title: [Laparoscopic resection of retroperitoneal tumors: report of two cases].
abstract: Here we report two rare cases of retroperitoneal tumors which were found incidentally and resected laparoscopically. Case 1; A 43-year-old woman presented with general fatigue and revealed liver dysfunction. Although the initial diagnosis with computed tomography (CT) was left non-functioning adrenal tumor, it was proven as a retroperitoneal tumor adjacent to the left adrenal gland by laparoscopic examination. The tumor was resected laparoscopically and diagnosed histopathologically as a solitary retroperitoneal neurofibroma. Case 2; A 68-year-old man was being followed for a renal stone and a perirenal tumor was found by CT. It was resected laparoscopically and diagnosed as a mature retroperitoneal teratoma by histopathological examination. We conclude that laparoscopic resection is useful for the retroperitoneal tumors as well as for adrenal tumors.
