#3006 Teratoma with Malignant Transformation: A Case Report of a Neuroendocrine Tumor That Arises from the Bronchial Mucosa in a Mature Cystic Teratoma
Introduction: Mature cystic teratoma (MCT) is the most common type of germ cell tumor in the ovary. A malignant tumor that arises in a pre-existing mature teratoma is called teratoma with malignant transformation (TMT).

#546 Treatment of Malignant Neuroendocrine Tumors of the Hepatopancreatododenal Region
Introduction: The incidence of malignant NETs of the hepatopancreatoduodenal region is currently set at 10-15 cases per 100,000 people. Patient treatment and prognosis differ from those with adenocarcinoma.

#21 Peptide Receptor Radioligand Therapy (PRRT) is an Effective Treatment for the Long-Term Stabilization of Malignant Gastrinomas
Introduction: Gastrinomas represent a rare group of neuroendocrine tumors usually located in the duodenum or pancreas. They secrete gastrin, which is responsible for the clinical picture of severe acid-related peptic disease and diarrhea, known as the Zollinger-Ellison syndrome (ZES). While symptomatic control may be achieved with proton-pump inhibitors (PPIs) and somatostatin analogues (SSAs) treatment, little data is known regarding the possible anti-tumor effect of the peptide receptor radioligand therapy (PRRT) in gastrinoma patients.

#1890 Natural History of Type 1 Gastric Carcinoid (gNENs) and Risk of Adenoma/Adenocarcinoma in Endoscopic Surveillance Programme
Introduction: Patients with gNENs & autoimmune gastritis are exposed to 2 malignant risks: 1)transformation of gNENs, felt to be low & guidelines advocate either resection of all lesions or selective endoscopic mucosal resection(EMR) of larger lesions; 2)ill-defined risk of gastric adenoma/adenocarcinoma.

#431 Everolimus Controlled Resistant Hypoglycemia in Malignant Insulinoma
Introduction: A pancreatic neuroendocrine carcinoma with liver metastases was diagnosed on July 2006 in a 65-year-old man. He was treated with octreotide LAR 30 mg for three years. At liver progression he was enrolled in a multicenter Italian trial titled “XELBEVOCT” with Bevacizumab + Metronomic Capecitabine + Octreotide LAR 30 mg. After seven months, the patient exhibited severe hypoglycemic syndrome with HGT serum levels<30 mg/dl, insulin 150 microUI/ml, and C-peptide at upper normal limits. Endocrinologist prescribed prednisone, diazoxide and recombinant glucagon for hypoglicemic crisis, with little benefit. In March 2010, the patient was given radio-labelled Lu-177-OCTREOTATE treatment. After three cycles, hypoglicemic symptoms were still uncontrolled. CT scan showed stable disease.

#884 Simultanenous Duplicate Malignant Disease-Adenocarcinoma of the Colon and Disseminated Neuroendocrine Tumor
Introduction: Fifty-nine-year old man, under examination due to weight loss, enterorrhagia, general abdominal discomfort. Endoscopy detected tumorous infiltration 20 cm from the anus, bleeding. Histology: adenocarcinoma. CT abdomen detected liver lesion. The lesion was hypervascularized, and the CT picture was atypical for metastatic adenocarcinoma. CT chest: tumor lesion in the left lower segment, metastatic LN in mediastinum. According to the CT, the picture is atypical for metastases.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#1838 A Rare Case of Ectopic Cushing's Syndrome
Introduction: Cushing's syndrome has an incidence of 0.7 - 2.4 per million people per year. In 15% of cases, it’s associated with non-pituitary tumors secreting ACTH. Pheochromocytoma accounts for 5% of ectopic ACTH secretion.
