Current views on paediatric phaeochromocytoma and paraganglioma with a focus on newest guidelines

Phaeochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumours which arise from chromaffin cells of the adrenal medulla or extra-adrenal autonomic ganglia. PPGL most commonly present in adulthood but can arise in childhood and adolescence with an estimated annual incidence of 0.5 cases per million children per year. There have been significant advances in the diagnosis and management of PPGL over the past 2-3 decades based largely on the study of adult patients. These advances in clinical knowledge can be applied to paediatric patients but like other cancers, paediatric PPGL must be viewed as a distinct subset with their own specific challenges and opportunities for improved clinical care. This review article provides an overview on the diagnosis and management of PPGL in children focusing on recent international guidance.
