[A case of late perirenal fat recurrence after partial nephrectomy for T1A renal cell carcinoma].
An 84-year-old man had undergone laparoscopic partial nephrectomy for right renal cell carcinoma (RCC), cT1aN0M0 in 2003. The histopathological diagnosis was clear cell carcinoma, grade 1, v (-), surgical margin negative, pT1a. Nine years and 10 months postoperatively, computed tomography scans demonstrated tumors on right renal fossa. As we could not detect other metastatic lesions, we diagnosed him with local recurrence of RCC and planned the surgery with curative intent. He underwent laparoscopic resection of retroperitoneal tumors. The histopathological diagnosis was clear cell carcinoma, grade 2 ＞ 3, v (-), surgical margin negative, and confirmed recurrence of RCC. In retrospective review of 176 cases of pT1a renal cell carcinoma with partial nephrectomy in our institute, 3 patients (1.7%) developed local recurrence and 2 patients (1.1%) developed late local recurrence.
