We experienced a case of benign clear cell tumor of the lung. It is a rare and very unusual pulmonary neoplasm. Only 40 cases have been reported in the foreign literatures, but this is the 2nd case report in Korea. A 43 year old man who revealed a coin lesion in the chest X-ray at the health screening, underwent resection of the right lower lobe Pathologically the tumor ce ls have a clear cytoplasm due to abundant glycogen in the histochemical and electron microscopical studies.

장막내의 고립성 섬유성 종양은 드물며 대부분 장측 또는 벽측 흉막에서 발생하지만 종격동, 심막, 복막, 폐실질 , 안과 그리고 뇌척수막에서도 발생하기도 한다. 이 종양은 다양성으로 인하여 진단하는데 어려움이 있으며, 특히 종격동이나 흉부 외의 장소에서 발생하는 경우에는 더욱 그러하다. 이 종양의 임상적 양상을 예측하기 어려우며 조직학적으로 양성의 소견을 보이면서, 임상적으로는 악성의 양상을 띠기도 한다. 악성의 임상양상을 보이는 경우는 약 13∼23% 정도로 보고되고 있다. 저자는 53세의 여자 환자에서 종격동의 고립성 섬유성 조양을 수술한 후, 4차례 재발한 드문 증례를 수술 치험하였기에, 문헌 고찰과 함께 보고하는 바이다.

Papillary fibroelastoma is a rare benign tumor of the heart. A 21-year-old man presented with dyspnea on exertion and echocardiogram showed a small round mass attached to the anterolateral papillary muscle. After excision of the mass, including anterior papillary muscle, chordae tendinae, and anterior leaflet, he underwent mitral valve re-placement with a mechanical valve. He was discharged on anticoagulant therapy without further problems.

지방모세포종은 태생기 지방조직에서 기원하는 드문 양성종양으로 대부분 소아기에 발생하는데 이 종양의 약 70%는 사지에서 나타나고 간혹 다른 부위에서 보고되기도 한다. 저자들은 좌측 후종격동과 좌측 쇄골상부에 양성 지방모세포종을 보인 3세된 남아를 치험한바 있다. CT 소견상 지방을 함유한 종괴가 정상적인 흉강내 구조물을 누르고 있었고, 쇄골상부 및 종격동으로부터 합병증없이 절제되었다. 종괴는 황색을 띠었으며, 병리조직검사상 지방모세포종으로 진단되었다.

Endoscopic removal is acceptable for the treatment of endotracheal/endobronchial mass, because it is less invasive in high-risk patients and a conservative procedure for benign tumors. Two benign tumors in the lumen of the trachea (pure lipoma) and in the intermediate bronchus (hamartoma) were completely eradicated by our procedures, which involved diathermic snaring and residual mass removal with biopsy forceps under the guidance of fiberoptic bronchoscopy. No tumor recurrence was evident after extended follow-up (6 years for endotracheal lipoma and 2.5 years for endobroncheal hamartoma). Our method is safe and less invasive for the patient and provides the surgeon with better view during procedure.

Cardiac myxoma is the most common benign tumor of the heart. However, low incidence of recurrence and metastasis has been reported. A 49-year-old female patient was admitted in the hospital due to sudden onset of left side weakness. Magnetic resonance imaging (MRI) of brain showed multifocal areas of diffusion restriction on diffusion weighted images. Echocardiography was performed to evaluate the cause of embolic brain infarction and cardiac myxoma was found in the left atrium. The patient underwent complete excision of the mass. One year later, the patient was readmitted with symptoms of dysarthria. Brain MRI showed newly developed multiple hemorrhagic metastatic lesions. The patient underwent radiotherapy of the metastatic lesions. Although rare, cardiac myxoma can cause delayed metastasis. We report a rare case of delayed multiple cerebral metastases from the completely resected cardiac myxoma.

Esophageal schwannoma is very rare and almost of all cases are diagnosed as esophageal submucosal tumor preoperatively. Final diagnosis is made by postoperative immunohistochemical (IHC) staining of the surgical specimen. We experienced two cases of esophageal submucosal tumor, one was 63 year old female suffering from three months of dysphagia and another was 39 year old female complaining of two months of intermittent dysphagia. Two esophageal tumors were completely removed by esophagectomy and enucleation through right thoracotomy respectively. Postoperative IHC staining demonstrated S-100 positive without mitotic figures and confirmative diagnosed was made as benign esopphageal schwannoma.

심장에서 발생하는 모셀혈관종은 극히 드문 양성 종양이다. 본원에서는 호흡곤란을 주소로 내원한 13세 남자 환자에서,심포음파상 중등도의 혈류 폐쇄를 초래하는 우심실내 종괴를 확인한 후, 우심방을 통해 완전 절제하여 조직검사상 모세 혈관종을 발견하였기에 문헌고찰과 더불어 증례보고하는 바이다.

Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

Localized fibrous tumor of the pleura is a rare condition. Most follow a benign course and they are round as an incidental finding during routine chest X-ray. A small proportion of these tumors are malignant and have characteristic clinical and histopathological features. In this paper, we report three cases of localized fibrous tumors of the pleura, one malignant associated with asymptomatic hypoglycemia, the others benign. In a malignant case, the tumor was reseated through thoracotomy and the hypoglycemia was relieved immediately. In two benign cases, tumors on small pedicles were resected using video-assisted thoracic surgical technique.
