Ganglion cell tumors (GCT) are divided into two subtypes : gangliocytoma and ganglioglioma. Intramedullary gangliocytomas are extremely rare. A 20-year-old male patient with pain of neck, who also had a previously known neuroendocrine tumor of lung, was operated for mass found in the cervicomedullary junction with a presumptive diagnosis of metastases. Only partial resection could be performed. Pathological diagnosis had been reported as gangliocytoma. Only ten cases of intramedullary gangliocytoma have been reported in the literature. Although association with scoliosis and Von Recklinghausen;s disease were previously reported in the literature, no gangliocytoma case concomitant with endocrine tumor of lung have been published. Pathological study is the most important diagnostic method for gangliocytomas. Surgical excision is the primary treatment, but difficulty in total surgical tumor resection is the most important problem.

From March 1989 to June 1994, 24 casesof esophageal cancer were treated surgically. Among 24, male was 22 cases, female was 2 cases, and the age ranged from 46 to 75, the mean was 59.8. Symptoms were dysphagia[86.9% , weight loss[65.2% and retrosternal pain or discomfort[47.8% . The tumor was located cervical esophagus in two, upper esophagus in three, middle esophagus in 12 and lower esophagus in 7. Among 24 patients, 22 were curative resection, partial esophagectomy with esophagogastrostomy[18 cases or colon interposition [3 cases , with total esophagectomy with musculocutaneous flap[1 case , with feeding jejunostomy or gastrostomy in two cases.Postoperative complications revealed 10 patients[45.4% , as followed ; pleural effusion and pneumonia in 5, passage disturbance in 4, empyema and wound infection in 3, esophagopleural fistula and sepsis in 2, anastomotic site leakage and respiratory failure in each 1. The operative mortality was 13.6 % [3/22 and causes of death were respiratory failure in 1 case and sepsis in 2 cases.During follow-up work, 8 cases died during follow-up period, mean survival time was 15.2 months in curative resection group. One year survival rate was 55.3% in resected group. Also, cancer recurrence revealed in 1 cases.

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.

An Intramedullary subependymoma of the spinal cord is a rare tumor with only 43 reported cases in the literature. Most of them are reported to be localized within the cervical spinal cord. We report a rare case of a thoracic spine intramedullary subependymoma in a 37-year-old female who presented with back pain and radiating leg pain. Subtotal resection and post-operative radiotherapy were performed. Subependymomas developing in the spinal cord are benign with a low proliferative potential. Complete resection of the tumor appears to be the optimal method for a complete cure. However aggressive surgery may cause severe neurological deficit. Therefore, if severe neurological deficits are expected after complete removal, a partial removal and postoperative radiation therapy is an alternative method for treatment in selected cases. A large-scale randomized study is mandatory to clarify the effectiveness of radiotherapy and to establish the recurrence rate and prognosis with respect to the surgical removal of these tumors.

Mucoepidermoid carcinoma (MEC) is the most common type of malignant neoplasm in the minor salivary gland. The hard palate is a frequently involved site of MEC. The treatment of low-grade MEC on the hard palate is wide local resection with a tumor-free margin. In the present case, the maxillary defect was reconstructed using a buccal fat pad (BFP) flap, followed by application of 4-hexylresorcinol (4HR) ointment for 2 weeks. The grafted BFP successfully covered the tumor resection defect without tension and demonstrated complete re-epithelialization without any complications.

A 45-year old woman with congestive heart failure due to left atrial tumor was operated on. Three tumor masses arising from posterior wall, atrial septum, anterior portion of mitral valve were resected. Pathological diagnosis was malignant fibrous histiocytoma [MFH]. Above one case and sixteen previous reports are reviewed. Eleven cases out of 17 were females. The tumors all originated primarily in the left atrium and 8 had distant metastases. The metastatic sites are lung [4 cases], brain [2 cases], liver, jejunum, cervix and pleura etc. Careful pathologic study is necessary to differentiate the uniformly fatal MFH of the heart from the more common benign atrial myxoma. The treatment modalities are surgical resection, chemotherapy, and radiation therapy & the prognosis of intracardiac MFH is poor. We underwent partial resection of left atrial MFH and obtained symptom relief and patient still alive 7 months post-operatively in state of NYHA class II.

Reconstructive surgery for corrosive esophageal stricture was performed in 392 patients at National Medical Center from 1959 to 1990 Between Jan. 1971 and Dec. 1990, 23 cases were experienced stenotic anastoma of neck after reconstructive surgery for corrosive esophageal stricture. The major procedure of esophageal reconstruction was colon interposition without resection of the strictured esophagus except jejunal interposition in 1 case. There were 12 males % 11 females, and mean age was forty years. The caustic materials were 16[70%] alkali and 7[30%] acid. Half of the cases had hypopharyngeal injury. After reconstructed surgery, dysphagia was developed immediate in 65%, from 2 months to 5 months in 31%, and from years in 4%[1 case]. The complications were anastomatic leakage in 13 cases, anastomatic stenosis in 8 cases, graft gangrene in 1 case, and cancer development in 1 case. The therapeutic procedures were end-to-end anstomolis & partial resection of stenotic anastoma in 18 cases, bourgination in 2 cases, and coin interposition with graft removal in 3 cases. The therapeutic results were excellent in 16 cases, mild discomfort in 3 cases, poor in 3 cases, and death in 1 cases.

Purpose: : To assess the clinic value of application of laparospic ultrasonography (LU) in partial nephrectomy of small renal cell carcinoma. Materials and Methods: From 2007 to 2011, 28 small renal cell carcinoma patients in ou clinic underwent laparoscopic partial nephrectomy with LU. For comparison with preoperative conventional ultrasound and CT, we collected ultrasonic performance of the affected side kidney, renal tumor location, size, echo change, blood supply situation and the relationship with the surrounding tissue. Results: LU could more clearly show the tumor interior structure and blood supply, as well as the relationship with the surrounding tissue. It also can provided doctor assistance with real-time tumor resection, reducing operative complications. Conclusions: LU can clearly show tumor internal structure and blood supply, which is helpful for explicit diagnosis. Moreover, it supplies accurate information for surgeons and assists surgery. Therefore LU has an important guiding value in partial nephrectomy for small renal cell carcinoma.

Verrucous carcinoma is a variant of highly differentiated squamous cell carcinoma and has a predilection for the oral cavity and larynx. It is known to be of good prognosis due to its low regional and distant metastatic potential. Peak incidence is at ages 40-69 while predominantly occuring in males and its association with tobacco smoking has been implicated. The verrucous carcinoma have accordingly been treated by radiotherapy or surgical procedures but there has been considerable controversy regarding the effect of radiotherapy due to the possibility of anaplastic transformation Laser surgery and partial resection are among the commonly used surgical procedures but laser surgery has not yet shown results in improving phonetic abilities. Authors experienced two cases of verrucous carcinoma of the larynx treated by partial laryngectomy and false vocal cord advancement flap who showed no recurrence of disease under stroboscopic examination after two year follow up and when compared to preoperative aerodynamic studies, the expiratory air pressure was decreased and mean air flow rate increased which improved glottal efficiency markedly.

Background: The surgical treatment of pectus carinatum is usually a modified Ravitch operation that consists of complete costal cartilage resection and sternal wedge osteotomy. We tried a simple and easy technique that is resection of only deformed, protruded costal cartilage and pre-sternal compression with using a stainless steel bar and this is done without sternal osteotomy. Therefore, we performed partial cartilage resection and pre-sternal compression with a stainless steel bar and we observed the effects and the efficiency of treatment. Material and Method: From July, 2006 to June, 2008, 10 patients with pectus carinatum underwent our modified technique of pectus carinatum surgery. The effects of surgery and the complications were reviewed. Result: 5 patients with only pectus carinatum underwent our modified technique of pectus carinatum surgery. 5 patients with pectus carinatum and pectus excavatum underwent our modified technique of pectus carinatum surgery and Nuss surgery. The mean patient age was 13.4+3.3 years old. The mean operation time was 137.6+22.9 minutes for the pectus carinatum patients and 234.0+36.5 minutes for the pectus carinatum and pectus excavatum patients. The mean length of hospitalization was 11.8+1.0 days. The Haller pectus index of pectus carinatum was $2.10{\pm}0.21$ preoperatively and this was increased to $2.53{\pm}0.07$ postoperatively. The only complication was simple partial wound disruption in 1 patient. Conclusion: We performed partial cartilage resection and pre-sternal compression with a stainless steel bar in 10 patients with pectus carinatum and its effects were good. Our modified technique of pectus carinatum is easy and simple as compared with the Ravitch operation. But removal of the stainless steel bar has not yet been performed for these patients and long-term follow up is needed to accurately evaluate the. effects of this surgery in many surgical cases.
