Clinical and histological features of benign esophageal tumors in endoscopic biopsy specimens in Booali Sina Hospital, Qazvin (2004-2013)

Abstract

The aim of this retrospective study was to determine the clinical and histological features of benign esophageal tumors in endoscopic biopsy specimens in Booali Sina Hospital, Qazvin from 2004 to 2013. Data were analyzed using Chi-square test and ANOVA. Eighteen tumor lesions were found in 11 men and seven women with mean age of 63±15.3 years old. Of 18 cases, seven were glycogenic acanthosis, five were squamous papilloma, two were each type of leiomyoma, two were adenomatous polyp, and two were hyperplastic polyp. The frequency of tumor lesions was 0.06% among endoscopic examinations, 3.6% among esophageal biopsies and 5.7% among benign esophageal lesions. The distal third (61.1%) and the middle third (27.8%) of the esophagus were the most frequent sites of involvement. The association of endoscopic appearance, site of involvement, sex, and age with histological types was not significant.
