Notes

Pheochromocytoma is a catecholamine-secreting neuroendocrine tumor of adrenal medullary origin; extra-adrenal counterparts (paragangliomas) arise from sympathetic / parasympathetic ganglia (head/neck, thoracic, abdominal). They are biologically and clinically a single spectrum (PPGL); this entity is anchored to the adrenal subset for ICD-10 cleanliness but cross-references SDHx-driven extra-adrenal paragangliomas in prevention workstream notes. Hereditary fraction is the highest known among adult cancers (~30–40%). NCCN and Endocrine Society recommend germline panel testing (RET, VHL, SDHB/C/D/AF2, NF1, TMEM127, MAX, FH) for ALL patients with PPGL — not restricted by family history. This makes PPGL a sentinel disease for hereditary cancer surveillance pathways (RET → MEN2 prophylactic thyroidectomy; VHL → multi-organ surveillance; SDHB → lifetime PPGL + RCC surveillance). Classical clinical triad: headache + palpitations + sweating; many patients present with paroxysmal or sustained hypertension. Biochemical diagnosis: plasma free metanephrines or 24-h urinary fractionated metanephrines (preferred over catecholamines). Functional imaging (MIBG, Ga-68 DOTATATE PET) for staging and...
