Radiological criteria such as smooth, sharply defined interface, obtuse angles between lesion and lung and intimate effect on mediastinal contents were usually used to differentiate mediastinal lesion from parenchymal lung lesion. Recently, we experienced a 60-year-old female presenting with anterior mediastinal mass with cavitation. Grossly it was proven to be peripheral lung cancer adjacent to mediastinum and microscopically it was squamous cell carcinoma. The gross pathological findings of surgical specimen were very well correlated with radiological findings. The unique location such as lung periphery and attachment to mediastinum led us to misdiagnosis of anterior mediastinal mass such as germ-cell tumor and neurogenic tumor.

Complications of the mediastinal tumors and cysts are malignant change, infection, bleeding, local invasion and mass effect to heart, lung and other mediastinal structures. But early surgical excision and proper treatments bring patients to good clinical course and results. Therefore mediastinal tumors and cysts are surgically interesting diseases We report the analysis of the 58 cases of mediastinal tumors and cysts, experienced in the Department of Cardiothoracic Surgery of the Kosin Medical College from July 1979 to June 1989. The results were as follows ; Sex ratio of male to female to female was 1.3: 1. Range of age was from 11 to 64 years and mean age was 34.3 years. The thymomas were 14 cases[24%], the teratomas were 19 cases[33%o], the neurogenic tumors were 10 cases[17%], the cysts were 9 cases[15%], the carcinomas were 3 cases[5%], the thyroid tumor was 1 case[2%], the Castleman’s disease was 1 case[2%] and unclassified tumor was 1 case[2%]. Malignant tumors were 12 cases [21%] of the 58 cases. Most frequent symptom was chest pain and discomfort and relationship of symptom and malignancy was significant. Complete removal of tumor was performed on the 47 cases[92%] and partial excision was 3 cases[6%]. Inoperable cases were treated with anticancer chemotherapy and radiotherapy. Postoperative complications were wound infection, Homer’s syndrome, phrenic nerve palsy, mediastinal hematoma and pleurisy. There was no case of postoperative mortality and good clinical course in surgically completely resected cases.

We have experienced 50 cases of mediastinal tumors and cysts from March, 1979 to August, 1985 at Kyung Hee University Hospital. The results of this cases analysis were as followings; 1. Of all 50 mediastinal tumors and cysts, 26 patients were male and 24 patients were female. There was no sex preference. The age distribution was from 27 months to 64 years, and mean age was 33.5 years old, and also no age preference. 2. The most common mediastinal tumor was benign cysts [12 cases], which comprise 24% of all mediastinal tumors and cysts. The second common mediastinal tumor was teratoma [9 cases-18%], and followed by thymic tumors and tuberculous granuloma [7 cases-14% each], neurogenic tumors [5 cases-10%], and other tumors [10 cases-20%]. 3. The anterior mediastinum was most common tumor location, and followed by middle, superior, and posterior. 4. All 9 teratomas were developed at anterior mediastinum, and 4 of 5 neurogenic tumors were developed at posterior mediastinum. Thymomas were developed at anterior and superior mediastinum. The bronchogenic cysts had no predilection of location. 5. The most common chief complaint at admission was chest pain or discomfort [23 cases-46%], and followed by cough with or without sputum, and exertional dyspnea. Asymptomatic patients were only 7 patients [24%]. 6. Of all 50 cases, 38 cases [76%] received radical tumor resection, 7 mediastinoscopic biopsy, 3 explo thoracotomy and biopsy, and 1 neck mass biopsy. 7. There were 2 hospital deaths, one of which was a patient who suffered malignant thymoma and Myasthenia Gravis. The patient received radical tumor excision, but died at 7th POD. The other patient was a patient with malignant transformation of the benign cystic teratoma. The operative mortality was 4%.

This report is an review of 40 cases of mediastinal tumors which were treated surgically in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1985 to September, 1989. In this series, male to female sex distribution was 1.35:1 with the male predominant. The main clinical manifestations were chest pain and dyspnea, and there was no definitive symptom in 5 cases [12.5 %]. The most common mediastinal tumor was thymoma, 11 cases [27.5 %], and next common mass was germ cell tumor, 9 cases [22.5 %]. The half of these were malignant. In operating, all of the benign masses were removed.

Cystic hygroma is a cystic tumor developed by lymphatic stasis due to congenital blockage of regional lymphatic drainage. It ususally occurs at neck and axilla. However, in some cases of cervical cystic hygroma, cervical portions of the cysts may extend into the mediastinum. We experienced a case of huge cervico-mediastinal cystic tumor in 11 month old girl presenting a large fluctuating neck mass and severe respiratory distress. Surgical resection was done through combined approach of cervical incision and median sternotomy. Pathological diagnosis was confirmed to cervico-mediastinal cystic hygroma.

Two cases of benign mediastinal tumor were treated by complete resection under the video-thoracoscopic guidance. The procedure has been performed on the 2 patients, allowing definite treatment and was less invasive than standard surgical treatment. The 2 patients have been benefited by decreased postoperative pain, reduced scarring of the skin and rapid recovery. Two patients had benign mediastinal tumors; teratodermoid on anterior mediastinum and neurilemmoma on posterior mediastinum. There were no operative death and complication, median hospital stay was four days.

Mediastinal tumors have long fascinated the thoracic surgeon of their variety and unpredictability of iagnosis prior to exploration.We report the analysis of the 34 cases of mediastinal tumors,experenced in the dept.of the Thoracic and Cardiovascular Surgery of the National Medical Center.Between the 1993.9-1992.12. The age distribution was relatively even and the mean age was 35 years old.The thymomas were 16 cases [ 47% ].the lipoma were 4 cases [12%].the germ cell tumors were 7 cases [20%].the neurogenic tumors were 3 cases [8%].Histologically analysised .The malignant tumors were 16 cases [17.6%] in classified by hisotlogical types.the tumor size,location,and the clinical manifestation are presented.The successful removal was done in 28 cases [ 100%] among 28 cases of benign mediastinal tumors. Among the 6 cases of malignancy mediastinal tumors, the surgical intervention had done in 5 cases [ 83%] and inoperatable cases were 1 case [16.6%].There was no operative death.

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.

Posterior mediastinal goiter extending to carotid sheath posteriorly is rare repoted case. Recently we experienced huge posterior mediastinal goiter with compressin of trachea in 57-year old male, The patient that complained of dyspnea referred to our hospital for further evaluation of mediasitnal tumor. We confirmed huge secondary posterior mediastinal intrathoracic goiter with diagnostic methods following by chest X-ray, thyroid scan, chest CT, and CT guided fine needle aspiration biopsy in this patient, and performed operation for excision Exision of posterior mediasitnal goiter performed through initial transeverse cervical incision and additional median sternotomy, and the mass removed completely without any complications. The postoperative course were uneventful.

Posterior mediastinal goiter extending to carotid sheath posteriorly is rare. Recently we experienced two cases of posterior mediastinal goiter presenting dyspnea due to tracheal compression. The one was a 48-year-old female with mediastinal tumor shadow on chest roentgenogram . The other was a 54-year-old female with palpable mass on neck and huge mediastinal mass. These masses were resected completely through the right posterolateral thoracotomy and median sternotomy respectively. The postoperative courses were uneventful.
