#246 SDHB Loss Predicts Malignancy in Pheochromocytomas/Sympathethic Paragangliomas, but Not Through Hypoxia Signalling

Introduction: To date there is no reliable histopathological marker of malignancy for pheochromocytomas/sympathetic paragangliomas (PCC/PGL). It is well-known that PCC/PGL in the hereditary context of an SDHB germline mutation very often metastasize. The immunohistochemical loss of SDHB expression was recently shown to be a surrogate marker for the presence of an SDH germline mutation in PCC/PGL. SDHB loss is supposed to be tumorigenic via activation of hypoxia signals.
