#4563 Clinical case of a young woman with acromegaly, hyperprolactinemia and pituitary tumour with mixed morphology of adenoma and gangliocytoma

Introduction: Acromegaly is a rare disorder that develops due to persistent hypersecretion of somatotropic hormone in adults after closure of the growth plates. In the majority of cases, the cause is a pituitary adenoma.

#4550 The relationship between MEN1 germline mutations and SSTR2 expression in neuroendocrine tumours

Introduction: Multiple endocrine neoplasia type 1 (MEN1) is a rare hereditary disease characterised by the development of multiglandular parathyroid disease, pituitary tumours, and duodenopancreatic neuroendocrine tumours (NETs). Germline mutations in the tumour suppressor gene MEN1 are the underlying cause. Somatostatin receptor 2 (SSTR2) is commonly expressed by NETs. However, the expression of SSTR2 in patients with MEN1 remains unclear.

#4491 Expression and clinical significance of IGFBP-3 in pituitary neuroendocrine tumours

Introduction: IGFBP-3 is a regulatory factor highly expressed in pituitary neuroendocrine tumours that may provide reference for the clinical diagnosis and treatment of pituitary neuroendocrine tumours.

#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.
