We report the case of a 46-year-old male with no previous medical background. He complained of abdominal rightsided flank pain, spreading to ipsilateral flank, thermal hikes, hematuria, and positive giordano. The ultrasound found a 5 x 5 cm mass located in right kidney upper pole, which did not compromised renal capsule and presented a fresh bruise, suggesting a malignant tumor. Radical nephrectomy was satisfactory performed; sending the whole kidney to pathology and the patient was discharged within 72 hours. The histopathologic report concluded a conventional clear cell renal cell carcinoma tumor (5.5 x 4.8 cm) Fuhrman grade II, limited to the renal parenchyma. We concluded that the best treatment for this type of cancer is the radical nephrectomy even though you lose a part of the renal function. Radical nephrectomy guarantees the extraction of the whole tumor and avoids dissemination, one of the most common complications.
