Endoarterial pulmonary metastasis of malignant trophoblast associated with a term intrauterine pregnancy.
A previously healthy gravida 4, para 3, developed preclampsia and progressive dyspnea at the 37th gestational week and had bilateral pulmonary infiltrates on chest roentgenogram. She delivered a healthy, term, male infant with a normal appearing placenta. Postpartum, her respiratory status gradually worsened. A lung biopsy on the 20th postpartum day revealed intravascular trophoblasts, diffuse arteriolar thrombosis with pulmonary infarction, and subacute interstitial pneumonitis. Combination chemotherapy was instituted, but the patient died from respiratory insufficiency.
