Mediastinal lymph node involvement [N2 disease] is generally accepted as an important factor influencing the outcome of patients with lung cancer.The long-term survival rates of completely resected patients with N2 disease are frequently reported from 15% to 30%.To improve the management and the outcome of patients with resectable N2 disease, we analyzed the survival rates and the prognostic factors for resected N2 lung cancer. Between August 1989 and September 1993, we experienced 27 patients with N2 disease of 115 surgically treated lung cancer at the Department of Thoracic and Cardiovascular Surgery, Asan Medical Center, Ulsan University Medical School. Of these 27 N2 disease 4 had only an exploratory thoracotomy, and 23 underwent pulmonary resection by pneumonectomy[15], bilobectomy[3], lobectomy[4] and sleeve lobectomy[1].All of resected 23 patients received postoperative adjuvant chemotherapy[3], radiotherapy[2] or combined chemo-radiotherapy[18].Complete follow-up was obtained in 23 patients and median survival was 22 months and overall 1-year and 2-year survival rates by Kaplan-Meir method were 65 % and 45 %, respectively. Survival differences according to histology, tumor location, number of positive nodal station and operative method were not significant, statistically. Conclusively, we think that in resectable N2 lung cancer, complete tumor resection and mediastinal lymph node dissection, and postoperative adjuvant therapy should be done to improve the survival.

Thymolipoma is extremely uncommon benign mediastinal tumor consisting of fatty and thymic tissue. Only 50 verified cases have been reported in the world literatures. This one case is the first reported example of surgically treated thymolipoma associated with spontaneous pneumothorax. A thirty-two year old male patient had been in good health until two days prior to admission, when he noted sudden dyspnea associated with an aching pain over the left precordium. The dyspnea and chest pain had become progressively worse. The physical examination revealed that left hemithorax was tympanic sound on percussion and absence of breathing sound on auscultation and point of maximal impulse was located on the 4th intercostal space at the left sternal border. Emergency closed thoracostomy was performed under the impression of tension type spontaneous pneumothorax of the left lung. After closed thoracostomy, point of maximal impulse was not changed inspire of full expansion of the left lung and chest X-ray was strongly suggested pericardial effusion or cardiomegaly which couldn`t account for by clinical course and hemodynamic evidence. EKG, echocardiogram, bronchofiberoscophy, bronchogram and diagnostic thoracentesis was performed. On Dec. 8, 1980, operation was performed under the impression of mediastinal tumor in the anterior mediastinum. At left posterolateral thoractomy, a large fatty mass, measuring 35 x 27 x 13 Cm in dimension and weighing 3350 gm, was resected and multiple bullae on the apicoposterior segment of the left upper lobe was resected and continuously sutured. The pathologic diagnosis of the fatty mass was thymolipoma. The postoperative course was uneventful and discharged in good general conditions.

Currently, the prevalence of gastroesophageal junction adenocarcinoma (GEJAC) is increasing in both Asian and Western countries, although the increasing rate in Asian countries is much slower than in Western countries. With these current trends, concerns regarding the surgical treatment method are also increasing among gastrointestinal surgeons. However, the surgical treatment for GEJAC has been a controversial issue for a long time due to the relative scarcity of this tumor and its characteristics from its borderline location. Recently, a large-scale prospective study of this tumor has been conducted in Japan, and the results are now available. The results of this study will be helpful for understanding this tumor. In this article, the pattern of lymph node metastasis of GEJAC is reviewed, and the extent and method of lymph node dissection for this tumor are discussed and proposed based on the review.

Endodermal sinus tumor of the mediastinum is a very rare malignant tumor, usually affecting young adolescents, and its histologic findings are characteristic as that of gonadal germ cell origin. We describe the cytologic finding of fine needle aspiration of mediastinal endodermal sinus tumor in a 19-year-old male patient, comparing with tissue section. The tumor cells in smears were usually in tight clusters with large overlapping cells, which were arranged in a papillary or microacinar pattern, suggesting carcinoma. The tumor cells were large, round or oval with a small amount of cytoplasm which was occasionally vacuolated and had indistinct border. The nuclei were large, pleomorphic, and vesicular with large prominent nucleoli. The tissue sections showed typical findings of endodermal sinus tumor. Careful correlation of cytological findings and the serum alpha -fetoprotein level would be helpful to confirm the diagnosis.

Primary thymic adenocarcinoma is a very rare malignancy of the anterior mediastinum with no standardized treatment. A 36-year-old male patient presented with hoarseness over the past 3 months. A chest computed tomography (CT) scan showed an infiltrative mass to the proximal vessels and aortic arch in left upper mediastinum ($4.1{\times}3.1{\times}5.4cm$). Brain magnetic resonance imaging (MRI) showed focal lesions, suggesting metastasis in the left frontal lobe. A thoracoscopic biopsy of the mediastinal mass confirmed a primary thymic adenocarcinoma forming a glandular structure with atypia of tumor cells. The patient received four cycles of systemic chemotherapy, consisting of etoposide and cisplatin, with concurrent radiotherapy (6,000 cGy/30 fractions) to the mediastinal lesion and the metastatic brain lesion (4,200 cGy/12 fractions). A follow-up chest CT scan and brain MRI showed a decrease in the size of the left upper mediastinal mass and brain lesion. We report a rare case of the primary thymic adenocarcinoma with a literature review.

연구 배경 : 종격동 종양과 낭종은 최근 정기적인 건강 검진의 보급 및 진단 수기의 발달로 진단율이 증가하고 있는 추세로 장기간의 경과를 통한 우리나라에서의 특징적인 임상 양상에 대한 연구가 필요하다. 대상 및 방법 : 본 연구는 연세대학교 의과대학 세브란스병원에 입원하여 병리조직학적으로 확진된 환자들을 대상으로 이전 25년 동안의 보고와 1985년 7월부터 2002년 6월까지 최근 17년 동안의 결과를 비교하였다. 결 과 : 전체 종격동 종양 479예 중 흉선종이 183예(382%)로 가장 많았고, 종격동 구획에 따른 분포는 이전 보고와 유사하였다. 흉부 X-선 촬영상 우연히 발견된 경우가 174예(36.3%)로 이전의 보고(10.9%)보다 더 많았다. 악성 종양과의 감별을 위해 시행한 경피세침흡인생검의 전체 진단율은 68.6%이었고 악성 종양에서 80.9%로 진단율이 높았다. 전체 479예 중 수술적 절제를 시행한 환자는 405예(84.6%)이었고, 완전 절제율은 91.1%로 이전의 보고(78.8%)보다 더 높았다. 이전 보고와 본 연구 결과를 종합한 42년 간의 결과는 총 662예 중 흉선종이 205예(31.0%)로 가장 많았다. 결 론 : 종격동 종양과 낭종은 최근 진단율과 완전절제를 통한 적극적인 치료가 급속히 증가하고 있는 추세이며, 특히 흉선종의 비율이 현저히 증가하여 이에대한 관심이 필요하다. 종격동 종양에 대한 경피세침흡인생검(중심침생검 포함)의 전체 진단율이 68.6%이고, 악성 종양에서 80.9%로 높아 수술적절제 전 악성 종양과의 감별을 위한 일차적인 진단법으로 유용하다고 생각된다.

배경: 폐암환자의 정확한 병기 판단을 위한 비디오흉강경수술은 흉강내를 직시하며 병변의 의심이 있는 부위의 생김을 실시할 수 있으므로 기존의 방법에 덧붙여 절재술 여부를 결정하는데 중요한 역할을 할 것으로 생각된다. 본 조사의 목적은 폐절제술 전 비디오흉강경수술의 역할을 평가하기 위하여 실시하였다. 대상 및 방법: 흉부전산화단층촬영술등과 종격동경으로 평가를 실시하여 절제술을 하려는 폐암환자에서 개흉전 비디오흉강경술을 실시하였다. 총 37예에서 흉강경수술을 실시하였으며 흉강경수술전 병기는 TNM병기로 1병기 18예, II병기 7예, III병기가 12예였다. 결과: 37예 중 15예는 흉강내 유착, 횡격막 또는 흉벽의 종양침범과 폐문부 종괴의 거대로 인하여 종격동에 접근이 어려워 흉강경수술이 용이치 않아 실시할 수 없었으며 이들 예에서는 전제술 후 병리조직학적으로 6예에서 종격동림프절에 암 전이가 확인되었다. 흉강경수술을 실시한 22예 중 2예는 흉강경수술 전 병기평가에선 N0이었으나 N2로 확인되어 개흉하지 않았고 20예에서는 흉강경수술상 종격동림프절에 천이가 확인되지 않아 절제를 실시하였다. 그러나 이중 5예에서 절제술 후 병리조직학적으로 N2로 확인되었다. 결론: 이상의 결과를 보아 흉막강내의 유착, 흉벽과 횡격막에 종양침범이나 거대종괴등으로 인하여 흉강경을 통한 흉강내 관찰이 어려워 흉강경술을 진행할 수 없는 예들이 많이 있으므로 비디오흉강경술의 적용에 신중을 기하여 할 것이나, 흉강경을 통한 관찰과 생검으로 적은 예들에서지만 불필요한 개흉을 피하는데 도움이 되었다.

해면상 혈관종은 종격동에 발생한 혈관종중 가장 많은 형태로 주로 전종격동에 발생하고 그 빈도가 매우 드물다. 환자는 13세된 여아로 우연히 발견된 종격동 종괴로 수술적 절제를 하여 해면상 혈관종으로 판명되었다. 술후 추적한 x-ray 검사상 재발의 소견이 없으며 수술적치료시 너무 광범위한 무리한 박리와 절제는 필요하지 않을 것으로 보인다.
