Endoscopic mucosal resection allows to remove superficially growing tumours of the gut by miniinvasive and relatively safe endoscopic approach. During the procedure, the submucosal layer beneath the tumour is infiltrated with diluted epinephrine and subsequently the mucosa with entire tumour is resected using the normal polypectomy snare. The authors present a case report of the patient with esophageal granular cell tumour treated by the mucosectomy. Granular cell tumour is a rare, usually benign disease with malignant course in 2-4% of patients. There are no data in the literature about using the endoscopic mucosal resection in the treatment of esophageal granular cell tumour. The authors consider the mucosectomy to be a treatment of choice in cases of superficially growing granular cell tumours of t he esophagus.
