ABSTRACT
Abrikosoffs tumor (AT), or granular cell tumor (GCT), isrelatively rare in the gastrointestinal tract, where the mostcommon site is the esophagus. This tumor is usually foundincidentally when an upper gastrointestinal endoscopy is carriedout for another reason. Endoscopically, GCT appearsas a small, yellow and submucosal lesion covered by normalmucosa. Endoscopic ultrasonography shows a homogeneoushypoechoic lesion with well defined margins.The definitive diagnosis is histological. The origin of GCT isneurogenic and the tumor is composed of eosinophilic granularcytoplasm and PAS-positive cells, which show the S-100 protein on immunohistochemistry. Although GCT isusually clinically and histologically benign, some malignantcases have been reported. Consensus is lacking on the treatmentand follow-up of this tumor. Currently, endoscopicmucosal resection is a safe and effective technique to treatsubmucosal esophageal lesions, allowing subsequent histologicanalysis. We present three patients with esophagealCGT, who were definitively treated with endoscopic mucosal resection (AU)
