Necrosis of myometrial choriocarcinoma with fulminating sepsis complicating chemotherapy for trophoblastic tumor.

We report a patient who developed metastatic gestational choriocarcinoma following delivery of a normal, healthy child that, however, was anemic and required blood transfusion. The patient developed secondary postpartum hemorrhage over a period of several weeks and required curettage and myometrial contractants to control the bleeding. At the time of diagnosis the patient had extensive pulmonary metastases and ultrasound showed full penetration of the myometrium by tumor. Immediately following the second course of chemotherapy with etoposide, methotrexate, and actinomycin D, alternating with cyclophosphamide and vincristine, the patient developed sepsis associated with a uteroperitoneal fistula and required hysterectomy. The sepsis was associated with disseminated intravascular coagulopathy and adult respiratory distress syndrome. However, the patient's tumor was exquisitely sensitive to chemotherapy and with good intensive care unit support and chemotherapy the survived without residual scar except for the loss of reproductive function. There are two lessons to be learned from these events: (1) The syndrome of secondary postpartum hemorrhage with a fetus that is anemic spells a diagnosis of choriocarcinoma; and (2) color Doppler flow vaginal ultrasound performed at the time of presentation of trophoblastic tumors may be useful to show full penetration of the myometrium by tumor which may be a warning of possible scar rupture in a subsequent pregnancy.
