#4567 Malignant pheochromocytoma with late distant metastases and secondary hypercalcaemia

Introduction: Pheochromocytoma is a rare neuroendocrine tumour of the adrenal medulla. Malignant variants occur with a very low frequency and can be diagnosed only after the spread of distant metastasis.

#4124 Evaluating a possible association between promoter methylation level of genes encoding catecholamine metabolizing enzymes and metanephrine secretion in pheochromocytoma and paraganglioma

Introduction: Paragangliomas (PPGLs) are rare neuroendocrine tumors that may secrete catecholamines and their metabolites (metanephrines [MN], normetanephrine [NMN]). Secretion patterns differ by adrenal/extra-adrenal origin and genetic alteration. Catecholamines synthesis is carried by phenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH), aromaticL-aminoacid decarboxylase (AADC), dopamine β-hydroxylase (DBH) and phenylethanolamine N-methyltransferase (PNMT). However, their regulation in PPGL is not entirely understood.

#1414 Non-functioning Adrenal Composite Pheochromocytoma-Ganglioneuroma Simultaneous with Subclinical Cushing's Syndrome Due to Contralateral Adrenal Hyperplasia - An Unusual Presentation

Introduction: “Composite” pheochromocytoma is a rare tumor, consisting of pheochromocytoma and neuroblastic tumors. The definite diagnosis is histological. Subclinical Cushing's syndrome refers to autonomous glucocorticoid production without specific signs and symptoms of Cushing's syndrome.
