en 24696796 Background: Ovarian fibroma is the most common benign solid tumor of the ovary, which is often difficult to diagnose preoperatively. The choice treatment for ovarian fibroma is surgical removal, but discussions for the operative approach, laparoscopic or open, in the literature seem to be scant. Case Presentation: We presented a unique clinical experience of laparoscopic approach to a case of 15 cm unilateral ovarian fibroma in a 24 year old patient, with a successful and complete resection of the tumor beside ovarian tissue preservation in December 2012 in Rasoul-e-Akram hospital, Tehran, Iran. Conclusion: In conclusion, we should not forget the role of laparoscopy as a diagnostic procedure even in suspicious cases of ovarian fibroma with solid tumor, ascites, and pleural effusion.
