Abstract
BACKGROUND: Mature cystic teratomas (MCTs) are the most common ovarian neoplastic lesions found in adolescents. MCTs are usually asymptomatic and are often discovered incidentally on exam or imaging. The recurrence rate of MCTs following cystectomy is 3-4% and incidence of malignant transformation is estimated to be 0.17-2%. Given the accuracy with which MCTs can be diagnosed preoperatively studies suggest that these lesions can be treated surgically using laparoscopic techniques. The management of MCTs in the adolescent population poses unique challenges given the potential impact on sexual development and fertility. CASE: A 17-year-old female was found to have bilateral adnexal masses consistent in appearance with MCTs on computed tomography after a motor vehicle accident. She underwent exploratory laparotomy with pathology confirming the presence of bilateral ovarian MCTs. Three years later she returned to the office with occasional abdominopelvic pain. Ultrasound revealed bilateral complex cysts suggestive of recurrent MCTs. She was expectantly managed with serial ultrasounds and after 24 months, slow but visible growth of the MCTs was confirmed. The patient is now 22 years old and asymptomatic. What is the most appropriate management? SUMMARY AND CONCLUSION: The risks of expectant management in women like the one presented are small. This suggests that although the traditional treatment for MCTs is laparoscopic ovarian cystectomy, in children and adolescents with MCTs we should consider close follow-up without intervention to preserve ovarian function and future fertility.
