#3090 Retrospective Experience with Pherochromocytoma (PH) and Paraganglioma (PG) in a Single Argentinian Institution

Introduction: Pherochromocytoma (PH) and paraganglioma (PG) are neuroendocrine tumors arising in cromaffin cells in the adrenal medulla or extra adrenal paraganglia respectively. Clinical presentation is diverse. All PG/PH have malignant potential. Hereditary cases comprise up to 40% of all PG/PH.

#3084 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH): A Case Report and Review of Literature

Introduction: Majority of euroendocrine tumorsare found in the gastrointestinal tract and bronchopulmonary. Multifocal disease is common among patients with low-grade NET. One example of this is diffuse idiopathic pulmonary neuroendocrine cell hyperplasia. DIPNECH is an extremely rare but indolent disease with predilection for nonsmoking, middle-aged women.

#3072 Rb and p53 Status Determination by Immunochemistry Is Complementary in Routine Practice to Genetic Testing of Neuroendocrine Neoplasms

Introduction: Rb and p53 status may help distinguishing well from poorly differentiated neuroendocrine neoplasms (NEN) and may predict response to chemotherapy. Studies correlating Rb/p53 genetic and immunohistochemistry were performed on high-quality frozen samples with high throughput techniques efficient for copy number determination. This situation differs from routine practice in which small deletions may be hard to detect on formalin-fixed paraffin-embedded (FFPE) samples with a gene panel approach.
