The patient was referred to the urology department for a right-sided renal mass (size: 2 cm) detected during routine annual imaging follow-up for a malignant right inguinal fibrous histocytoma and liposarcoma that had been diagnosed 6 and 4 years earlier, respectively.
A routine computed tomography (CT) scan detected a right-sided enhancing mid-pole renal mass measuring 2.3.
Immunohistochemistry revealed carbonic anhydrase 9 (CA9) expression could be helpful for differential diagnosis.
A routine CT scan detected a right-sided enhancing mid-pole renal mass measuring 2.3 cm.
pathology revealed a tumor measuring 1.7 cm × 1.4 cm × 1.0 cm with a capsule abutting, leading to a diagnosis of a grade 2 ccpRCC without necrosis and a final pathologic stage of T1aN × M0.
The patient underwent open right-sided partial nephrectomy.
Patients who have previously been treated with tumor need careful follow-up.
