Port site and local recurrence of incidental solitary renal plasmacytoma after retroperitoneoscopic radical nephrectomy.

Port site and local recurrences are rather rare, especially after laparoscopic excision of renal malignancies. In addition to the known risk factors, including inappropriate surgical technique and specimen removal, the tumor biology is important. Renal plasmacytomas are rare manifestations of plasma cell tumors. We report a case of port site and local tumor recurrence of a solitary renal plasmacytoma after retroperitoneoscopic radical nephrectomy without any known risk factors, other than the aggressive tumor biology itself.
