The Largest Cystic Nephroma Treated by Laparoscopic Nephron-sparing Surgery: A Case Report and Review of the Literature

Cystic nephroma is a rare benign tumour of the kidney. The symptoms are often non-specific and the diagnosis of the disease is usually made incidentally. Definitive diagnosis can be possible with histopathological evaluation. Surgical resection provides curative treatment. We report a successful removal of cystic nephroma in a 67-year-old female which was managed by laparoscopic nephron-sparing surgery. When a renal mass including multiple cystic formations is visualized on radiological imaging, the clinician should consider cystic nephroma for differential diagnosis, and these cases should be evaluated in terms of nephron-sparing surgery.
