Abstract
Granular cell tumors are rare but benign submucosal tumors of the esophagus. Usually tumors are rather small and do not cause symptoms. We demonstrate a case with typical macroscopic appearance at endoscopy and endosonography. Important differential diagnoses are leiomyoma, and gastrointestinal stroma tumors. Although the patient had no symptoms, he insisted on a complete removal of this tumor. After careful inspection of the submucosal tumor with high-definition white light endoscopy and endosonography we performed endoscopic resection. No post-procedural complications were observed.
