Regression of Paraneoplastic Optic Neuropathy Associated with Glucagonoma After Surgical Resection Abstract #1108

Introduction: Glucagonomas-associated ocular manifestations have been exceptionally reported.
Aim(s): To report the case of a patient with a glucagonoma associated with paraneoplastic optic neuropathy (PON) and to review literature.
Materials and methods: A 65-year-old man presented with bilateral visual loss and central scotoma. Later, the occurrence of diarrhoea, necrolytic migratory erythema evocated a glucagonoma syndrome, which was advocated by elevated chromogranin A and glucagon levels. CT scan showed a pancreatic tumor, which was confirmed to be a well-differentiated neuroendocrine tumor at pathological examination of biopsies. Surgical resection was performed and led to the dramatic improvement of bilateral visual acuity, and complete resolution of scotomas. Hence, the retained diagnosis was a pancreatic glucagonoma associated with a PON.

#2191 Endocrine Paraneoplastic Syndromes in Patients with Neuroendocrine Neoplasms
Introduction: Endocrine paraneoplastic syndromes (ePNS) result from production of bioactive substances from tumours not related to their expected tissue of origin. Neuroendocrine neoplasms (NENs) have been associated with ectopic secretion of several hormones, but the prevalence of ePNS has only been described in a small number of studies.

#2145 Thrombotic Risk in Gastroenteropancreatic Neuroendocrine Tumors: A Single Centre Experience
Introduction: Neuroendocrine neoplasms (NENs) comprise a heterogeneous group of neoplasms associated with paraneoplastic syndromes. Venous thromboembolism (VTE) is a frequent complication in neoplastic patients and it is associated with increased morbidity and mortality. To date, there have been no specific studies in NEN, except for glucagon-secreting tumors
