A 31-year-old Balinese male, who has undergone hemodialysis for 9 years and then diagnosed with renal cell carcinoma (RCC). The basis of the diagnosis was from the increased abdominal complaints and left hip pain. The investigation with ultrasound and abdominal CT scan obtained the mass on the left kidney and after the radical nephrectomy surgery, examination of the pathology found multicystic kidney disease with extensive necrosis with malignant markings in some preparations. Kidney tumors rarely occur in patients undergoing long-term hemodialysis. This is allegedly due to the inactivation of a tumor suppressor gene. Therefore, periodic checks are necessary to detect the presence of malignancy in patients undergoing long-term hemodialysis. As these cases are rarely reported in Indonesia and there is often a delay in diagnosis, it is expected to add insight to early diagnosis and provide optimal therapy to prolong patient life expectancy. Early detection and treatment are expected to provide a better prognosis and prolong the patient's life expectancy.
