A CASE REPORT OF A ESOPHAGEAL GRANULAR CELL TUMOR REMOVED BY BIOPSY FORCEPS ENDOSCOPICALLY

Abstract

This is a case report of a small granular cell tumor on the middle esophagus removed by biopsy forceps during upper gastrointestinal endoscopy. We performed upper gastrointestinal examination on a 42-year-old male who complained of epigastralgia and during the endoscopy we incidentally found an elevated lesion of Yamada's type 1 sized 3 mm in diameter at 30 cm from the incisors. The lesion was diagnosed as a granular cell tumor by biopsy. Repeated endoscopy showed no elevated lesion any more and rebiopsy confirmed nonexistence of the tumor. Therefore, we suspected the tumor had been removed by biopsy forceps on the first endoscopic examination. The granular cell tumor of the esophagus is uncommon and experiences of endoscopic diagnosis of the granular cell tumor as small as in our report has been rarely reported.
