Clinical characteristics and outcomes of SDHB-related pheochromocytoma and paraganglioma in children and adolescents.

Purpose: Pheochromocytomas/paragangliomas (PHEOs/PGLs) are rare in children with only a few SDHB mutation-related cases. Previous studies on children were conducted in small cohorts. This large set of pediatric patients provides robust data in the evaluation of clinical outcomes.
