Choriocarcinoma (stage IV) despite two normal dilation and curettages: A case report


Obstetrics & Gynecology International Journal

Abstract

Choriocarcinoma is a highly metastatic subtype of gestational trophoblastic neoplasia (GTN) following pregnancy. It can arise from any type of pregnancy (50% occur after term pregnancies, 25% after molar pregnancies, and 25% after early pregnancy loss and ectopic pregnancies) (Soper, 2006).
This case report describes an interesting diagnostic conundrum with normal histology findings on two separate endometrial dilation and curettages (D&C) in the context of high clinical suspicion for molar pregnancy that progressed to stage IV choriocarcinoma with brain and lung metastasis.
The patient presented to our hospital nearly aphasic but would only say “molar pregnancy”. Due to her brain metastasis and worsening intraparenchymal hematoma, she underwent craniotomy confirming the diagnosis. After stabilization, she was transferred to a quaternary care center to complete chemotherapy with etoposide, methotrexate, actinomycin, cyclophosphamide, and vincristine and had a good response.
At this time, there is no clear explanation for two negative D&Cs in the context of a classic case of choriocarcinoma with progression from a molar pregnancy. It reminds us as providers that medicine remains an imperfect science and requires astute clinical judgement to properly treat patients when diagnostic data such as pathology findings and lab values appear to be incongruent with the larger clinical picture.
