The author have diagnosed and treated the mixed tumor having been originated from submaxillary gland in 43 years old korean woman. The mixed tumor was enucleated by means of total resection of tumor mass and the involved submaxillary gland. The enucleated mixed tumor mass was 6×6, 5×6.7Cm. in size, and the postoperative prognosis was excellent good, and I convinced that the lesion had been completely healed.

Diagnosis of gastric subepithelial tumors (SETs) is sometimes difficult with conventional endoscopy or tissue sampling with standard biopsy, so non-invasive imaging modalities such as endoscopic ultrasound (EUS) and computed tomography are used to evaluate the characteristics of SETs features (size, location, originating layer, echogenicity, shape). However imaging modalities alone is not able to distinguish among all types of SETs, so histology is the gold standard for obtaining the final diagnosis. For tissue sampling, mucosal cutting biopsy and mucosal incision-assisted biopsy and EUS-guided fine-needle aspiration or biopsy (EUS-FNA or EUS-FNB) is commonly recommended. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are used for resection of SETs involving the mucosal and superficial submucosal layers, could not treat adequately and safely the SETs involving the deep mucosa and muscularis propria. Submucosal tunneling endoscopic resection (STER) and endoscopic full-thickness resection (EFTR) is used as a therapeutic option for the treatment of SETs with the development of reliable endoscopic closure techniques and tools.

A clinical analysis was performed on 11 cases of metastatic lung cancer experienced at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital during the 15 year period from 1970 to 1984. Of the 1lpatients of metastatic lung cancer, 4 patients were male and 7 patients were female and the age ranged from 27 years to 60 years old with the average of 38.8 years old. The sites of primary tumor were uterus and ovary in 5 patients, breast in 2, sarcoma in 2, rectum in 1 and testis in l.\ulcorner Tumor free intervals in each patients were as followed; unrecognition of primary site in 2 patients, simultaneous discovery of primary tumor and metastasis in 3, 14 months in 1, 4 years in 4 and 5 years in Twelve thoracotomies were performed in 11 patients and performed procedures were as followed; pneumonectomy in 1 patient, lobectomy in 7, wedge resection in 2, decortication and wedge resection in 1 and biopsy only in 1. Of the 11 patients, 4 patients died within one year after operation, 2 patients died within 2 years and 2 patients are alive over 5 years after operations. Other 3 patients are alive 2 months, 4 months and 9 months after operation at present.

The authors report a case of 42-year-old woman with an intraventricular tumor in the trigone of the left lateral ventricle. The first operation achieved a microscopically complete resection. The tumor was histologically atypical meningioma. After 26 months, there were recurrences of intraventricular meningioma. Complete resection of the tumor and adjuvant radiation therapy were performed, and the histological diagnosis was malignant meningioma. Sixteen months after the second operation, spinal metastasis in cervicolumbar lesion was diagnosed and a subtotal removal of cervical intradural extramedullary mass was performed. We describe an unusual case of intraventricular malignant meningioma with cerebrospinal fluid-disseminated spinal metastases with review of the clinical courses of previous reports.

Cystic Meningiomas are rare tumor. There is a clear prevalance in infants, according for $10{\sim}19%$ of all intracranial meningiomas in this age group, compared with only $2{\sim}4%$ in adults. But, reports of cystic meningioma have been increased in frequency since the introduction of computed tomography[CT] and magnetic resonance image[MRI]. Authors report two cases of cystic meningioma in adults. Radiological finding showed extraaxial mass with cystic component. Authors performed total surgical resection of the tumor mass and of the entire cystic component with cystic wall in both patients. Postoperative histopathological diagnosis of the tumor mass was a transitional meningioma in both patients. Both patients showed favorable prognosis and no recurrence findings in follow up MRI.

Medulloblastoma is a common pediatric tumor typically diagnosed before the age of fifteen. Initial therapy includes surgical resection and radiation of the entire neuro-axis. Recurrence is common and typically occurs within 2 years of initial diagnosis. Those fitting Collin's Law is considered tumor-free. We report a case of single supratentorial recurrence 13 years after initial diagnosis. Here we present a 22 year old male presenting 13 years after initial diagnosis with isolated septum pellucidum recurrence. He underwent complete resection of the tumor. Medulloblastoma is a common in the pediatric population. Late recurrence to the ventricular system is uncommon. Long term follow-up is recommended in these patients.

Spinal angiolipomas are rare lesions usually found in the epidural space of the thoracic spine. The infiltrating type of spinal angiolipomas is extremely rare. This report presents the case and reviews the related literature. A 58-year-old man was presented with a 7-month history of progressive weakness and sensory change of lower extremities. Magnetic resonance images showed a well-enhanced mass infiltrating the vertebral foramen at the T4-5 level. Resection of the tumor was performed. Histological study revealed the tumor as an angiolipoma. The patient was relieved from symptoms after tumor resection.

The authors present a case of 68-year-old woman who underwent resection of a metastatic adenocarcinoma in the left parietooccipital area. The intraoperative course was uneventful; however, after closure of the scalp incision, increased bleeding from the suture line was noted. A computerized tomography scan that was performed immediately after operation revealed acute epidural hemorrhage with mass effect under the bone flap. The patient developed disseminated intravascular coagulation and immediate re-exploration was performed. This patient was successfully treated owing to early recognition of the condition and immediate treatment with transfusion. Neurosurgeons should be alert that hypercoagulabe state is common in cancer patients and consumptive coagulopathy can occur after resection of metastatic brain tumor.

Tracheal stenosis is being encountered more frequently as ventilatory support and cuffed tubes are increasingly used for treatment of respiratory failure. We experienced 13 cases of tracheal stenosis treated surgically at department of Thoracic and Cardiovascular Surgery, school of medicine, Kyung Hee university during the 4 years. The causes of tracheal stenosis were prolonged endotracheal intubation 5 cases, tracheostomy 3 cases, tracheal tumor 2 cases, thyroid tumor 1 case and congenital double aortic arch 1 case. The methods used to manage the tracheal stenosis were tracheal resection % end to end anastomosis 8 cases, 2 cases of subglottic stenosis were underwent primary laryngotracheal anastomosis, Lt. aortic arch division 1 case, and stent insertion 2 cases. In two cases, who had 6 cm in length of tracheal stenosis, we were underwent tracheal resection k end to end anastomosis with supralaryngeal release procedure. Postoperative courses were uneventful except one case with tracheal tumor.

원발성 심장종양은 드물며 원발성 악성 심장종양은 더 드물지만 이중 맥관육종은 다른 종양보다는 흔한 편이다. 하지만 수술적 절제가 어려운 것으로 알려져 있는데 이는 환자의 증세가 비특이적이며 진단시 이미 종양의 침범이 진전된 상태가 대부분이기 때문이다. 보고자는 15세 남자에서 수술중 시행한 조직학 검사에서 원발성 심장 맥관육종을 확진하고 우심방을 거의 막고 있는 종양을 제거하였다. 환자는 수술후 15일후에 특별한 문제없이 퇴원하였다.
