A 45 year old female with a history of ulcerative colitis presents with vague abdominal pain three years status post total colectomy. An x-ray was performed and reveals a 3.5- cm left upper pole solid renal mass. An ultrasound 3 years prior read both kidneys as 'normal'. Subsequent CT- scan demonstrates that the mass is enhancing and homogenous, suspicious for renal cell carcinoma. Serum creatinine is normal and the patient denies hematuria. A partial nephrectomy is performed. Frozen section evaluation for margin and diagnosis is read as "oncocytic neoplasm, favor oncocytoma; tumor is present within 0.1 cm of the parenchymal resection margin."
