The characteristic appearance of pancreatic neuroendorcine tumours (pNETs) on ultrasound is that of a hypoechoic lesion with a hyperechoic halo around it.
B-mode EUS showed that all metastatic lesions to the pancreas and PNET were hypoechoic with homogenous-echo pattern and regular margins.
Primitive neuroectodermal tumors (PNETs), which are known as Ewing's sarcoma (ES), are high-grade malignant neoplasms that develop from a group of neuroectodermal small round cells' (1)'.
Histologic investigation of adrenal and pancreas specimens confirmed the diagnosis of PCC and PNET (World Health Organisation grade 3) respectively.
Petersen, "Pancreatic neuro-endocrine tumors (PNETs): incidence, prognosis and recent trend toward improved survival," Annals of Oncology, vol.
Unlike other pNET, such as gastrinoma or somatostatinoma, insulinomas are usually benign, so it is possible to speculate that this peculiar behavior could be attributed to particular oncogenic events.
In the context of an updated WHO pathology classification system, we sought to examine potential differences in patients with ES versus PNET histology using the largest dataset available.
Ewing sarcoma and PNET are aggressive round cell tumors and considered as two morphologic variants of the same entity (EPS) because they show similar clinical, immunohistochemical, and molecular profiles [7].
Following sarcoma, transformation to adenocarcinoma and primitive neuroectodermal tumor (PNET) are the next most common histologies [6].

The remaining malignancies were colon cancer, pancreatic cancer, peritoneal mesothelioma, peritoneal adenocarcinoma, primitive neuroectodermal tumor (PNET), extragonadal sex cord tumor with annular tubules (SCTAT), and cancer of unknown primary.
