Abstract

Background: Pheochromocytoma and renal cell carcinoma (RCC) are both rare tumors, and their concurrent diagnosis in a single individual is exceptionally uncommon.
Case presentation: A 50-year-old male was unexpectedly diagnosed with a right adrenal mass and a left renal mass while being evaluated for urinary symptoms. The adrenal mass was identified as pheochromocytoma through elevated catecholamine levels and imaging results, whereas the renal mass raised significant suspicion for RCC.
Results: The patient was stabilized preoperatively using alpha and beta blockers to address catecholamine excess before undergoing laparoscopic adrenalectomy. Surgical considerations for the renal mass were complex due to its anatomical location, prompting a meticulous choice between partial and radical nephrectomy.
Conclusion: This case emphasizes the critical need for comprehensive diagnostic assessments, collaborative planning across disciplines, and tailored management strategies when confronting dual pathologies. Further investigation is essential to enhance treatment approaches for patients facing rare coexisting conditions such as pheochromocytoma and RCC.
