#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH
Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.

#3076 Endometrial Small Cell Neuroendocrine Carcinoma: Case Report and Literature Review
Introduction: Endometrial small-cell neuroendocrine carcinoma (ESCNEC) is extremely rare. It is characterized by early regional and systemic spread leading to rapid development of lymph nodes, pelvic and extrapelvic metastasis and compromising the outcome.

#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.

#25 Predictors of response to radio-embolization (TheraSphere ®) treatment of neuro-endocrine liver metastasis
Introduction: Neuroendocrine tumors (NET) frequently metastasize to the liver. Most patients have diffuse, and therefore incurable, disease. NET liver metastasis has been shown to respond to yttrium-90 microspheres therapy. This study aims to define factors that predict response to radio-embolization in patients with NET liver metastases.

#125 Ectopic hormone secreting phaeochromocytoma: A francophone observational study
Introduction: Ectopic hormone-secreting phaeochromocytomas are rare and only small reports of 1-2 cases exist in the literature. In the past, this condition has been linked with increased malignancy, familial syndromes and ACTH secretion.

#361 Rats heterozygous for the MENX-associated p27 mutation develop a MEN phenotype
Introduction: MENX is a spontaneous multiple endocrine neoplasia syndrome in the rat showing phenotypic overlap with both MEN1 and MEN2 human syndromes. MENX is caused by a biallelic germline mutation of the Cdkn1b (p27) gene and it was described as recessively inherited. CDKN1B alterations have been also identified in human patients with MEN1-like features but no MEN1 mutations (MEN4).

#545 A Case of ACTH-Secreting Bronchial Carcinoid
Introduction: Ectopic ACTH syndrome (EAS) occurs in about 5-10% of ACTH-dependent hypercortisolism and, in up to 15% of cases, is related to occult neoplasms.

#566 A Case Report of a Patient with Metastatic Cervical Paraganglioma Responding to the Tyrosine Kinase Inhibitor Sunitinib
Introduction: Paragangliomas are rare neuroendocrine neoplasms that arise from neural crest cells, and are associated with increased expression of angiogenic growth factors. There have been isolated case reports describing potential efficacy with Sunitinib, a tyrosine kinase inhibitor.
