We describe the case of a 58-year-old woman who has coexisting intrapulmonary and mediastinal leiomyomas. Initially, she was seen with a single mass in the right lower hilar area in a simple chest roentgenogram. But computed tomography demonstrated another mass in the right posterior mediastinum. Microscopic examination and immunohistochemical staining of the resected specimens showed the characteristics of the leiomyoma.

Intrapulmonary teratoma is rare : only 30 cases have been reported in the world literature. We had experienced a case of benign intrapulmonary teratoma originated from anterior mediastinum associated with broncho-tumorous fistula, which was treated with En bloc removal of tumor and right middle lobectomy. Post-operative course was not eventful.

Lipoma is a circumscribed mesenchymal tumor originating from the adipose tissue. The lesion is usually small and asymptomatic. The most common location is in the neck region, however, lipoma can be found in the mediastinum in rare occasions. Although lipoma reach to the large proportions in the mediastinum, it rarely compresses the neurovascular structure. We present a case of a 58-year-old man, in which a hourglass-type cervicomediastinal lipoma produced Horner's syndrome with voice change. The man presented a swelling at the right side of his neck, ptosis and anhidrosis on the right side of his face, and right chest discomfort. After the removal of the mass, all the symptoms which had been provoked by compression, as well as Horner's syndrome and hoarseness, nearly disappeared.

Thymic carcinoid tumor is a rare mediastinal tumor, which was firstly described by Rosai and Higa in 1972. A carcinoid tumor of the thymus has recently been regarded as a distinct tumor from thymoma, and is probably Kultschizky cell origin. The pathologic diagnosis of thymic carcinoid is made from findings from light microscopy, immunohistochemical studies and electron microscopy. About 50% of thymic carcinoids were seen with endocrinopathies. Recurrences and extrathoracic metastasis are characteristics of thymic carcinoids. Surgical removal of the intial and tumor recurred are considered to be the most effective treatment today. However, the role of the adjuvant radiotherapy and the chemotherapy is still uncertain. Herein we report a case of thymic carcinoid tumor, which was confirmed by operation and pathologic study.

Thymolipoma is a rare benign tumor of anterior mediastinum. Most patients are asymptomatic with incidental finding of the tumor during a diagnostic workup of other medical problems. We present a case of 13-year-old girl with anterior mediastinal thymolipoma, surgically removed after an incidental diagnosis.

Epithelioid hemangioendothelioma (EHE) is a low-grade malignant vascular neoplasm that can occur anywhere in the body. EHE has a low annual incidence (0.38/10⁶) and prevalence (< 1/10⁶), and primary mediastinal EHE is exceedingly rare. We report a case of EHE in a 53-year-old female which manifested as an incidentally discovered mass in the right paratracheal region. In this report, authors describe the pathological and radiological findings of primary mediastinal EHE invading the superior vena cava in the right paratracheal area.

Chordomas are slowly growing and rare malignant tumors arising from the remnants of the notochord. Furthermore, intrathoracic chordomas presenting as a posterior mediastinal tumor account for only 1∼2％ of all reported chordomas. Incomplete resection of these tumors can lead to local recurrence, distant metastasis and result in a poor outcome, but complete remission can be expected with complete resection and adjuvant radiotherapy. We report a case of thoracic chordoma presenting as a posterior mediastinal tumor which was successfully treated with complete resection and adjuvant radiotherapy without recurrence and distant metastasis for 2 years.

This report is a review of 98 cases of the primary mediastinal tumors which are treated in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1985 to February, 1993 and divided two groups. One group is from January, 1985 to January, 1989 and named it Group 1[G1]. Another group is from February, 1989 to February, 1993 and named it Group 2[G2]. Chest pain is the most common clinical manifestation in the two groups. The common mediastinal tumors are teratoma 11 cases[29.7%], neurogenic tumor 7 cases[18.9%], thymoma 6 cases[16.2%], primary cyst 3 cases[8.1%] in Group 1 and thymoma 16 cases[26.2%], teratoma 15 cases[24.6%], neurogenic tumor 9 cases[14.8%], primary cyst 9 cases[14.8%] in Group 2. Therefore this result shows that the incidence of thymoma is increased in group 2. In benign tumors, the subjective symptoms are 64.3% in group 1 and 63.6% in group 2. In malignant tumors, they are 100% in group 1 and 82.4% in group 2. this result shows that asymptomatic malignant tumors are increased in group 2. The successful excision is done in all of the 71 benign tumors except one. In malignant tumors, the complete surgical excision is increased from 11.1% in group 1 to 41.2% in group 2.

Mediastinal hemangioma is a rare tumor and only few cases have been reported in the literatures. We have experienced one case of cavernous hemangioma occuring at the superior vena cana. The patient was a thrity-five year old female with no specific symtoms except palpable cystic mass in the right cervical area. A routine chest radiography showed an upper mediastinal mass. Computed Tomography showed about 4$\times$5 cm sized cystic mass communicating to the superior vena cava 2 cm above of the veno-atrial junction. After the evaluation, surgical excision was performed and the pathologic diagnosis was confirmed to cavernous hemangioma. Postoperative course was uneventful and the patient has been followed up without any problems.

Generally early surgical extirpation is considered to be beneficial for the treatment of mediastinal tumors and prevention of its complication. The review of the clinical course, histopathologic characteristics and current diagnostic and treatment modalities will help us to decide when to treat and how to treat mediastinal tumors. For this purpose clinical analysis of the 42 patients who were surgically treated from July 1984 to August 1993 in the Chung Ang University Hospital is done in this report. There were 24 males and 18 females[1.3:1], and their age ranged from 1 year to 75 years. Nonspecific symptoms such as chest pain, cough and dyspnea were the most frequently encountered symptoms. Asymptomatic patients were relatively common[21.4%]. The tumors were found most frequently in the posterior mediastinum[45.2%]. Anterior mediastinum was the next and middle and upper mediastinum showed relatively rare occurrence of the tumor. Neurogenic tumor was the most common histopathologic type . Germ cell tumor, benign cyst and thymoma followed it. Curative resection was possible in 27 patients[64%], partial resection in 6 patients[14.3%]and just open biopsy in 7 patients[16.7%]. There was no early operative mortality. Postoperative complications were occurred in 5 patients[11.9%] and most of them were not serious.
