Granular Cell Myoblastoma of the Esophagus Incidence and Surgical Treatment

Abstract

Granular cell myoblastoma (Abrikossoff's tumor), although certainly a rare, almost always benign lesion, is being encountered with increasing frequency in areas of particular interest to the otolaryngologist or surgeon in the upper aerodigestive tract. Although such lesions have been found frequently in the oral cavity and larynx, only one case has been reported of such a lesion originating in the esophagus. The detailed clinical and pathologic findings of three additional patients with esophageal lesions are described. Conservative surgical removal of granular cell myoblastoma may be preferable to endoscopic dilatation.
