Chromophobe cell renal carcinoma with acquired cystic disease of the kidney in a long-term hemodialysis patient

We report a rare case of chromophobe cell renal carcinoma found in a 52-year-old female who had received hemodialysis therapy for 13 years. She was diagnosed as having a left renal tumor 7.5 cm in diameter with acquired cystic disease of the kidney (ACDK) by ultrasonographic examination during periodical systemic screening. As abdominal computed tomography scanning and enhanced color Doppler ultrasonography suspected that the hypervascular tumor was renal cell carcinoma, she underwent translumbar nephrectomy in July 2000. The histopathological diagnosis was chromophobe cell carcinoma with pT2 and grade 2 malignancy. Chromophobe cell carcinoma is uncommon among renal tumors with ACDK found in long-term hemodialysis patients.
