#4471 Acromegaly and small intestinal neuroendocrine tumours: Association or coincidence?

Introduction: Neuroendocrine tumours of the small intestine (SI-NETs), although rare, are the most prevalent primary neoplasms of this organ. Acromegaly is characterised by excessive secretion of growth hormone (GH), typically due to a pituitary adenoma, but in rare cases, it can result from ectopic secretion of GH-releasing hormone (GHRH) by non-pituitary tumours, particularly NETs of the lung or pancreas.

#3071 Hormonal Ectopic Secretion Syndromes Associated to Neuroendocine Neoplasia

Introduction: Neuroendocrine neoplasias (NEN) are able to produce and secrete bioactive peptides and cause distinct syndromes related to their biological effects. The outcome will depend on the oncological disease as well as the hormonal syndrome

#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.

#1426 Pseudotumor of Thymus Occuring After Hypercortisolism Recovery: Case Report

Introduction: Cushing syndrome is due to an ectopic secreting adrenocorticotropic hormone (ACTH) in 10 % to 20% of cases. Among them, thymic tumors represent almost half of cases. It has been described that patients sometimes develop benign hyperplasia after hypercortisolism correction.
