*These cases were reported before 2010, so it is difficult to apply the new WHO classification (2010). Although our case is NET G2, NET G2 was well-differentiated adenocarcinoma in the previous WHO classification (2000). We listed our tumor as malignant according to the previous diagnosis to check with other cases.
