食道に発生したGranular cell tumorの一例

抄録

A 45 years old male with Granular cell tumor of the esophagus had been follwed up endoscopically for one year. This patient had no clinical feature, when this tumor was found incidentally. By X-ray studies, a clearly limited shadow defect was found at lower esophagus. Esophagoscopy revealed that there was a small sessile, white tumoroon the anterior wall at 35 cm. from the (incisor teeth) with somewhat depressed area at the top of the tumor, however no ulceration nor erosion was found on the surface of the tumor. Pathologic diagnosis of the endoscopic biopsy specimen was granular cell tumor. Although further upper GI series and esophagoscopy were performed after one year, no changes were noted in size and shape of this tumor. This may be the first clinical 'report of an esophgeal granular cell tumor in Japan.
