Abstrakt:	Introduction: Pheochromocytomas are rare catecholamine-secreting tumors with a high potential for recurrence post-surgery, necessitating prolonged follow-up. This case highlights the diagnostic and therapeutic challenges in managing recurrent pheochromocytoma. Case Presentation: A 25-year-old female, with a history of left pheochromocytoma treated with adrenalectomy a decade earlier, presented with a right adrenal mass. Despite controlled hypertension, elevated urine metanephrines suggested recurrence. Imaging showed a right adrenal mass and suspicious left paraaortic lymph nodes, confirming the diagnosis of recurrent malignant pheochromocytoma in the left adrenal bed and right adrenal gland, with metastasis to the paraaortic lymph nodes. The patient underwent right adrenalectomy coupled with cytoreductive surgery (CRS) in the form of excision of left-sided adrenal bed recurrence and left paraaortic lymph node dissection, intraoperative radiation therapy (IORT), and hyperthermic intraperitoneal chemotherapy (HIPEC). On follow-up six years later, the patient remains free from recurrence. Discussion: This case illustrates the importance of continued surveillance in pheochromocytoma patients, even those with a low-risk profile. The recurrence in this case, despite a smaller initial tumor size and no genetic predispositions, underscores the unpredictable nature of pheochromocytomas. The successful management with CRS, IORT, and HIPEC emphasizes the need for a personalized and multifaceted treatment approach. Conclusion: Pheochromocytoma patients, including those initially considered low risk, require long-term monitoring due to the risk of recurrence. The utilization of CRS, IORT, and HIPEC in this case was pivotal in managing the recurrent and metastatic malignant disease effectively, demonstrating the significance of a comprehensive, multidisciplinary treatment strategy in such complex cases.
