#4120 Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH): An international case series

Introduction: Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) is a rare disorder that is characterized by diffuse hyperplasia of bronchiolar and bronchial pulmonary neuroendocrine cells. The precise incidence and prevalence is unknown and the clinical course is not fully understood.

#4058 Carcinoid syndrome caused by pulmonary neuroendocrine tumor liver metastases: A case report

Introduction: Neuroendocrine tumors (NETs) comprise a heterogeneous groups of maliganancies that arise from neuroencrine cells throughout the body and most commonly originate from the small intestine, lung,and rectum. Pulmonary NETs originate from pulmonary neuroendocrine cells that occur as individual cells or small pulmonary neuroendocrine cell. Although carcinoid tumors are considered low or intermediate-grade tumors, they metastasize to regional lymph nodes and distant organs, and the most common sites metastases are the liver and bone.

#3074 Medullary Thyroid Carcinoma and DIPNECH: An Unexpected Association

Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumour of the C-cells of thyroid gland. Diffuse idiopathic pulmonary neuroendocrine cells hyperplasia (DIPNECH) is a rare condition, thought to be primarily a neuroendocrine proliferative process which can develop into carcinoid tumours.

#3049 Organoid Models of Neuroendocrine Cell Growth and Tumorigenesis

Introduction: A paucity of in vitro and in vivo models has limited the study of Neuroendocrine neoplasms (NENs). Moreover, little is known about normal neuroendocrine (NE) cells and how they contribute to NEN formation.

#2754 Somatostatin Analogs (SSA) in Patients with Symptomatic Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH)

Introduction: DIPNECH is characterized by a proliferation of pulmonary neuroendocrine cells and multifocal neuroendocrine tumorlets and/or tumors. Although usually indolent, DIPNECH can cause chronic cough and dyspnea. There is very limited information on treatment.
