Two cases of adrenal pheochromocytoma associated with renal cell carcinoma are reported. The first case was in a 56-year-old woman who had been treated for hypertension. Computerized tomography (CT) scan revealed a right renal tumor and a right adrenal mass. ⋯ Right radical nephrectomy and left adrenalectomy were performed, followed by corticosteroid supplementation. In both cases, histopathological diagnosis was renal cell carcinoma and adrenal pheochromocytoma. Both patients had no clinical evidence for von Hippel-Lindau disease such as tumorous lesions of the central nervous system, spinal cord and retina, and cystic lesions of the kidney and pancreas.
