#4651 Neuroendocrine hyperplasia of infancy (NEHI) vs. diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH): What is the difference?

Introduction: Neuroendocrine Hyperplasia of Infancy (NEHI) is a rare disease that belongs to the group of interstitial lung disease in children; characterised by hypoxemia, tachypnoea, and respiratory distress, often misdiagnosed as reactive airway disease or bronchiolitis. The diagnosis relies on histologic evaluation. We describe the clinical presentation and paraclinical characteristics of paediatric patients with NEHI.

#4322 Clinical outcomes of patients with rectal neuroendocrine tumours smaller than 10mm after endoscopic resection

Introduction: Rectal neuroendocrine tumours (r-NETs) generally have a good prognosis, but up to 20% may be misdiagnosed during endoscopy, risking inadequate treatment. Prognosis factors include tumour size, grading, staging, and lymphovascular invasion, with guidelines recommending endoscopic resection for small, low-grade lesions.

#3870 Small bowel neuroendocrine tumor with carcinoid heart disease

Introduction: Patients with neuroendocrine tumors are often misdiagnosed, at least for the first stage of the disease. In fact, carcinoid syndrome is the clinical expression of the vasoactive substances produce. Carcinoid heart disease is a hazardous and irreversible complication especially in late identified cases.

#3434 Retrospective study on 515 cases misdiagnosed as neuroendocrine neoplasms from a pathologic consultation center

Introduction: Recent progress in the diagnosis and classification of Neuroendocrine Neoplasms (NENs) is achieved. However, the histological morphology and immunohistochemistry of NENs overlap with other lesions, and the differential diagnosis in clinical practice faces many challenges.
