#428 Clinical Manifestations of Patients with Pancreatic ß Cells Hyperplasia
Introduction: Pathologic hyperplasia of pancreatic endocrine cells is uncommon. ß cell hyperplasia contributes to persistent hyperinsulinemic hypoglycemia. The manifestations of patients with pancreatic ß cells hyperplasia are variable and their preop. diagnosis is difficult.

#140 Serotonin expression in gastric neuroendocrine tumors and in foci of endocrine cell hyperplasia
Introduction: The most abundant neuroendocrine (NE) cell population of the human oxyntic mucosa is the enterochromaffin-like (ECL) cells, followed by ghrelin, somatostatin and serotonin cells, respectively. All types of ECL cell carcinoids (ECL-CCs) contain serotonin cells but in a varying frequency. Hitherto, only foci of ECL and ghrelin cell hyperplasia have been described in the peritumorous mucosa of types I and II ECL-CCs. It is established that hypergastrinaemia can cause ECL cell hyperplasia but it does not affect serotonin cells. The vesicular monoamine transporter 2 (VMAT 2) is used as an immunohistochemical marker for ECL cells.

#830 The Predictive Value of Gastrin Levels for the Diagnosis of Gastric Enterochromaffin-like Cells Hyperplasia, in Patients with Hashimoto’s Thyroiditis
Introduction: Gastrin and chromogranin A (CgA) levels have been tested for the diagnosis of enterochromaffin-like cell hyperplasia (ECLH), in patients with type 1 diabetes and autoimmune atrophic gastritis but there are no data for patients with Hashimoto's thyroiditis (HT).

#2002 Pulmonary Function Test Physiology and Progression in Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia
Introduction: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare condition characterised by a generalised proliferation of pulmonary neuroendocrine cells within the respiratory epithelium. Little is known of its affects on pulmonary function both at the time of diagnosis and prospectively.

#2246 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH): Characterisation of Prevalence and Prognosis in the Pulmonary Carcinoid Population
Introduction: DIPNECH is considered a rare condition and the natural history is poorly described. It is thought to give rise to pulmonary carcinoids (PCs) (>5mm) or tumourlets (≤5mm).

#30 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia
Introduction: Normal adult lungs contain scattered pulmonary neuroendocrine cells (PNEC). Reactive PNEC hyperplasia is commonly observed in persons who live at high altitude, in cigarette smokers, and in numerous lung diseases. Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) is a rare entity in which PNEC hyperplasia appears without predisposing conditions. According to the 1999 WHO lung tumor classification, DIPNECH is thought to be primarily a neuroendocrine proliferative process, which can be associated with carcinoid tumors and with a clinical picture of constrictive obliterative bronchiolitis. To date, available data regarding the treatment and the prognosis of this rare condition is limited.

#436 Role of Somatostatin Analogues in the Management of Merkel Cell Carcinoma: A Case Report
Introduction: Merkel cell carcinoma (MCC) is a relatively rare neuroendocrine malignant tumor that is characterized by an aggressive course with regional nodal involvement, distant metastases and a high rate of recurrence.

#691 Pancreatic Focal Alpha Cell Hyperplasia with Hyperglucagonaemia without the Glucagonoma Syndrome
Introduction: Pancreatic alpha cell hyperplasia and hyperglucagonaemia without the glucagonoma syndrome is a rare clinical syndrome not widely recognised. Here we describe a novel mutation in the glucagon receptor gene (GCGR) in a patient with the disease.

#924 Somatostatin Analogs (SSA) in Patients with Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia: A Case Series
Introduction: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare lung disease associated with proliferation of neuroendocrine cells in the lung. Although typically considered a benign condition, DIPNECH causes chronic, progressive cough and dyspnea. There have been no treatments described in the literature.
