#946 Immunohistochemical Staining of Catecholamine-Synthesizing Enzymes in Head and Neck Paraganglioma Tissue

Introduction: Head and neck paragangliomas (HNPGLs) are non-producing neuroendocrine tumors, alhough 19-28% of patients have an increased dopamine production. The high sensitivity of 18F-DOPA PET also shows that these tumors might be able to synthesize catecholamines.

#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.
