Mutations in the mitochondrial succinate dehydrogenase (SDH) subunits A, B, C, and D have been shown to hamper oxidative phosphorylation and predispose to pheochromocytomas (PHEOs) and paragangliomas (PGLs). These tumors are characterized by a glycolytic and pseudohypoxic phenotype, which is also seen in most PHEOs/PGLs occurring as part of von Hippel–Lindau (VHL) syndrome, due to VHL gene mutations. The rate of extra-adrenal tumor origin and malignancy however is particu...

Background: It is well established that life-long follow-up is required for patients with hereditary pheochromocytomas and paragangliomas (PPGLs), due to the potential of developing recurrent disease. However, whether follow-up of patients with sporadic PPGLs is necessary, remains unclear.Aims: To examine the prevalence and predictors of recurrent disease in patients with sporadic PPGLs.Materials and method: This multicenter study included retrospective ...
