#4446 Uncommon ophthalmic presentation of a small bowel neuroendocrine tumour: Case report

Introduction: Neuroendocrine tumours (NETs), including carcinoid tumours, are slow-growing neoplasms commonly originating in the gastrointestinal tract or bronchus, but they can also arise in other sites. Due to their indolent nature, the majority of NETs are diagnosed at an advanced stage, typically to the lymph nodes, liver, or bones.

#3893 Pancreatic neuroendocrine tumor associated hypophosphatemia due to tumor-induced osteomalacia – A case report

Introduction: Tumor-induced osteomalacia (TIO) is a rare syndrome characterised by hypophosphataemia and osteomalacia with renal phosphate wasting caused by elevated levels of fibroblast growth factor 23 (FGF23) in the setting of tumor. The primary tumor is typically found in bone or soft tissue.

#3734 Treatment outcomes in patients with localized and advanced glucagonomas – A case series

Introduction: Glucagonomas are rare functional pancreatic neuroendocrine tumors, which are often metastatic at diagnosis. Due to their low prevalence, the effectiveness of available treatment modalities remains unclear.

#3677 Myelophthisis as an end-stage outcome of rare metastases in neuroendocrine tumors – A dual case report

Introduction: Intra-abdominal Neuroendocrine Tumors (NETs) usually metastasize to regional lymph nodes, liver, and bone. Myelophthisis (MPT) is the destruction of the medullary microenvironment due to the tumoral invasion of the trabecular space, altering normal hematopoiesis; it’s frequently caused by metastasis of breast, prostate, and lung adenocarcinomas, and neuroblastoma. MPT due to NET is an unrecognized phenomenon with few cases reported, almost exclusively in poorly differentiated NETs.

#3243 The major impact of proGRP monitoring in advanced atypical lung carcinoid: A case report

Introduction: Atypical lung carcinoids (aLC) are more aggressive than typical carcinoids, metastasizing more commonly to distant sites, and require vigilant follow-up. However, the surveillance is often hampered by the non-informative Chromogranin A (CgA) levels.
