Summary
Extensive pheochromocytomatosis, a rare condition, was successfully treated with cytoreductive surgery. Lifelong biochemical surveillance is crucial for patients with this adrenal tumor disorder.
Area of Science:
- Endocrinology
- Surgical Oncology
- Genetics
Background:
- Recurrent symptoms of pheochromocytoma (palpitations, anxiety, diaphoresis) occurred 9 years post-adrenalectomy.
- Biochemical tests showed elevated metanephrines, and imaging revealed widespread intra-abdominal tumor deposits and a liver lesion.
- Genetic testing was negative for common pathogenic variants associated with pheochromocytoma.
