title: Strip biopsy to treat esophageal granular cell tumor.
abstract: Esophageal granular cell tumors are rare neoplasms. We successfully treated a 35-year-old Japanese man with an esophageal granular cell tumor without any complications using strip biopsy. Endoscopic ultrasonography revealed a hypoechoic tumor with a diameter of 8 mm that was confined to the submucosal layer. A strip biopsy done with a two-channel endoscope completely resected the tumor. Six months later, no abnormal findings were recognized in the resected area. Therefore we propose that strip biopsy be considered as a viable alternative treatment for esophageal granular cell tumor, depending on the histologic character, tumor size, and depth of tumor infiltration.
