Purpose of Investigation: The present study reviewed and analyzed a case of LPD, including the medical history, diagnostic process, and treatment strategy, and it will improve our understanding of the disease. Material and Methods: A 25-year-old female was referred to the present gynaecology unit for abdominal pain. A following up investigation was conducted until a gynecological ultrasound revealed a myoma in the lower abdomen. Then surgery was conducted to remove the myoma. Results: The ultrasound revealed a mass in the left ovary. Furthermore, the patient was diagnosed with ovarian tumor pedicle torsion and was hospitalized. During the laparoscopic surgery, a 10×7.0-cm myoma in the left posterior uterine wall which was removed using a morcellator was identified. The post-operative pathology report determined that the uterus was rich in leiomyoma cells and bleeding. Conclusion: As a rare benign tumor, LPD is commonly seen in female of reproductive years, but its pathogenesis has not been identified. Lack of specific clinical manifestations and signs, LPD is difficult in the preoperative diagnosis.
