[Extra-adrenal pheochromocytoma discovered peroperatively].

Area of Science:

• Endocrinology
• Surgical Oncology
• Pathology

Background:

• Ectopic pheochromocytoma is a rare tumor arising outside the adrenal glands.
• This case presents an asymptomatic variant, posing diagnostic challenges.

Observation:

• Radiological imaging revealed a right retroperitoneal mass without renal involvement.
• Intraoperative tachycardia during tumor removal necessitated rapid resection.
• Post-resection bradycardia and cardiac arrest occurred, despite resuscitation efforts.

Findings:

• Histological examination confirmed ectopic pheochromocytoma.
• The patient experienced severe hemodynamic instability during and after surgery.
• Despite successful resuscitation from cardiac arrest, the patient demised postoperatively.

Implications:

• This case underscores the critical importance of vigilant hemodynamic monitoring during ectopic pheochromocytoma resection.
• It highlights the potential for severe, life-threatening complications even in asymptomatic cases.
• Accurate diagnosis and tailored surgical strategies are crucial for improving outcomes in ectopic pheochromocytoma.
