Activity Summary

Required reading for all learners: Implicit Bias impacts patient outcomes

Pheochromocytoma multisystem crisis (PMC) is a distinct and potentially lethal complication of pheochromocytoma. Patients in PMC present with severe hemodynamic instability and an array of end-organ failures (including heart, lung, liver, and kidney), hyperthermia (≥ 40 °C), and encephalopathy. Even more rare than the tumor itself, PMC occurs in only 7% to 18% of patients with a pheochromocytoma.


  • Identify the signs and symptoms of a pheochromocytoma and the difference between a pheochromocytoma and pheochromocytoma multisystem crisis
  • Describe the hindrances to early diagnosis of pheochromocytomas and the potentially lethal consequences of a delayed diagnosis.
  • Describe the different adrenergic receptors and their impact on the body.
