Laparoscopic nephron-sparing surgery for metanephric adenoma.

A 47-year-old patient presented with hematuria of 3-month duration. Computed tomography revealed right lower polar exophytic mass. Laparoscopic nephron-sparing surgery was performed. The macroscopic examination of the mass showed encapsulated tumor with soft pultaceous material. Histologic examination of the mass was consistent with metanephric adenoma. We are reporting this case of metanephric adenoma, being treated with laparoscopic partial nephrectomy.
