Persistent low-grade endometrial stromal tumor during two consecutive pregnancies - a case report and review of literature

The authors report a case of persistent endometrial stromal tumour during two consecutive pregnancies. The diagnosis of endometrial stromal sarcoma (ESS) is difficult by fragmented tissue. There were a total of 19 reported cases of pregnancy after conservative management of endometrial stromal sarcoma. Monitoring of disease during pregnancy is challenging, although most patients remain in a stable condition with a follow-up duration of 2-60 months. Although the present patient had a favorable disease outcome despite having co-existing ESS sustained throughout two term pregnancies, the current evidence on the safety of this approach is still scarce and thorough counseling is mandatory if any young patients wish to retain their fertility potential.
