Granular Cell Tumors(GCT) were originally described as myoblastic myomas. This tumor is believed to originate from Schwann cells based on subsequent scientific investigations. Although it usually appears in the head and neck, it can also appear in other organs as well. Endobronchial granular cell tumors are rather rare and should be differentiated from other common endobronchial diseases such as bronchogenic carcinoma and endobronchial tuberculosis, especially. A case of a patient with an extremely rare condition of endobronchial granular cell tumor concurrent with malignant mediastinal tumor is reported.

We experenced 18 patients with surgically treated thymoma from January 1986 to December 1993. There were 13 male and 5 female ranged from 23 to 69 years of age. Among them Myasthenia gravis was present in 8 patients (44%) The predominant cell type was lymphocytic(11 patients), followed by epithelial (3) and mixed (4), and had no value in predicting prognosis. Treatment consisted of complete resection in 15 patients, partial resection in 2 patients and 1 patient was performed biopsy. Only, and then adjuvant radiation therapy was done in 7 patients and 3 patients needed adjuvant chemotherapy. Invasion of the adjacent tissue in thymoma was the most improtant prognostic value. There were 6 non-invasive tumors and 12 invasive tumors. Two patients with invasive thymomas resulted in death and one of 6 patients with non-invasive thymomas died during follow up ranged from 25 day to 60 months. The causes of death were myasthenic crisis in 1 patient, C. N. S. problem in 1 patient and pulmonary & mediastinal metastasis in 1 patient.

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.

We have experienced 27 cases of primary medistinal tumors and cyst from April, 1986 to April 1996. At Masan Samsung General Hospital. The results of the anslysed were as follows 1. Of 27 medistinal tumors and c,pests, 9 patients were male and 18 patients were female(m : f= 1 : 2) 2. The most common chief complaint was chest discomfort or pain(8 cases 30 %) and 17 patients(63%) were asymptomatic. 3. The most common primary medistinal tumor was Neurogenic tumor in 9 cases(33 %) followed by Thymoma in 7 cases(26 %), teratoma in 6 cases(22 %) 4. The incidence of malignancy of all case was 3 cases(11 %), all cases were symptomatic and the most common malignancy was malig. thymoma(3 cases,43 %) 5. The anterior mediastinum was the most common tumor location with 15 cases(56 %) followed by posterior 11(41 %) and middle mediastinum 1(4 %). Anterior mediastinum tumors were predominantly thymomas and teratoma and posterior mediastinal tumors were neurogenic tumors 6. Complete removal of tumor was achieved in 26 cases(96 %) and open biopsy was done on 1 case 7. Postoperative complications were continued lumbar shunt drainage in 1 case and wound infection in 1 case 8. There was no case of postoperative mortality and good clinical course in surgically completely rejected cases

Mediastinal teratoma is one of the most common lesions found in the anterior mediastinum, accounting for $8\sim13%$ of all mediastinal tumors. This tumor is incidentally detected by routine chest roentgengography, but pericardial perforation or pleural effusion occurs rarely. In our patient cardiac tamponade was developed due to anterior chest wall contusion, we confirmed the anterior mediastinal tumor. Vital signs were stabilized after the pericardiocentesis, and the patient underwent the tumor resection in the anterior mediastinum for a definite treatment. On histologic examination, the tumor revealed cystic structures composed of mature squamous epithelium, pilosebaceous glands, mature fat tissue, gastrointestinal mucosa, respiratory epithelium, and pancreatic tissues.

An occurrence of hemangioma in the mediastinum is a very rare, accounting for less than 0.5% of mediastinal tumors. Capillary hemangiomas and cavernous hemangiomas consists of over 90% of mediastinal hemangiomas. However, venous hemangioma has never been reported in South Korea and has also very rarely been reported worldwide. We found mediastinal solid mass, as an incidental finding during a follow-up chest CT scan of a 44-year-old female patient who had undergone colon cancer surgery. We performed a mediastinoscopic biopsy. We did a thoracotomy to remove this mass because hemorrhage and found a totally resected venous hemangioma.

Background: The presence of infiltrated mediastinal lymph nodes is a crucial factor for the prognosis of lung cancer. The aim of our study is to investigate the pattern of metastatic non-small cell lung cancer that spreads to the mediastinal lymph nodes, in relation to the primary tumor site, in patients who underwent major lung resection with complete mediastinal lymph node dissection. Material and Method: We retrospectively. studies 293 consecutive patients [mean age $63.0{\pm}8.3$ years (range $37{\sim}88$) and 220 males (75.1%)] who underwent major lung resection due to non-small cell lung cancer from January 1998 to December 2005. The primary tumor and lymph node status was classified according to the international TNM staging system reported by Mountain. The histologic type of the tumors was determined according to the WHO classification. Fisher's exact test was used; otherwise the chi-square test of independence was employed. A p-value < 0.05 was considered significant. Result: Lobectomy was carried out in 180 patients, bilobectomy in 50, sleeve lobectomy in 10 and pnemonectomy in 53. The pathologic report revealed 124 adenocarcinomas, 138 squamous-cell tumors, 14 adenosquamous tumors, 1 carcinoid tumor, 8 large cell carcinomas, 1 carcinosarcoma, 2 mucoepidermoid carcinomas and 5 undifferentiated tumors. The TNM stage was IA in 51 patients, IB in 98, IIB in 41, IIIA in 71, IIIB in 61 and IV in 6. 25.9 % of the 79 patients had N2 tumor. Most common infiltrated mediastinal lymph node was level No.4 in the right upper lobe, level No. 4 and 5 in the left upper lobe and level No. 7 in the other lobes, but no statistically significant difference was observed. Thirty-six patients (12.3%) presented with skip metastasis to the mediastinum. Conclusion: Mediastinal lymph node dissection is necessary for accurately determining the pTNM stage. It seems that there is no definite way that non-small cell lung cancer spreads to the lymphatics, in relation to the location of the primary cancer. Further, skip metastasis to the mediastinal lymph nodes was present in 12.3% of our patients.

Approximately 9.8% of neurogenic tumors of the mediastinum extend into the spinal column so that the composite neoplastic mass was dumbbell shaped. We experienced three patients confirmed by Dumbbell shaped mediastinal tumor radiologically and tried surgical resection by posterolateral thoracotomy only corpectomy and costotransversectomy was performed simultaneously in three patients and interbody fusion in two. In one patient the diagnosis was liposarcoma and in 1 neuroblastoma and in 1 neurilemmoma. then followed by radiation theraphy in case I and radiation and chemotheraphy in case II. All three cases showed satisfactory results clinically and radiographically.

Cystic hygroma is a benign tumor of lymphatic origin encountering most frequently in young children, and composed of softly fluctuated mono or multilocular cystic masses which developed from embryonic outpouching of the venous system. The majority of these tumors are found at the anterolateral neck region particularly posterior .triangle, and occasionaly axilla, mesentery and spleen etc. In the mediastinum, the incidence of hygroma is very rare and also of mediastinal neoplasms. Recently, we have experienced 2 cases of mediastinal cystic hygroma connected up lateral neck and to anterior chest wall respectively, which were surgically removed successfully and confirmed histopathologically. Authors present the cases and discussion with a brief review of the relevant literatures.

A 71-year-old male patient visited Yeungnam University Hospital with abnormal chest computed tomography (CT) findings. Chest CT revealed multiple lung nodules and a posterior mediastinal tumor, the diagnosis of which was confirmed surgically. Magnetic resonance imaging (MRI) of the abdomen showed multiple small nodules, which were diagnosed as cavernous hemangioma in the liver based on the pathology results of the mediastinal and lung masses in combination with MRI findings. Cavernous hemangiomas are benign tumors that can occur throughout the body, mainly in the skin and subcutaneous tissue. The liver is the most common internal organ containing hemangiomas, whereas they are very rarely found in the lungs or mediastinum.
