Background: Ovarian leiomyoma is very rare and constitutes 0.5%-1% of ovarian benign masses. Although most adnexal masses are benign, primary purpose of the assessment is to eliminate any malignancies. The most important issue in the evaluation of ovarian masses is to differentiate between malignant and benign masses. Laparoscopy is an important diagnostic and minimally invasive method for these purposes.
Case Presentation: In this paper, we present a case report on laparoscopic evaluation of a patient who was diagnosed with right ovarian spontaneous parasitic myoma and who did not have a history of uterine surgery.
Conclusion: Uterine ovarian myoma is extremely rare and can be confused with malignant ovarian masses. Laparoscopy option should be considered as the primary approach in the management of masses with suspicious location and appearance and in the differentiation of benign and malignant.
