Pheochromocytoma

Dental riskcritical

Pheochromocytoma/paraganglioma (PPGL) are catecholamine-secreting tumors causing paroxysmal or sustained severe hypertension, tachyarrhythmias, headache, sweating, and palpitations. Catecholamine surges can lead to hypertensive crisis — especially with stress, pain, or adrenergic drugs. Dental relevance: (1) EPINEPHRINE/VASOCONSTRICTORS ARE CONTRAINDICATED in untreated/suspected PPGL, (2) stress and pain trigger catecholamine release → crisis risk, (3) labile hemodynamics make sedation/anesthesia high-stakes, and (4) beta-blocker before alpha-blocker = dangerous (unopposed alpha → crisis).

The full condition entry includes

  • Safe vs avoid lists: antibiotics, analgesics, local anesthetics
  • Vasoconstrictor limits and treatment modifications
  • Pre/intra/post-op monitoring and deferral criteria
  • Emergency management, explained for study
