We reported an interesting case supporting the carcinogenesis of mechanical stimulation of the esophagus, which was compressed by right aortic arch in the long period.
The patient was 52-year-old male, whose chief complaint was retrosternal permeating feeling, under went esophagography, and was pointed out the compression in upper thoracic esophagus. By the esophagoscopy, the upper esophagus 24cm from the incisor, were compressed strongly and pulsated, and 0-IIa+IIb superficial carcinoma was detected on the wall. In the endoscopic ultrasonography, the depth of the cancer was mostly mm, but partially sm.
The thoracotomy revealed that esophagus was compressed by aortic arch and ductus arteriosus ligament. In the resected specimen, cancer invaded to the muscularis mucosa without lymphnode metastasis. Protrusion of the mucosa like this case is suggested to be high risk of malignancy, and should be examined carefully.
