Abstract

Herein, a rare case of port site metastasis, following a laparoscopic radical nephrectomy in a 62-years old male patient with a stage pT2N0M0 and Fuhrman grade III renal cell carcinoma, is reported. The patient suffered port site metastasis, with local recurrence. The port site metastasis was incidentally found in the patient during the laparoscopic examination for a laparoscopic mass resection of a local recurrent tumor. The most important appropriate surgical techniques are those where the port site metastasis can be controlled.

  Fig. 2 Abdominal computed tomography, with intravenous contrast, showing a small solid mass in the retroperitoneum. The image was taken twenty four months after the laparoscopic radical nephrectomy for the primary tumor.

  Fig. 3 A laparoscopy showing an incidentally found small sized tumor. The tumor was under the 4th port site scar of a previous laparoscopic radical nephrectomy.

  Fig. 4 Microscopic findings of the resected port site tumor. Hematoxylin-eosin staining of the port site tumor specimen showing ametastatic tumor with suture granuloma (A: original magnification, ×20, B: original magnification, ×100), and vimentin immunohistochemical staining is positive (C: original magnification, ×200), confirming the diagnosis of a Fuhrman grade III, conventional type, metastatic renal cell carcinoma.
