A 54-year-old male patient was admitted due to dyspnea with chest pain and reddish swelling in the right lteral neck and right upper which developed 2 or 3 days age. He was treated with acupuncture in the neck about one week ago prior to admission. CT scans of the chest showed density of air and abnormal soft tissue which suggested abscess of the anterior mediastinum and subcutaneous tissue. He underwent cervical and mediastinal drainage with closed thoracostomy and antibiotic therapy. Black-pigmente anaerobic nonspore-forming gram-negative bacilli were isolated from the mediastinal pus and were identified as Prevotella intermedia/nigrescens upon performing biochemical tests and API rapid ID 32A (bioMeriux, France) kit. He underwent decortication of the right side because of loculated empyema on 41st postoperative day. He was fully recovered and discharged on the 82nd hospital day. This was thought to be another case of descending necrotizing mediastinitis not caused by peritonsilar abscess but by cellulitis developed after acupuncture. Early deterction of mediastinits and aggressive drainage of mediastinal abscess are important.

Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor in the intervertebral foramen, then have symptoms of back pain,lower extremity tingling sensation. CT scan or MRI demonstrated a Dumbbell-shaped mass density compressing spinal canal, enlargement of the foramen, erosion of bone, and intervertebral widening. We report the analysis of the 18 cases of neurogenic tumors on posterior mediastinum and Dumbbell type tumors are 3 cases among the 18 cases. The neurilemmomas were 12 cases[67%], the ganglioneuroma were 5 cases[28%], and neuroblastoma was one case[5%]. The successful removal was done in all cases, a standard thoracotomy and laminectomy was done in Dumbbell type tumors.There was no postoperative neurological complications.

We performed thoracoscopic resection for diagnosis in 41 year-old-female presenting with multiple pulmonary nodules in both lung fields, which was detected incidentally on routine chest x-ray and followed by additional exmaminations including chest CT scan and percutaneous needle aspiration biopsy under the presumptive diagnosis of metastatic cancer. During thoracoscopy, the result of the frozen section analysis of multiple masses revealed strong evidence of leiomyoma. In her past medical history, she had undergone myomectomy, and hysterectomy, 7 year ago and 10 year ago, respectively. Based on permanent, special staining of specimen, estrogen receptor assay and review of past specimen of uterine myoma the final diagnosis was benign metastasizing leiomyomata from uterine myoma, the report was very uncommon in Korean and English literatures. The patient has been followed up for 2 year without special therapy, such as hormonal therapy.

Primary malignant lymphoma of lung is a very rare disease, only 0.34% of all malignant lymphomas. In our case, a 76 year old male patient had a solitary mass without lympha- denopathy at chest CT scan. He underwent right middle lobectomy through a posterolateral thoracotomy incision. Pathologic study confirmed a diagnosis of malignant lymphoma and chemotherapy was started by an oncologist.

Lipomatosis is a condition containing multiple lipomatous masses.Lipoma is a benign neoplasm composed of adult adipose tissue, and occur most often in the fifth or sixth decade and rarely in the pleura. Pleural lipomas are usually asymptomatic and revealed as an incidental roentgenographic findings. The patient was 59 year-old male and admitted because of dyspnea-on-exertion for 30 years. Chest CT revealed right pleural mass abutting on the chest wall, measuring minus 80 hounsfield units. The mass was resected with calcified pleural plaque and confirmed to be lipomatosis with collagenous fibrosis arising from viserai pleura.

Esophageal leiomyoma is a very rare disease. We present a patient who underwent enucleation of esophageal leiomyoma through a left thoracotomy. The patient was suffered from substernal pain and chest discomfort for 4 months.The esophagogram revealed irregular ovoid smooth filling defect in just proximal portion of G-E junction with the normal mucosal folds. Chest CT demonstrated well-defined, polypoid tumor mass on the anterolateral wall of the distal esophagus. Esophagoscopy revealed normal intact mucosal patterns with swollen hard protruded tumor mass lesion from the just proximal portion of G-E junction. In June, 1993, patient underwent enucleation of esophageal leiomyoma through the left thoracotomy. A horseshoe and spiral shaped, whitish firm tumor mass was noted on the distal esophagus, and the tumor mass was enucleated by blunt dissection carefully. The esophageal leiomyoma was confirmed with histopathological examination. The postoperative course was smooth and uneventful.

Tracheal rupture by a blunt trauma is an uncommon injury, and its clinical presentations are variable. It is a kind of the modern hazard. Herewith, we report a successful management of the tracheal rupture. A 22 year-old female was transferred from other hospital 4 hours after a car crash. Physical examination, simple chest X-ray, Chest CT and fiberoptic bronchoscopy revealed rupture of the membranous portion of the trachea about 5cm in length extending to the right main bronchus. Ruptured membraous portion of the trachea was sutured directly with absorbable suture. Her postoperative course was uneventful, and follow-up fiberoptic bronchoscopy revealed intact membranous portion of the trachea.

Sixty six patients who were operated as lung cancer during the period from Mar. 1991 to Sep. 1993 at the department of Thoracic and cardiovascular surgery, were reviewed retrospectively and the accuracy of regional lymph node in preoperative CT were compared with histopathologlc report obtained from operation. The age ranged from 30 to 72 years old (mean age : 56.5), and 51 patients were male and 15 patients were female. The author analysed the true positive, true negative, false positive and false negative and sensitivity, specificity, positive predictive index, negative predictive index and accuracy of each nodes. The result is that there were differences between seven nodal groups in specificity, sensitivity, positive predictive Index, negative predictive index and accuracy. The range of each nodal group is from 81.7 to 98.3% The nodes of the most poor accuracy are aortopulmonary area and hilar area.

Localized fibrous tumor of the pleura (LFTP) is of submesothelial fibrous origin, which has been called pleural fibroma and has been confused with mesothelioma. We experienced a case of LFTP in a twenty nine year old man. The tumor arose from the right parietal pleura with long stalk. Chest X-ray and CT scan showed a 6$\times$5$\times$4cm well-defined mass in the right costophrenic angle. Wo evidence of metastasis was noted. Exploratory thoracotomy with enbloc excision of 6$\times$5$\times$4cm mass was done. The fine needle aspiration cytology and histopathologic features indicated the tumor to be malignant, and biologic behavior was discussed.

A 45 year old man was admitted for further examination of an abnormal shadow of the right posterior mediastinum. The patient suffered from dysesthesia in the right thoracic wall of dermatome T7. CT scan and MRI revealed that two separate tumors had developed in the right paravertebral area linked to the vertebral canal via an intervertebral foramina. One-stage removal of the tumors were performed safely through the right posterolateral thoracotomy following the resection of the rib head and vertebral pedicle. The tumors were confirmed as histologically neurilemomas. The postoperative course was uneventful.
