Kobara et al reported that endoscopic imaging under direct view has potential diagnostic value for submucosal tumors in the gastrointestinal (GI) tract. The two granular cell tumors in this study were both white, cloudy, round, and elastic, with no visible tumor coating. Final pathological diagnosis was obtained by core biopsy using the submucosal endoscopy with mucosal flap method. [25]
