Introduction: Uterine tumors resembling ovarian sex cord tumors (UTROSCT) belongs to a rare group of uterine neoplasms. Although, a limited number of malignant and/or recurrent cases have been reported, UTROSCT is generally described as a tumor with benign behaviour. Since the reported cases of UTROSCT are limited and biologic pattern of the tumor has not been clearly elucidated, there is no consensus in the management of the patients. There are only few cases who have undergone fertility sparing surgery and proceeded with successful pregnancies. The objective of the present report is to review the literature relevant to the case presented herein who was first conservatively managed by laparoscopic UTROSCT resection; then consecutively achieved a spontaneous pregnancy and experienced recurrence which was managed by laparoscopic hysterectomy and bilateral salpingectomy.
Materials and Methods: PubMed was searched with the keyword ‘’Uterine tumors resembling ovarian sex cord tumors’’ from 1976 to 2018. We have found 62 related articles out of 116; from which 128 relevant cases of UTROSCT were analysed.
Results: Among the reported 128 cases, 11.7% of them were conservatively treated initially. Conservative management has been subsequently followed with 5 live births, including our case, whereas 16 cases were diagnosed with recurrence (2 of them following successful pregnancies) who required definitive treatment. For the patients under 40 years of age, fertility preserving treatment ended up with successful pregnancies in 41.6% (5/12) of cases. Our case presented herein is a 39-year old woman who was initially diagnosed with UTROSCT by hysteroscopic biopsy. To our knowledge, our case is the first to be treated laparoscopically for the recurrence of UTROSCT following laparoscopic fertility sparing surgery proceeding with successful pregnancy.
Conclusion: Fertility sparing surgery via laparoscopic approach seems to be a considerable option of treatment for women with UTROSCT in their reproductive ages. Minimally invasive surgery for UTROSCT is suggested to be applicable in both conservative and definitive management.
