[Perirenal myxoliposarcoma. Case report with laparoscopic approach].
OBJECTIVE
To report our experience in the management of one case of perirenal myxoliposarcoma.


METHODS
We report the case of an 86-year-old male consulting for occasional dizziness. Examination revealed a left flank abdominal mass. CT scan reported the presence of a 12 cm multiloculated cystic mass at the lower pole of the right kidney Hand-assisted right laparoscopic nephrectomy was carried out.


RESULTS
The operation was uneventful and the pathologic study reported a kidney with preserved architecture and a tumor showing characteristics of grade 1-2 myxoliposarcoma with undifferentiation to grade 3 myxofibrosarcoma in intimate contact with the lower pole.


CONCLUSIONS
We believe that laparoscopic surgery permits the surgical solution of this type of lesion without compromising the oncological principles, and offers the well-known advantages of a minimally invasive approach.
