Primary choriocarcinoma of the lung is extremely rare. The patient was 28-year-old female and had no specific signs and symptoms except right chest pain for 5 years. On simple chest film, 8X8 cm sized, well demarcated, homogeneous ovoid mass was found on right lower lung field. The qualitative urine \ulcorner-HCG was 17140 mIU/ml. The result of percutaneous needle biopsy highly suggested choriocarcinoma. Under the impression of primary choriocarcinoma of the lung, right middle and lower lobectomy was done. On 33 postoperative days, serum \ulcorner-HCG level was within normal limit, the patient was discharged without complications after one-cycle chemotherapy.

Primary choriocarcinoma of the lung is extremely rare and have been reported ten and several cases only in the literature. It is very difficult to confirm the "Pure primary pulmonary choriocarcinoma" clinically, so most cases that have been reported in the literature confirmed by autopsy and the prognosis is relatively poor compared with metastases. We experience one case of the primary pulmonary choriocarcinoma. She was 53 year old multiparous woman[4 \ulcorner0 \ulcorner2 \ulcorner0] who complain right chest pain for 4 years. On plain film and computerized tomogram of the thorax at admission, 2.5cmx3.5cmx5 cm sized, well demarcated ovoid mass was founded on the right middle lobe just below the parietal pleura and growing rapidly on plain film to 5cm x 6.5cm x 7cm after 15 days. We confirm the choriocarcinoma in the lung by percutaneous needle aspiration biopsy and strongly suspect primary after various examination for rule out metastases from the ovary or uterus. We perform middle lobe lobectomy because that can not confirm the primary or the metastases because there are not complete histological examination by bilateral ovariectomy and hysterectomy, and under the belief that extragestational or extragonadal primary choriocarcinoma is more resistant to the chemotherapy, and could be reduce the duration of hospitalization and the amount of chemotherapy used to achieve remission On 14th postoperative day, serum p-HCG level was returned to normal limit, and perform chemotherapy two times on 3rd and 5th week for prevention surgical traumatic hematogenous metastases or undetected microfocus, but the patient expire on 68th postoperative day due to intracerebral hemorrhage in the intracranial choriocarcinoma which strongly suspected surgical traumatic hematogenous metastases.etastases.

A 69-year-old man was admitted due to blood-tinged sputum. The preoperative examination revealed 5${\times}$2.8cm sized nodular mass on left upper lobe of the lung. The patient underwent left upper lobectomy and radical Iymph node dissection under impression of lung cancer. Postoperative pathologic examination revealed as primary choriocarcinoma of the lung. The patient expired at postoperative 58 days despite meticulous postoperative care. We planned on immediate adjuvant chemotherapy but was delayed due to postoperative pneumonia and the choriocarcinoma progressed rapidly. Primary choriocarcinoma is an extremely rare clinical entity in lung cancer with no established therapeutic guidelines available. We report a case of the primary pulmonary choriocarcinoma which was diagnosed postoperatively.

Choriocarcinoma is a germ-cell tumor that originates from syncytiotrophoblastic cells and this tumor secrets beta-human chorionic gonadotropin. It has been reported that extragonadal primary pulmonary choriocarcinoma is extremely rare. We report here on a 28-years-old woman who underwent right lower lobectomy for extragonadal nongestational primary pulmonary choriocarcinoma and she has survived for 2 years without recurrence.

The majority of choriocarcinomas occur in the uterus as gestational malignant tumors. Rarely, a choriocarcinoma appears in the gastrointestinal tract, and the tumor is assumed to arise from a different histogenetic origin as compared to tumors of other sites. A primary gastric choriocarcinoma is a rare aggressive, widely metastatic malignant tumor, and has a poor prognosis. Reported here is a case of a 69-year-old woman with a primary gastric choriocarcinoma who presented with melena, epigastric pain, and was diagnosed with a poorly differentiated adenocarcinoma based on a preoperative endoscopic biopsy. Gastrectomy with lymph node dissection, followed by postoperative chemotherapy, is the treatment of choice. Therefore, in the case of a poorly differentiated adenocarcinoma with a bleeding tendency, a meticulous examination with the suspicion of a choriocarcinoma should be undertaken.

A primary choriocarcinoma of the lung is extremely rare, and difficult to distinguish from a metastatic choriocarcinoma considering that the lung is also one of the most frequent sites of metastasis. We report a 28-year-old woman patient who was initially misdiagnosed with an ectopic pregnancy and was operated on under the impression of an unidentified malignancy of the lung, which was finally proven to be a choriocarcinoma of the lung. A pelvic examination by a gynecologist, pelvic magnetic resonance imaging and whole body fluorodeoxyglucose positron emission tomography-computed tomography was performed in order to rule out a metastatic choriocarcinoma of the lung. After a curative operation, her serum ${\beta}$-human chorionic gonadotropin (HCG) level, which was highly elevated in the initial evaluation, had decreased dramatically to the normal range. She is currently being followed up regularly without any evidence of recurrence or elevation of her ${\beta}$-HCG level.

Eighty-four patients with pulmonary metastases from gestational choriocarcinoma were treated at the Catholic Medical Center between August, 1985 and August, 1991. Among these 13 patients underwent thoracotomy with resection of pulmonary lesions and the results obtained were follows. 1] The ages of the patients ranged from 26 to 47 years, with a mean age of 31 years. 2] The frequency of chemotherapy before operation ranged from zero to 46, with a mean frequency of 13.6. 3] Four patients were operated upon for a solitary metastasis of the lung; 6 patients, for unilateral multiple metastases and 3 patients, for bilateral pulmonary metastases. 4] Eight patients underwent wedge resection; 1 patient, segmentectomy; 2 patients, lobectomy; 3 patients, open lung biopsy. The lung lesions of eleven patients showed hemorrhagic necrosis[among these, 2 patients combined with pulmonary tuberculosis]; one was non-necrotic choriocarcinoma; another one was metastatic lung carcinoma from endocrine cancer of unknown origin. 5] Among twelve patients who had managed with chemotherapy before thoracotomy three patients were in remission; among 13 patients who had undergone thoracotomy 6 patients were in remission. 6] The median survival time of these patients was 25.8 months with 3 postoperative deaths. Subsequently, in the patients with pulmonary metastases from choriocarcinoma, if the primary tumor is under control, there are no other metastases, and the patients should be able to tolerate the planned operation, it is necessary to undergo aggressive thoracotomy for diagnostic purposes; for therapeutic purposes only when the pulmonary lesion is the only remaining source of increased hCG excretion; for reduction of tumor volume to shorten hospitalization or to reduce the quantity of drugs.

Primary mediastinal choriocarcinoma is characteristically seen in young males presenting with the symptomes of cough, chest pale, and gynccomastia. A 33-year-old woman was admitted to the hospital because of severe dyspnea and chest pain which was aggravated rapidly 2 or 3 days ago. Posterior mcdiastinal mass measuring about 1 cm in diameter was seen in Chest P-A, left lateral view of chest, and chest CT. Serum $\beta$-HCG level was markedly elevated up to 200, 000 mIxt. Whole body CT and other studies could not find any lesion on ovary and uterus. But, a single nodule nEeasuring about 1 cm in diameter was identified in the brain CT. The tumor cells (syncytiotrophoblastic cells) from resected mass revealed positivity on i histochemical staining for $\beta$-HCG. She was treated with EMA-CO after resection of tumor, But, 7 months later, she was readmitted and showed cerebral hemorrhage due to metastatic choriocarcinoma. She was operated again for the brain tumor, and was doing well for further 7 months.

One hundred and twenty patients with brain metastases were seen and evaluated in the Dept. of Therapeutic Radiology, Seoul National University Hospital between 1979 and 1983. Of these, 90 Patients received whole brain irradiation with 2,000 ra4 in 1 week or 3,000 rad in 2 weeks for Palliative Purpose and 30 patients failed to complete the planned treatment. Carcinoma of the lung(44 cases), choriocarcinoma(11 cases), breast(8 cases) were common Primary tumors of 90 patients receiving planned treatment. Symptomatic subjective response was obtained in $92\%$ of Patients and meurologic functional improvement was obtained in $42\%$ of patients. Median survival was 6.4 months in patients with complete treatment an·d less than 2 months in Patients with incomplete treatment, overall survival rate at 1 year and 2 year were $26\%,\;16\%$ in Patients with complete treatment and $8\%,\;0\%$ in patients with incomplete treatment. Primary site, extent of metastases and interval from diagnosis of primary tumor to brain metastases were identified as prognostic factors.

Pulmonary choriocarcinoma is a very rare tumor in men. Herrein, the case of a pulmonary choriocarcinoma in 39-year-old man, and whether it had a primary nature, is reported. He denied any prior medical illness, but was admitted to our hospital with a history of a cough, and progressive dyspnea and hemoptysis 2 and 1 week duration, respectively. Chest radiographs on admission revealed a huge lung mass, 10 cm in diameter, in the left upper lung field, with left pleural effusion. Although biopsies using several diagnostic methods for the pathological confirmation were attempted, the pathology was not confirmed. Finally, the patient died after 2 months of regression. An autopsy of the lung was then performed.
