Choriocarcinoma with multiple lung metastases from complete hydatidiform mole with coexistent fetus during pregnancy.

Gestational trophoblastic neoplasm (GTN) is a serious morbidity of complete hydatidiform mole with coexistent fetus (CHMCF) and usually develops after termination of pregnancy. Here we report a case of choriocarcinoma derived from CHMCF during pregnancy. A 33-year-old multiparous woman with suspected CHMCF was admitted with a severe cough. Computed tomography revealed multiple lung metastases. Cesarean section and hysterectomy were performed at 31 weeks of gestation on diagnosis of high-risk GTN from International Federation of Gynecology and Obstetrics (FIGO) scoring. A live female infant weighing 1390 g was delivered. Choriocarcinoma was diagnosed from pathological findings. The patient received multi-agent chemotherapy and was discharged on the 40th postoperative day. In conclusion, CHMCF can result in high-risk GTN during pregnancy. For a suspected GTN, diagnosis from FIGO scoring should determine treatment strategy. If patients with CHMCF wish to continue their pregnancy, careful follow-up, including regular chest radiography and ultrasonography, is warranted.

Preeclampsia as a Manifestation of New-Onset Systemic Lupus Erythematosus during Pregnancy: A Case-Based Literature Review.

Introduction New-onset systemic lupus erythematosus (SLE) during pregnancy is rare and difficult to diagnose, especially in cases that manifest as preeclampsia. We report a patient with new-onset SLE that manifested as preeclampsia during pregnancy and provide a review of the literature to identify factors for a rapid diagnosis. Case A 32-year-old primigravid Japanese woman was diagnosed with severe preeclampsia and underwent emergent cesarean section at 29 weeks of gestation. Her hypertension and renal disorder gradually improved after the operation, but her thrombocytopenia and anemia worsened. SLE was diagnosed on postoperative day 5 by a comprehensive autoimmune workup. She was discharged on postoperative day 34 with remission. Conclusion Our case and previous reports suggest that distinguishing underlying SLE from preeclampsia in the third trimester is particularly difficult. Helpful factors for diagnosis of suspected SLE in these cases were persistence of symptoms and new atypical symptoms for preeclampsia revealed after delivery (e.g., fever, renal disorder, and thrombocytopenia).
