Core Tip

Core tip: Herein is described rare case of small undifferentiated intramucosal early gastric cancer (EGC) < 20 mm in size with lymph-node (LN) metastasis. It has been reported recently that small undifferentiated intramucosal EGC < 20 mm in size without lymphovascular involvement or ulcerative findings had virtually no risk of LN metastasis. Therefore, such small undifferentiated EGCs have become candidates for endoscopic resection. It was within this context we experienced the present case involving a small undifferentiated intramucosal EGC < 20 mm in size without lymphovascular involvement or ulcerative findings that evidenced LN metastasis.
