#89 Hyperplasia-adenoma sequence in pituitary carcinogenesis: new insight into the role of AIP gene
Introduction: Pituitary adenoma predisposition has been recently associated with germline mutations in the Aryl-Hydrocarbon Receptor Interacting Protein (AIP) gene. This association has been detected in familial and, more rarely, in sporadic cases. The mechanisms by which the AIP mutations promote pituitary adenoma development remain unknown.

#2156 Two Cases Synchronous Atypical Parathyroid Adenomas and Papillary Thyroid Carcinoma
Introduction: A literature review revealed a prevalence of approximately 3% of nonmedullary thyroid cancer, which was found in patients operated on for primary hyperparathyroidism (pHPT). Papillary thyroid carcinomas(PTC) is a malignant epithelial tumour. PTC represent up to 87% of all thyroid carcinomas. Atypical parathyroid adenoma(APA) are a subset of parathyroid neoplasms that exhibit some of the features of parathyroid carcinoma but lack unequivocal invasive growth. APA represents about 0,5-4% of cases of pHPT. As a group, they may be considered tumors of uncertain malignant potential.

#930 Distinct Expression of Splicing Variants of the Human MEN1 (Multiple Endocrine Neoplasia Type 1) Gene in Various Pituitary Adenomas
Introduction: MEN1 is an autosomal-dominant tumor syndrome characterized by the occurrence of tumors in multiple endocrine tissues, including parathyroid, enteropancreatic neuroendocrine and anterior pituitary. The MEN1 gene consists of 10 exons transcribed into a 610 a.a. protein. It was reported that heterogeneity of human MEN1 gene transcripts related to variation in their 5’ UTR. Six distinct exsons1 (e1A-e1F) were isolated using RNA from thymus, pancreas and kidney.

#975 Electron Microscopy of Pancreatic Beta Cell Neuroendocrine Tumors (NETs) in Multiple Endocrine Neoplasia Type 1 (MEN1) Knockout Mice Reveal an Adenomatous Phenotype with Depletion of Insulin Granules and Increased Mitochondrial Content
Introduction: Insulinomas are β cell neuroendocrine tumors (NETs) that secrete insulin, and ~4% of insulinoma patients have multiple endocrine neoplasia type 1 (MEN1). One in ten MEN1 patients present with an insulinoma. Previous reports describe insulinomas as possibly having typical granules (46.4%) or atypical smaller granules (34.3%), both associated with adenomas, or agranular cells (14.3%) associated with carcinomas. MEN1 knockout (Men1+/-) mice develop pancreatic NETs that are mostly insulinomas, and their ultrastructural phenotype is unknown. We hypothesized that these may resemble the adenoma phenotype with atypical granules.
