Esophageal squamous papilloma Esophageal squamous papilloma as an endoscopic finding in the cmdlt gastroenterology service, january 2020- october 2022

Abstract

Introduction: Esophageal squamous papilloma (SPE) is a rare benign epithelial lesion, characterized by warty and whitish projections, generally asymptomatic, visualized incidentally under conventional endoscopy. Worldwide, a prevalence of between 0.07% and 0.45% is estimated. Objective: To characterize the Esophageal Squamous Papilloma as an endoscopic finding in the Gastroenterology Service of the CMDLT. Material and Methods: An observational, descriptive, analytical, cross-sectional and retrospective study was carried out; A sample of 14 patients in whom the presence of esophageal squamous papilloma was detected was selected. Results: The predominant sex was male 71.4%, the average age was 49.76 ± 14.80 years, in terms of location the proximal third represented 71.4%, with respect to color and consistency no relevance was observed. statistics, with 78.57% the indication for endoscopic study was Abdominal Pain 78.57%, 3 patients (3/14; 21.43%) were positive for p16 by IHC, All patients (14/14; 100% ) diagnosed with SEP presented as an endoscopic finding: elevated, exophytic lesion, irregular edges and a vascular pattern with elongated and tortuous vessels. Conclusions: There is a statistically significant association at 5% between the presence of PEE and the location (p<0.001), and a statistically significant association at 10% with the sex of the patients (p=0.081). ). No statistically significant association was found between the presence of PEE and the color of the lesion. The determination of P16 through techniques is not a specific marker for HPV, however it suggests that it may be a serotype of high malignancy.
