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.

We experienced one case of immature teratoma at anterior mediastinum. the patient was Syears old female whose complain were cough and chest pain. Chest film showed mass density St the lower half of the Rt chest. Chest CT showed inhomogenous mass which have some calcified area. At the time of operation, 12x10x13cm sized mass have smooth surface and its stump elongated to the thymus. a-FP level, preoperative 22.5ng/ml, was decreased to 9.7ng/ml after operation. Postoperative adjuvant chemotherapy was performed with Vinblastin, Bleomycin and Cisplatin combination. The patient had an uneventful postoperative or postchemotherapy course and was discharged in a good condition.

Calcified right ventricular thrombi are very rare.One case of large clacified thrombus in right ventricle being seen in a 65-year old man, is presented. He had dyspnea and generalized edema.The chest film showed a large calcified mass in cardiac shadow especially in lateral view.On echocardiography and chest computed tomography, large calcified mass density occupied nearly entire right ventricular outflow tract.The mass removal was performed through right ventriculotomny.The mass was whitish, stony hard, measured 4 cm x 4.5 cm x 8 cm, tightly attached to right ventricular infundibular septum and ventriculoinfundibular fold.

The lipomatous of the mediastinum are fairly uncommon tumors. Since 1971, two patients with proven mediastinal lipoma and one primary liposarcoma of the mediastinum have been treated at the Seoul National University Hospital. This report reviews our experience with the review of literature. Case 1.: A 3 year old body revealed a huge round homogenous mass density in the posterior mediastinum in routine chest X-ray. The tumor mass, lipoma, was successfully removed and postoperative course was uneventful. Cases 2.: An asymptomatic 24 year old male was operated on with the preoperative diagnosis of mediastinal lipoma. His preoperative chest X-ray and CT films showed a huge anterior to middle mediastinal tumor, right, with fat density. There is no postoperative problem after successful removal of the tumor mass. Case 3. : A 24 year old female was hospitalized with the complaints of cough and chest pain. A mediastinal mass was removed, which proved to be a liposarcoma on pathologic examination. About one year later, she was found to have recurrent liposarcoma in the right chest area at the OPD follow-up. She was lost to follow-up since then.

Ewing sarcomas constitute a group of small, round, blue cell tumors of the bone and soft tissue. Extraskeletal Ewing sarcoma (EES) is a rare malignant neoplasm that arises from soft tissues, and it usually affects children and young adults. EES of the thoracopulmonary region commonly presents with a palpable mass or pain. Although rarely reported, EES affecting the anterior chest wall may present as a breast mass. We report a case of EES arising from the chest wall and manifesting as a palpable breast mass in a 22-year-old woman. The large mass was initially misdiagnosed as a breast origin mass on ultrasonography, but subsequent CT and MRI showed that the mass originated from the chest wall. Radiologists should be aware of the imaging findings of EES, and they should understand that chest wall lesions may be clinically confused as breast lesions.

Isolated bronchogenic cysts of the diaphragm are rare abnormalities. They are usually asymptomatic unless secondarily infected or large enough to cause compression of vital structures. The patient was a 31-year-old man and had no symptoms except mild postprandial epigastric discomfort. The chest X-ray and chest C-T examination revealed a mediastinal mass at the left cardio-vertebro-phrenic angle. We performed the operation under the impression of solid mass at mediastinum. We revealed that the mass was bronchogenic cyst in diaphragm. Therefore we report this case with review of literatures.

The incidence of chest wall tumor is rare than those of other portions of the body. The chest wall tumors need special attention about their diagnosis and management than other tumors. From March, 1985 to September, 1994, 33 patients with chest wall tumor underwent surgical treatment, and those were consisted of 28 benign tumors and 5 malignant tumors arising from soft tissue, rib and sternum.Benign tumors were included 11 lipoma, 4 cysticercosis, 2 chondroma and 1 each of fibroma, dermatofibroma, osteochondroma, fibrous dysplasia and hemangioma,and 6 other cases. Malignant chest wall tumors were included 2 metastatic carcinoma,1 each of giant cell tumor, chondrosarcoma and epithelioid sarcoma.Sex ratio of male to female was 1.5:1, and the range of age was 16 to 72 years,and the mean age was about 40 years. Clinical manifestations of chest wall tumor were palpable mass[55% , pain[21% ,tender mass[9% , growing mass[9% and asymptomatic[9% .The all cases were treated surgically, the results were as follows:Local excision 16 cases, wide resection 12 cases, wide resection with chemotherapy 3 cases, each one case of wide resection with radiotherapy and wide resection with chest wall reconstruction.

We experienced thymolipoma which is a rare benign mediastinal tumor, an admixture of atrophic thymic tissue and matured adipose tissue. The patient was, 13 years old boy, admitted due to anterior mediastinal mass on routine chest X-ray and complained of mild exertional dyspnea. The physical examination revealed percussion dullness, decreased breathing sound at right anterior hemithorax. The chest PA and lateral views showed both paracardiac mass density and obliteration of retrosternal clear space. The chest CT Scan showed tubular structure containing of thymic tissue and enhanced fatty tissue, suggested thymolipoma. Operation was performed under the impression of thymolipoma. Through median sternotomy, the huge mass was resected. Grossly, the mass was yellowish fatty colored, measured 15X12X10cm, weighed 600gm. Light microscopic examination showed that thymic tissue containing of Hassal`s corpuscles were surrounded by matured adipose tissue, as the characteristic finding of thymolipoma. The postoperative course was uneventful.

The gastroesophageal cyst is rare variety of benign developmental cysts in the mediastinum and it arises from sequestrations of nodules of forgut in the developing embryo.The patient was 23 year old man with complaint of right chest pain. Simple chest X-ray and chest CT scan showed a huge homogeneous cystic mass in the posterior mediastinum. The resected cystic mass showed combining of portion of esophagus and stomach.

The author reviewed 10 patients of chest wall tumors which were operated during 7 years, from 1970 to 1976, in Department of Thoracic and Cardiovascular Surgery in Chonnam University Hospital. Benign tumors were 6 patients, malignant tumors were 2 patients and metastatic tumors were 2 patients. Benign tumors were more than malignant tumors, but total cases were small, so, statistical analysis was not enough. Specific symptoms of chest wall tumor were swelling due to mass and pain. All cases had swelling due to mass and 4 cases [40%] had pain. Dyspnea was noted in metastatic tumors. The review of the literatures was also done.
