Core Tip

Core tip: Gastric adenocarcinoma showing features of a submucosal tumor is unusual. Preoperative diagnosis is difficult due to the generally deep location of the tumor and non-specific and overlapping features on imaging studies. In this case, esophagogastroduodenoscopy revealed a 1.6 cm type 0-Is lesion covered by congested mucosa on the gastric angle. Endoscopic ultrasound and computed tomography reveal no swollen lymph nodes and the usual biopsy cannot give a definite diagnosis. After endoscopic submucosal dissection and gastrectomy with lymph node dissection, this patient was diagnosed with GC (Bormann type I, T1bN2M0).
