Primary lung choriocarcinoma masquerading as a metastatic gestational neoplasm.
Primary lung choriocarcinoma has rarely been reported. In females, previous pregnancies and other sources of trophoblastic tissue such as a nongestational gonadal choriocarcinoma must be excluded before the diagnosis can be made. Here we present a young female patient initially diagnosed as having a metastatic gestational neoplasm who was unresponsive to standard single and multiagent chemotherapy. A total abdominal hysterectomy and bilateral salpingo-oopherectomy failed to reveal the source of production of beta HCG. At the time of her thoracotomy and lobectomy, performed for a lung nodule, she was found to have a primary lung choriocarcinoma. The patient received no further chemotherapy and has remained disease free for more than 3 years. This is the first recorded case of a lung choriocarcinoma that has been successfully treated where the patient has remained free of disease for more than 1 year.
