Area of Science:

  • Endocrinology
  • Oncology
  • Nephrology

Background:

  • Pheochromocytoma, a rare neuroendocrine tumor, typically arises in the adrenal medulla.
  • Ectopic pheochromocytomas located outside the adrenal glands are uncommon, posing diagnostic challenges.
  • Hypertension is a hallmark symptom, often presenting as paroxysmal or sustained elevations in blood pressure.

Observation:

  • A 47-year-old female farmer presented with a three-year history of severe, episodic hypertension.
  • Initial investigations revealed mild hyperglycemia and fluctuating vanillylmandelic acid levels.
  • Imaging identified an extra-adrenal tumor near the pancreas, compressing major abdominal vessels.

Findings:

  • Histopathological analysis confirmed a paraganglioma with pheochromocytoma characteristics.
  • Surgical resection of the 80 mm tumor was successfully performed after medical stabilization.
  • Post-operative follow-up showed complete resolution of hypertension and hyperglycemia without medication.

Implications:

  • This case underscores the importance of considering ectopic pheochromocytoma in patients with refractory hypertension and abdominal masses.
  • Early diagnosis and surgical management are crucial for favorable outcomes.
  • Highlighting the potential for complete cure, even with large, ectopic tumors.
