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.

Clinical features and management of paragangliomas in a tertiary university hospital
Introduction:
Paragangliomas (PG) are rare neuroendocrine tumors that arise from the extra-adrenal paraganglia. The most frequent location is head and neck PG (HNPG), usually non-functioning tumors. PG present a high rate of genetic susceptibility mainly associated with SDHx mutation. Clinical presentation depends upon catecholamine secretion and tumor location. Surgery remains the standard treatment, although radiotherapy and systemic therapies can be considered for unresectable or metastatic disease.

More than Rare Pheochromocytomas: Bilateral and Hemorrhagic, Giant and Metastatic
Introduction:
Pheochromocytomas (PCC) are rare neuroendocrine tumors. These catecholamine-secreting tumors, with an average size of 4.9cm, are multiple in 10% of cases. About 10% are malignant but distant metastases are rare. Non-traumatic adrenal hemorrhage is an unusual potentially fatal event seen in PCC.
