Core Tip

Core tip: Mixed serous-neuroendocrine neoplasm (MSNN). MSNNs are a mixed tumor containing two components with different pathologies, namely pancreatic serous cystic neoplasm (PSCN) and pancreatic neuroendocrine tumor (PanNET). For MSNNs, diffuse PSCN involving the whole pancreas is extremely rare with only eight previous case reports. Here, we report a novel case of diffuse PSCN admixture with an isolated PanNET in a Chinese woman, and also review the previous literature. Due to its close relationship with Von Hippel-Lindau syndrome, and the malignant potential of neuroendocrine component, patients with MSNN should undergo thorough systemic examinations, including molecular genetic analysis, and close clinical follow-up is also recommended.
