Mature teratoma during pregnancy: A case report

Abstract

Introduction: The mature teratoma or dermoid cyst of the ovary is a benign tumor with a good prognosis which constitutes less than 1% of ovarian tumors. Its association with pregnancy is rare. Case Report: We report the case of a 30-year-old woman admitted for acute pelvic pain with an abdomino-pelvic mass diagnosed on pelvic ultrasound supplemented by pelvic magnetic resonance imaging (MRI). The indication for surgical exploration was given because of her presentation with pain raising, the size of the mass, and the risk of torsion. The patient underwent conservative treatment based on a cystectomy with multiple biopsies, the anatomical-pathological result of which was in favor of a mature ovarian teratoma. Through the analysis of this observation and the data of the literature, we will discuss the different aspects of this association. Conclusion: Mature teratoma and pregnancy are still a rare entity. Expectant management is appropriate in asymptomatic small mature teratoma. However in symptomatic or large mature teratoma surgical intervention is needed.
