GISTs are rare neoplasms that account for less than 1% of all gastrointestinal malignancies. GISTs have the capability to become malignant and then metastasize, whereas leiomyomas are almost invariably benign. In clinical practice, preoperative differentiation between GISTs and leiomyomas is usually difficult, even if EUS-guided fine-needle aspiration or trucut biopsy is performed. Leiomyomas are rare in the stomach and duodenum while GIST are more frequent in the stomach. This patient presented with a 6cm submucosal tumor below the gastroesophageal junction. This video demonstrates the stepwise laparoscopic approach taking into consideration the potentially (pre-)malignant nature of the tumor.
