BACKGROUND: @entity1821 are the second most frequent @entity5 in the retroperitoneal space and classically present as a large mass with minimal symptoms and a high local recurrence rate. The gold standard of treatment remains surgical excision. CASE REPORT: We describe the first successful removal of a well-differentiated @entity27418 using a laparoscopic approach. An asymptomatic @entity1 presented a large fatty mass in the retroperitoneal space on CT imaging. A transperitoneal laparoscopic approach was planned. A well-capsulated mass was exposed under Gerota's fascia that was dissected easily and removed completely without complications. Histologic examination revealed a well-differentiated @entity1821 . No recurrence was found at 12 months' followup. CONCLUSION: Resecting the mass completely remains the most important predictor of local recurrence and overall survival in @entity1821 . Thus, the success of radical surgical treatment is very important. The laparoscopic approach is technically safe and successful in maintaining oncologic principles and avoiding recurrences in @entity27418 , representing a feasible alternative to open surgery.

Case report: Laparoscopic removal of 10-cm XXXX .
