We report rare cases of myxoid chondrosarcoma and meningomyelocele mimicking as neurogenic tumor in the posterior mediastinum. This lesions clinically mimicked neurogenic tumor due to its location and dumbbell shape appearance. The histogenesis of myxoid chondrosarcoma is discussed as skeletal origin from the thoracic vertebrae, and meningomyelocele is ectopic harmatoma lesion of C.N.S. or meningx. This lesions is concluded that distinguished for the differential diagnosis among Neurogenic tumor arising in the posterior mediastinum.

염증성 근섬유모세포종은 드문 질환이며 인체의 거의 모든 위치에서 발생할 수 있다. 흉부영역에서 염증성 근섬유모세포종이 주로 발생하는 위치는 폐와 기관지이다. 종격동에서 발생한 염증성 근섬유모세포종은 보고된 경우가 드물다. 흉부 방사선 촬영에서 우연히 발견된 후종격동 종괴를 가진 환자에서 종괴적출술을 시행하였다. 조직검사결과 염증성 근섬유모세포종으로 진단되었고, 결핵 PCR 양성을 보였다. 본 증례에서 결핵이 염증성 근섬유모세포종의 유발인자로 고려될 수 있었다.

We have experienced 47 cases of primary mediastinal tumors & cysts in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital, from September, 1979 to November, 1990. The results were as follows: 1. The age distribution was from 6 months to 69 years old and the mean age was 32.3 years old. Of all 47 primary mediastinal tumors and cysts, 21 patients were male and 26 patients were female. 2. The neurogenic tumors[11 cases, 23.4%] were most frequently encountered and followed by thymoma[10 cases. 21.3%] and teratodermoid[9 cases, 19.1%]. 3. The anterosuperior mediastinum[59.6%] was most common tumor location, and followed by posterior mediastinum[25.6%], middle mediastinum[14.9%]. 4. The most common tumors were thymoma and teratodermoid at anterosuperior mediastinum, benign cyst at middle mediastinum, and neurogenic tumor at posterior mediastinum 5. The malignant tumors were 10 cases[21.3%] of the 47 cases and they were all symptomatic. 6. The most common chief complaint at admission was chest pain or discomfort[34%], and followed by coughing[23.4%], and dyspnea[17%]. 7. The successful complete removal was done in 37cases of benign tumors and cysts. In malignant cases, the surgical intervention was done in 3 cases, and 6 cases were treated with irradiation and chemotherapy, and 1 case was only biopsied. 8. The postoperative complications were developed in 7 cases[14.6%]. There was no case of hospital mortality.

Mediastinal tumors which are originated in mediastinum or probably metastasized from other organs have long fascinated the surgeon because of difficulty of diagnosis and treatment. This report is the analysis of the 26 cases of mediastinal tumors, experienced in the Department of the Thoracic and Cardiovascular Surgery, Chosun University Hospital from January 1978 to January 1985. The result are as follows; 1. The age distribution was 10 months to 68 years old and the average mean age was 34.7 years old. 2. Subjective symptom were as follows: Dyspnea [69.2%], Coughing [42.3%], Chest pain [30.8%], Back pain [15.4%] and Numbness of extremities [15.4%]. Objective signs were as follows: Decreased breathing sound [53.3%], Pleural effusion and hemothorax [34.6%], Palpable neck mass [34.6%], SVC Syndrome [19.4%] and Bloody sputum [15.4%].

배경: 원발성 비소세포성 폐암에서 종격동 림프절 전이는 중요한 예후인자 중의 하나이다. 이 연구는 원발성 비소세포성 폐암으로 수술 받은 환자에서 폐엽에 따른 종격동 림프절 전이 양상을 파악하여 적극적인 종격동 림프절 절제술을 시행하고 그로 말미암아 병기 결정에 도움이 되고자 시행하였다. 대상 및 방법: 1998년 1월부터 2005년 12월까지 원발성 폐암으로 완전한 종격동 림프절 절제술과 함께 근치적 폐 절제술을 시행받았던 293명의 환자를 대상으로 의무기록을 토대로 후향적 연구를 시행하였다. 환자의 평균나이는 $63.0{\pm}8.3$세($37{\sim}88$세)였으며 남자가 220명(75.1%)이었다. 원발성 종양과 림프절의 분류는 Mountain등이 발표한 TNM 병기를 근거로 하였으며 조직학적 분류는 WHO 분류를 기초로 하였다. 통계 처리는 Fisher's exact test와 chi-square test를 사용하였고 p 값이 0.05 미만일 경우 의의 있는 결과로 받아들였다. 결과: 전체 환자 중에서 폐엽절제술은 180명, 폐이엽절제술은 50명, 소매폐엽절제슬은 10명, 전폐절제술은 53명에서 시행되었다. 수술 후 폐종양의 병리학적 진단은 선암(adenocarcinoma)이 124명, 편평세포암(squamous cell carcinema)이 138명, 선편평세포암(adenos-quamous cell carcinoma)이 14명이었으며 카르시노이드종양(carcinoid tumor) 1명, 대세포암(large cell carcinoma) 8명, 암육종(carcinosarcoma) 1명, 점액표피양암(mucoepiderrnoid carcinoma) 2명, 미분류된 암이 5명이었다. 술 후 TNM 병기는 IA가 51명, IB가 98명, IIA가 9명, IIB가 41명, IIIA가 71명, IIIB가 16명, IV가 6명이었다. 전체 환자 중 N2 이상의 병기를 보인 환자는 25.9%(76명)이었고 그 중 우상엽의 병변인 경우 4번 림프절로의 전이가 가장 많았으며 좌상엽의 병변인 경우 4번과 5번, 나머지 폐엽에서는 7번 림프절로의 전이가 가장 많았으나 통계적 의의는 없었고 도약 전이가 전체 환자 중12.3% (36명)에서 발견되었다. 결론: 원발성 비소세포성 폐암의 폐엽에 따른 종격동 림프절 전이 양상은 뚜렷한 규칙이 없으며 도약 전이도 12.3%에서 발생되었으므로 완전한 종격동 림프절 절제술만이 정확한 병기를 결정하는데 도움이 되고 환자의 예후를 결정하는데 중요한 역할을 한다고 생각한다.

Cystic intrathoracic lesions of foregut origin are now well recognized and account for approximately 10% of lesions presenting as mediastinal tumors. The terminology used to describe mediastinal endodermal cysts has been confused and sometimes ambiguous. The embryological derivation of these lesions has been the cause of much speculation. It Is suggested that these lesions should be classified Into three main categories based on embryology bronchogenic cyst[resulting from a defect of lung budding], Intramural esophageal cyst[true duplication], and enteric cyst[resulting from the split notochord syndrome]. This communication describes a 26 year old man with intramural esophageal cyst who was diagnosed as posterior medlastlnai tumor preoperatively and cured with extirpation of the cyst.

Cystic hygroma is benign overgrowth of the lymphatic vessels and is usually located in the neck, but rare in the mediastinum. This vascular tumor may appear in any portion of mediastinum, but seems to be most common anteriorly. This is a report of one case of congenital mediastinal cystic hygroma in a 25 years old man, especially in the thymic location which was surgically removed successfully with good postoperative result and confirmed histopathologically.

33-year old female was admitted chest surgery department for evaluation of mild chest pain. Chest plain film showed right anterior mediastinal mass and small metastatic daughter mass ipsilateral side. Exploratory thoracotomy was performed 24th Aug. 83 revealed that small nodular parenchymal mass at right middle lobe and large cystic mass at anterior mediastinum which was connected with anterior mediastinal fat. Histological examination confirmed diagnosis as pulmonary hamartoma and thymic cyst individually. We successfully treated these two masses by wedge resection and excision. Although postoperative course was uneventful, the cause and associated relationship between two tumor origin were obscure.

Complete resection of an apicoposterior mediastinal mass is essential due to the mass effect, which exerts pressure on adjacent organs. Recently, the use of minimally invasive surgery has had many advantages. In this report, we describe a case in which a large apicoposterior mediastinal hypervascular mass was managed using a purse-string suture technique during robotic-assisted thoracoscopic surgery (RATS). The patient, a 77-year-old woman, was diagnosed with a 6.2-cm apicoposterior mediastinal hypervascular solid mass originating from the branches of the right subclavian artery. The patient underwent RATS for treatment. To obtain an adequate view of the apex of the thoracic cavity, a needle aspiration was performed, followed by the application of a purse-string suture technique. This was done to reduce the size of the tumor and to prevent catastrophic events such as seeding or spillage of the cystic mass. The mass was histopathologically diagnosed as a schwannoma. The patient was discharged on the first postoperative day without experiencing any complications.
