapid in vivo wide-field imaging method to identify dysplasia in BE, with the capability of imaging beyond the mucosal layer

Background: Ulcerative colitis(UC) is a chronic inflammatory disease of the colon associated with increased cancer risk of colitis associated cancer(CAC). Keratins(K) are intermediate filament(IF) proteins, and are key component of the cellular cytoskeleton. K8 null mice develop colitis; a subset of IBD patients have mutation in K8 gene. Keratins play a role in cell-death signalling pathways; epithelial cells lacking K8 and K18 are more sensitive to TNF-mediated apoptosis.

Abstract Oral potentially malignant diseases (OPMDs) are a group of oral mucosal lesions that have a higher chance of turning into cancer. They show up in different ways, have different causes, and look differently on a microscopic level. To date, there are no clinical or histological factors that could predict the OPMDs’ malignant transformation to oral squamous cell carcinoma (OSCC), except for previous OSCC and WHO classification. Early diagnosis appears to be essential in these lesions in order to identify the risk of malignant progression and treat them accordingly. The standard treatment

Cancer of the colon is the second leading cause of cancer related death in North America and Europe. Colonoscopy is currently the gold standard for the detection and removal of polyps and the diagnosis of cancer. Although a field of intense research, there are currently no surrogate serum or stool markers that accurately identify patients at risk who may have adenomatous colon polyps or curable cancer. Clinicians therefore rely on white light colonoscopy to survey colonic mucosa in their search for polyps. White light endoscopy has some limitations. It cannot detect flat, non-raised lesions. I
