Abstract

Mucoepidermoid carcinoma is a malignant tumor that occurs mainly in the salivary glands of adults and children, but rarely in the esophagus. A surgical resection is the primary treatment for mucoepidermal carcinoma, and the prognosis has been reported to be poor. A 61-year-old man was diagnosed with an esophageal nodule in upper gastrointestinal endoscopy for the purpose of a medical examination without any special symptoms and an endoscopic resection was performed for an accurate diagnosis. An endoscopic mucosal resection was performed using a band ligation for a complete resection and continuous follow-up with no evidence of recurrence or metastasis. The unknown prognosis of endoscopic resection makes it necessary to follow the patient carefully.

  Fig. 1 (A, B) Esophagogastroduodenoscopy showing a 6-7 mm sized esophageal nodule 31 cm from the upper incisor. The surface of the nodule was flat and the consistency was firm. (C, D) Standard endoscopic variceal ligation was used to aspirate the target lesion and apply a band around it. After removing the banding device, a separate snare was used to resect the lesion with an endoscopic mucosal resection.
