Most common presenting symptom was dysphagia in both groups 327 (32.4%) followed by vomiting (22.8%) and weight loss 196 (19.4%). The Esophagogastroduodenoscopy (EGD) findings showed the distal esophagus involvement in most of the patients (36.3%) in both groups. CT scan findings showed that the lower region was the most involved region in 367 (36.4%) patients, followed by middle and upper in 227 (22.5%) and 156 (15.5%) patients respectively. The thickening of mass on CT- scan was circumferential in most of the patients (42.7%) in both groups.
