Neuroendocrine tumors (NETs) of the extrahepatic bile duct are extremely rare and reported infrequently in the literature. These tumors are difficult to diagnose preoperatively, and the prognosis is variable, often determined by extent of disease, tumor grade and resectability. This case report presents a 45-year-old male with history of biliary obstruction relieved by endobiliary stents with c...

Although the liver is the most common site of metastatic disease from a variety of tumor types, isolated hepatic metastases most commonly occur from colorectal cancer and, less frequently, from neuroendocrine tumors, gastrointestinal sarcoma, ocular melanoma, and others. Complete evaluation of the extent of metastatic disease, both intrahepatically and extrahepatically, is important before cons...

A 50 years old woman with history of pancreatic neuroendocrine tumor diagnosed 2 years ago, which has not been surgically removed,was referred to our department for a 99mTc-Octreotate in order to evaluate the somatostatin receptor status. She was treated with regular sandostatin injections and chemotherapy. Her CT scan which was previously performed confirmed lung, adrenal and hepati...

Liver transplantation has been performed for a wide variety of rare hepatic tumors. The anecdotal nature of this experience makes evidence-based decisions regarding suitability for transplantation very challenging. The largest reports of transplantation for tumors other than hepatocellular carcinoma and cholangiocarcinoma have been for neuroendocrine tumors. Hepatic metastases are present in ap...

Gastroenteropancreatic neuroendocrine tumors (GEP NET) represent heterogenous group of very rare neoplasms. Nevertheless, these tumors have been increasingly diagnosed recently. Authors present own experience with surgical treatment of gastrointestinal neuroendocrine tumors. the aim of the study was to analyse retrospectively own material of patients with gastrointestinal neuroendocrine tumors ...

is an absence of the classical imaging findings consistent with liver metastases, because of the histological pattern of microinvasion3. The massive sinusoidal infiltration and hepatic vessels obstruction by tumor cells result in ischemia and hypoxic hepatocellular necrosis1,3. We have a short window for investigation since most of these patients die soon after admission4. The diagnosis is freq...
