Metastatic Ovarian Clear Cell Carcinoma in the Context of In Vitro Fertilization Pregnancy

Abstract EN

Adnexal masses are routinely encountered in the clinical practice.

However, adnexal masses during pregnancy are incidental findings and usually resolve spontaneously or can be managed conservatively during pregnancy due to their benign nature.

Ovarian malignancy is a rare event to occur during pregnancy.

Only a few cases of ovarian clear cell carcinoma (OCCC), a subtype of epithelial ovarian cancers, have been reported in pregnancy and all of which have undergone cystectomy or pregnancy termination prior to the last trimester of pregnancy.

We present a unique case of OCCC in a pregnant 38-year old female of Asian ethnicity with endometriosis and an in vitro fertilization (IVF) pregnancy.

The OCCC, initially suspected to be of benign nature, was removed via emergency cesarean section during delivery in the late preterm period.

The Positron Emission Tomography scan performed a few weeks after delivery confirmed metastatic lesions.

Our case study not only emphasizes the need for definitive treatment option for endometriosis but also a close surveillance of all masses diagnosed during pregnancy, in particular with a background of other risk factors such as endometriosis and Asian ethnicity.

In addition, our study advocates the need for the guidelines for management of such rare cases.
