We report the case of a 39-year-old para-4 gravida-4 who received polychemotherapy 5-fluorouracil 600 mg/m2, cyclophosphamide 600 mg/m2 and epirubicin 50 mg/m2 for invasive breast cancer (pT2N2Mo) with extensive metastatic involvement of all 23 axillary lymph nodes removed at 29 gestational weeks. Soon after the second course of chemotherapy at 35 weeks, she developed two eclamptic tonic-clonic seizures which were treated by antihypertensive and anticonvulsive drugs and delivery of a healthy infant, 1650 g (< 10th percentile) by cesarean section. That this patient indeed suffered from eclampsia was supported by the findings of transient postpartum severe hypertension (peak 170/110 mmHg), proteinuria (peak 3.2 g/24 h), incomplete features of the HELLP syndrome (thrombocytopenia 81,000/mm3, haptoglobin < 10 mg/dl) and of DIC, and by the results of cerebral CT scanning showing two 1-cm ischemic lesions. Since the detrimental effect of antineoplastic agents on the rapidly proliferating trophoblast is well known and as abnormal placental function, such as in triploidy, trisomy or hydatiform mole, has been associated with an increased risk for preeclampsia/eclampsia, a possible causal relationship between polychemotherapy and the subsequent development of this rare disorder is suggested.

We report a case of a healthy woman - whose previous pregnancy was uncomplicated - with early onset of hypertension, proteinuria and edema, during her second pregnancy. Ultrasound examination at 19th week of amenor rhea showed a fetus with growth retardation, corresponding to 17 weeks' gestation, ascites, cardiomegaly with serious multiple congenital anomalies. Amniocentesis for fetal karyotyping revealed 69, XXX. Because of continued elevated blood pressure, increasing proteinuria and severe lethal fetal anomalies, interruption of pregnancy was suggested. It was subsequently carried out by surgery. The patient underwent renal biopsy 10 days post-partum: histology showed the presence of the characteristic pathologic renal changes of preeclampsia. A year later, she became pregnant by the same partner. The third pregnancy was uneventful. The combination of fetal triploidy and preeclampsia may suggest a causative relationship. Clinically, most cases manifest as severe early-onset preeclampsia and must be differentiated from essential hypertension and a chronic glomerulonephritis (GN), which becomes symptomatic during pregnancy. When a fetus has triploidy, the counseling should stress the high incidence of preeclampsia; particularly when fetal anomaly is not compatible with life, it is well known that delivery of the fetus is curative in this syndrome. This information is important in counseling patients who are hesitant to terminate the pregnancy purely for a fetal abnormality, even if lethal.

A 35-year-old Japanese woman for whom a previous health checkup showed normal blood pressure and urinalysis results without serological abnormalities developed nephrotic syndrome with severe hypertension at 15 gestational weeks. The renal biopsy performed at 17 weeks of gestation showed severe glomerular capillary endotheliosis. By means of electron microscopy, no electron-dense deposits were observed in glomeruli, and foot-process arrangement was normal. Histological findings indicated the patient's glomerular damage was caused by the mechanisms of preeclampsia. The patient underwent an elective abortion at 18 weeks of gestation. Clinical abnormalities vanished completely within 3 months after the elective abortion, which provided additional evidence that proteinuria and hypertension were caused purely by pregnancy. In general, the term preeclampsia refers to new onset of hypertension and proteinuria after 20 weeks of gestation. When proteinuria or hypertension is newly observed before 20 weeks of gestation, they are practically associated with triploidy, trophoblastic disease, or antiphospholipid syndrome. However, our case was not associated with them. Therefore, we called this case "pure" preeclampsia. We confirm the notion for the first time that preeclampsia associated with glomerular capillary endotheliosis can occur before 20 weeks of gestation. In addition, this report describes the earliest onset of preeclampsia compared with previously published reports. We also discuss causes of preeclampsia in early gestation and refer to the issue of the application of renal biopsies during pregnancy.
