A case of recurrent tumor emboli secondary to choriocarcinoma is described. The patient presented with obvious pulmonary hypertension and was diagnosed and treated as a case of multiple pulmonary embolism. Information which suggested the possibility of tumor emboli was indeed present but recognized only retrospectively.

A rare cause of pulmonary embolism and pulmonary artery hypertension in young women is choriocarcinoma growing in the pulmonary artery. This growth is reversible, and the disorder can be cured. We describe three patients with this feature who have been treated with appropriate high-risk chemotherapy and who are now in remission. Contrast-enhanced computed tomography can be used to identify major emboli, and progress of the disease can be monitored by serial ventilation/perfusion scans and measurement of serum human chorionic gonadotropin. Recognition of this rare syndrome is important because of the generally excellent outlook with appropriate treatment.

Choriocarcinoma was found in the lung of a 34-year-old woman. Examination of the patient's entire body, especially the genital tract, failed to disclose foci of choriocarcinoma other than that in the right lung. After surgery, the levels of human chorionic gonadotropin in the blood and the urine fell. It was concluded that the choriocarcinoma of the lung was, in fact, the primary tumor. The genesis of choriocarcinoma was also studied in ten patients who died after delivery or abortion. Autopsy disclosed trophoblasts in the pulmonary arteries in nine of these ten patients. These findings suggest that primary choriocarcinoma in women is due to pulmonary embolism caused by trophoblasts at the time of abortion or delivery.

A case, unique in the literature, is reported in which a primary carcinoma of the liver presented a right-sided heart failure and pulmonary hypertension. The diagnosis of hepatocarcinoma was established by needle biopsy of the liver. Later, postmortem examination demonstrated that the pulmonary arterial tree was severely compromised by multiple tumor microemboli, despite the persistent lack of characteristic roentgenographic abnormality in our patient. In reviewing the literature, we found rare cases of occult renal cell carcinoma, choriocarcinoma and one of occult hepatocarcinoma, which presented as pulmonary embolism. These were diagnosed by pulmonary embolectomy, human chorionic gonadotrophin levels or autopsy, respectively. In another small group of reported cases of known carcinoma (gastric, breast, colonic) the patients had a clinical picture of "idiopathic" pulmonary hypertension or of pulmonary hypertension with pulmonary metastases. Pulmonary hypertension in these cases resulted from carcinomatous lymphangitis and/or tumor microembolization, as in our case. We report this case to emphasize the necessity of including occult carcinoma in the differential diagnosis of pulmonary hypertension and right ventricular failure.

Major pulmonary embolism occurring insidiously over several weeks (subacute massive pulmonary embolism) has a high mortality and may not respond well to standard anticoagulant or thrombolytic treatment. A priming dose of plasminogen was used to enhance thrombolysis produced by a streptokinase infusion in five consecutive patients with subacute massive pulmonary embolism. In each patient a dramatic clinical improvement occurred with a substantial increase in pulmonary blood flow. All five patients survived to leave hospital. Malignant disease was the underlying cause of embolism in three patients, two of whom died of their malignant disease in the six months after treatment of their pulmonary embolism. The third patient with malignant disease had a choriocarcinoma; at least some of the pulmonary obstruction may have been tumour tissue but this obstruction was dramatically cleared by the treatment. The use of a combination of plasminogen with streptokinase should be considered in severely ill patients with subacute massive pulmonary embolism, particularly if other treatment, including streptokinase alone, has failed.

We report the first case of choriocarcinoma occurring during the course of systemic lupus erythematosus (SLE). This choriocarcinoma was revealed by pulmonary metastasis associated with pulmonary hypertension secondary to neoplastic thrombi and pulmonary embolism, in parallel to a flare up of the SLE. The role of hormones in SLE is discussed.

A 42-year-old woman with choriocarcinoma required emergency pulmonary embolectomy under cardiopulmonary bypass. After diagnosis of choriocarcinoma was confirmed by examination of tumor emboli specimens, the patient was treated and had complete remission by chemotherapy over a 6-month period. Although rare, choriocarcinoma should be considered in the differential diagnosis of fertile women presenting with pulmonary embolism.

Pulmonary embolism (PE) is a fatal disease that is very rare in young people. A 21-year-old man developed PE because of a retroperitoneal tumor. The inferior vena cava (IVC) was obstructed by the tumor, and thrombus existed in the right common iliac vein. Thrombolysis and heparinization improved his symptoms prior to urgent tumor resection. A temporary IVC filter was inserted the day before the operation, but 8 h later fatal massive PE occurred. At autopsy, the retroperitoneal tumor was revealed as a metastatic choriocarcinoma. Prophylactic use of a temporary IVC filter might have paradoxically induced recurrence of massive PE in this case.

Pulmonary embolism carries a significant morbidity and mortality. Metastatic choriocarcinoma presenting as pulmonary embolism is a rare event. Here, we report a case of a 25-year-lady with a history of worsening shortness of breath for 4 months who was treated as a case of pneumonia and tuberculosis. Owing to the worsening condition, she had a contrast enhanced computed tomography (CECT) chest done and was diagnosed to have pulmonary embolism. She underwent pulmonary embolectomy. The histopathological examination of the embolus revealed it to be metastatic choriocarcinoma. She showed a good response to chemotherapy. Metastatic choriocarcinoma should be considered as a differential diagnosis in females presenting with pulmonary embolism.

Cases of pulmonary embolism and pulmonary artery hypertension caused by choriocarcinoma represent a rare clinical emergency. We report a case of a 25-year-old woman who presented with pulmonary embolism and hypertension and died soon after complete pulmonary embolectomy. A related literature review revealed that almost all of these patients had previously experienced a spontaneous abortion (average, 6 months) and were not pregnant.
