A 48-year-old man presented to our surgical oncology division with incidentally detected abdominal mass. On examination, a ballotable swelling was present in the right lumbar region. His imaging studies showed a large multicystic mass in the lower pole of the right kidney. With radiological diagnosis of cystic renal cell carcinoma (RCC), the patient was taken up for surgery. Histopathology showed tubulocystic RCC (TC-RCC) with a focus of papillary RCC. Though closely related to papillary RCC, TC-RCCs of kidney are a distinct group of RCC. Analysis of more cases is required to understand the exact tumor biology and to ascertain prognosis.
