A Case of Esophageal Granular Cell Tumor Which Treated by 'O'-Type Band Ligation and Polypectomy / 대한소화기내시경학회지

ABSTRACT

Granular cell tumors involving the esophagus are rare tumors. Since Abrikossoff first reported five cases of granular tumor of the tongue in 1926, fewer than 200 cases of esophageal granular cell tumors have been reported in the world. The granular cell tumors usually were seen in tongue, skin & breast. it has rarely been noted in the esophagus. The treatment of this tumor was not established well. Therefore, we report a case of granular cell tumor of the low esophagus, which was resected by polypectomy following 'O'-band ligation. This 56-year-old male patient was transferred to our hospital because of abnormal endoscopic finding on the esophagus at local clinic. There was esophageal polypoid lesion on the low esophagus. After polypectomy, the lesion was revealed as granular cell tumor in histopathologic examination.
