A primary clear cell adenocarcinoma of the colon is a rare oncologic entity. We herein report a case of such a tumor of the sigmoid colon in a 71-year-old woman who was successfully treated by an endoscopic polypectomy in our hospital. We also reviewed the published reports regarding cases of primary clear cell tumors in the colon.

AIMTo assess the clinical characteristics of patients with complicated erosive esophagitis (EE) and their associated *** prospective, cross-sectional study included patients diagnosed with EE by upper gastrointestinal endoscopy between October 2014 and March 2015 at 106 Japanese hospitals. Data on medical history, general condition, gastrointestinal symptoms, lifestyle habits, comorbidities, and endoscopic findings were collected using a standard form to create a dedicated database. Logistic regression analysis was used to calculate adjusted odds ratios (aOR) and 95%CI for the association with complicated *** the study period, 1749 patients diagnosed with EE, 38.3% of whom were prescribed proton pump inhibitors (PPIs) were included. Of them, 143 (8.2%) had EE complications. Esophageal bleeding occurred in 84 (4.8%) patients, esophageal strictures in 45 (2.6%) patients, and 14 (0.8%) patients experienced both. Multivariate analysis showed that increased age (aOR: 1.05; 95%CI: 1.03-1.08), concomitant use of psychotropic agents (aOR: 6.51; 95%CI: 3.01-13.61), and Los Angeles grades B (aOR: 2.69; 95%CI: 1.48-4.96), C (aOR: 15.38; 95%CI: 8.62-28.37), and D (aOR: 71.49; 95%CI: 37.47-142.01) were significantly associated with complications, whereas alcohol consumption 2-4 d/wk was negatively associated (aOR: 0.23; 95%CI: 0.06-0.61). Analyzing associated factors with each EE complication separately showed esophageal ulcer bleeding were associated with increased age (aOR: 1.05; 95%CI: 1.02-1.07) and Los Angeles grades B (aOR: 3.60; 95%CI: 1.52-8.50), C (aOR: 27.61; 95%CI: 12.34-61.80), and D (aOR: 119.09; 95%CI: 51.15-277.29), while esophageal strictures were associated with increased age (aOR: 1.07; 95%CI: 1.04-1.10), gastroesophageal reflux symptom (aOR: 2.51; 95%CI: 1.39-4.51), concomitant use of psychotropic agents (aOR: 11.79; 95%CI: 5.06-27.48), Los Angeles grades C (aOR: 7.35; 95%CI: 3.32-16.25), and D (aOR: 20.34; 95%CI: 8.36-49.53) and l
