Granular Cell Tumor of the Esophagus: Analysis of five cases with review of four additional cases in Korean literature / 대한소화기내시경학회지

ABSTRACT

Granular cell tumor(GCT) has been identified in all organ systems, most often in the oral cavity and subcutaneous tissue. GCT of the esophagus has been considered rare. However, this neoplasm is being recognized with increased frequency since the use of fiberoptic endoscopy has become widespread. We report 5 cases of granular cell tumors involving the esophagus, all of which were incidentally found. Four additional cases of GCT which appeared in the Korean literature were reviewed.
