A Case Report of Largest Documented Multilocular Cystic Nephroma Removed by Thoracoabdominal Approach.

Large renal tumours are not uncommon in developing countries. Enhancing renal tumours are considered to be malignant unless proved otherwise and radical surgical resection remains the mainstay of treatment of such tumours. A giant renal tumour, especially on right side, poses a big challenge for the operating team and requires a thoracoabdominal approach for successful excision. We report successful removal of the largest documented Multilocular Cystic Nephroma (MLCN, 5.5 kg) from a 28-year-old female who presented with right abdomen lump since two years. The surgery was done through a 9th intercostal thoracoabdominal incision as the mass (31 x 19 x 19.6 cm) extended from right sub-diaphragmatic space up to the dome of the bladder. We discuss here the technique of removing such a huge renal mass and the challenges an operating surgeon may encounter.
