Mucosectomía endoscópica de un tumor de Abrikosoff esofágico

The definitive diagnosis is histological. The origin of GCT is neurogenic and the tumor is composed of eosinophilic granular cytoplasm and PAS-positive cells, which show the S-100 protein on immunohistochemistry. Although GCT is usually clinically and histologically benign, some malignant cases have been reported. Consensus is lacking on the treatment and follow-up of this tumor. Currently, endoscopic mucosal resection is a safe and effective technique to treat submucosal esophageal lesions, allowing subsequent histologic analysis. We present three patients with esophageal CGT, who were definitively treated with endoscopic mucosal resection.
