Abstract
BACKGROUND
Granular cell tumor (GCT) is a rare soft tissue tumor that has malignancy potential. Despite the lack of specific clinical manifestations, GCT has special gastroscopic and endoscopic ultrasonographic manifestations.
CASE SUMMARY
A male patient was admitted because of epigastric pain for 20 d, and there were no positive signs of abdominal examination. Gastroscopy showed that there was a 0.5 cm × 0.7 cm submucous eminence on the right wall of the esophagus at 39 cm from the incisor, and the tumor had a yellowish and smooth surface, and was hard and movable on touch. Endoscopic ultrasonography showed that the lesion was slightly hyperechoic and originated from the submucosa. After endoscopic submucosal dissection, it was confirmed pathologically to be an esophageal GCT.
CONCLUSION
Esophageal GCT is clinically rare and has specific endoscopic and pathological manifestations. Because of the malignancy potential, active endoscopic treatment is necessary. Surgical treatment is still needed for malignant lesions or lesions invading the muscle layer.
