Multiple primary lung cancer is classified into a synchronous primary lung cancer or a metachronous primary lung cancer. Both are rarely encountered disease entities. We report our surgical experience of each one case of synchronous and metachronous primary lung cancer.

Background: Nearly 10% of cancer patients will develop a second primary cancer within ten years after surgical removal of the primary tumor. The detection of risk factors for developing multiple primary tumors would be important This study was conducted to evaluate the clinical characteristics and abnormal p53 expression of lung cancer associated with multiple primary cancer(MPC). Method: Clinical characteristics and abnormal p53 expression were compared between 20 cases of lung cancer(NSCLC ; 16 cases, SCLC ; 4 cases) associated with MPC and 26 cases of primary non-small cell lung cancer. Result: MPC associated with lung cancer was gastric cancer(8), lung cancer(2), esophageal cancer(2), colon cancer(2), laryngeal cancer(1), bladder cancer(1), small bowel cancer(l), adrenal cancer(1), hepatocellular carcinoma(1), and breast cancer (1) in order. The clinical stage of primary NSCLC was relatively advanced, but NSCLC associated with MPC was even distribution at each stage. The detected incidences of abnormal p53 expressions were 62.5% in NSCLC associated with MPC and 76.9% in primary NSCLC(p>0.05). Conclusion: There was no difference in abnormal p53 expression between non-small cell carcinoma associated with multiple primary cancer and primary non-small cell carcinoma.

Background: With the advances of video technology, thoracoscopic surgery has been applied to various areas of the thoracic surgical fields including major surgeries. Now a days,-thoracoscopic surgery is Performed as a procedure of choice for primary spontaneous pneumothorax. But the operative indication for the primary spontaneous pneumothorax has not been changed since the last few decades, although the procedure of choice was changed from open thoracotomy to thoracoscopy. Therefore, we thought new treatment strategy will be necessary for the management of primary spontaneous pneumothorax. Material and Method: Between January 1998 and December 1999, 149 primary spontaneous pneumothorax patients were admitted to the Kyungpook National University Hospital. Result: Of these patients, 177 were first attack pneumothoraces and the number of total attacks were 250. Conclusion: Analyzing the amount of pneumothorax, methods of treatment, number of recurrences, recurrence rate and hospital stay, we propose a critical pathway for establishing new treatment strategy for the management of primary spontaneous pneumothorax.

Giant cell tumor rarely occurs in ribs. Usually it is located in the posterior arc. We reported a very rare case of primary giant cell tumor of rib in the anterior arc with review of literatures.

경부기도의 종양은 편평상피암과 함께 이비인후과의에게 있어서 호흡곤란 환자의 감별진단을 위해 매우 중요한 임상적 의미를 갖는다. 종양은 암종에 의한 사망률의 0.1%이하를 차지하는 드문 질환이며 선양낭성암종은 기도의 원발성 종양중 두 번째로 많은 질환이다. 갑상선종양의 기도의 직접적인 침범이 흔히 발견되는 상태이며, 그다음으로 편평상피암, 선양낭성암종이 기도의 원발성 종양으로 흔한 질환이다. 갑상선의 악성종양이 기도의 벽이나 내강을 침입하는 것과 마찬가지로, 기도의 원발성 악성종양도 흔히 갑상선을 침범하여 갑상선의 종괴처럼 발현할 수 있다. 본 연구는 이와 같이 갑상선의 악성종양과 유사한 임상경과를 보이는 기도의 선양낭성암종의 향후 감별진단을 위해 4명의 조직학적으로 증명된 갑상선을 침범하는 기도의 선양낭성암종환자의 임상기록과 전산화 단층촬영소견을 후향적으로 관찰하였다. 전산화 단층촬영에서 이들은 기도에 넓은 기저부를 가지고 갑상선을 밀고있는 균일한 음영의 일반적으로 부드러운 경계를 가지는 종괴로 보였으며, 횡단면과 두정면에서 모두 기도 벽의 비후소견을 보였다. 이러한 소견은 기도의 원발성 선양낭성암종의 감별에 도움이 될 것으로 생각된다.

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.

Primary pulmonary malignant melanoma is an extremely rare type of melanoma. The radiologic features of primary pulmonary malignant melanoma are nonspecific; however, it almost always presents as a well-demarcated round or lobulated solitary solid nodule or mass. Herein, we report the case of a 78-year-old male with primary pulmonary malignant melanoma that was mistaken for primary pulmonary adenocarcinoma with lepidic growth and was seen as bilateral multiple subsolid nodules on CT.

Primary pulmonary angiosarcomas are extremely rare tumors. The diagnosis is often delayed due to nonspecific symptoms, mimicking pulmonary embolism and require careful clinical evaluation to exclude metastasis from the heart, pericardium, and distant extrathoracic sites. Most diagnosis are made postmortem. We report a case of primary pulmonary angiosarcoma histopathologically confirmed postoperatively, which was clinically suspected endobronchial carcinoma with endobronchial obstruction with relavant literature review.

Primary malignant melanoma of the esophagus(PMME) is an extremely rare tumor with only scattered case reports. The treatment of choice is surgical resection. However, the prognosis is poor. Recently we experienced one case of primary malignant melanoma of the esophagus in a 60-year-old male patient. Esophagectomy and intrathoracic esophagogastrostomy were perfomed. The patient was discharged without specific complications.

The synchronous primary lung cancer is very rare cancer, proportion of synchronous lung cancer is about 1∼2% of total lung cancer, When pathologic type is same, preoperative diagnosis is very difficult and it may be misdiagnosed as lung to lung metastasis. We have experienced synchronous primary lung cancer of heterogenous squamous cell carcinoma.
