Hemangioma in the esophagus is an uncommon tumor. There have only been about 30 cases reported in the world literatures. It occurs predominantly in men and although majority are asymptomatic, may cause bleeding and dysphagia. Hemangioma in the esophagus was diagnosed with a barium swallowed esophagography and endoscopy. The main treatment modes recommended are surgery and endoscopic resection. We experienced one case of cav ernous hemangioma occurring at the distal esophagus. The patient was a forty-six year old male with dysphagia and indigestion. Barium esophagogram showed a filling defect at the distal portion. Esophagoscopy showed a bluish polypoid mass. Surgical resection was per formed and the pathologic diagnosis was confirmed as cavernous hemangioma. Postoperative course was uneventful and the patient had been followed up without any problems.

Purpose: Endoscopic incision and submucosal dissection (EISD) is a technique that is being implemented for the resection of gastric adenomas and early gastric cancer (EGC). Since EISD requires a high degree of skill and experience, and due to its association with a moderate risk of gastrointestinal bleeding, its use has been limited. The objective of this study is to investigate the clinical benefits of EISD based upon clinical data on the EISD procedure. Materials and Methods: This study was conducted at Soonchunhyang University Hospital and it included 179 gastric adenoma and early gastric carcinoma lesions from 164 patients who had undergone an EISD from February 2003 to May 2005. Results: Among the total of 179 lesions, the distributions of EGC and adenomas were 70.3% (126/179) and 23.4% (42/179) respectively. The sizes of lesions were divided into 10 mm or less, $11{\sim}20\;mm,\;21{\sim}30\;mm$ and greater than 31 mm and each rates are 10.0% (18/179), 46.3% (83/179), 30% (50/179) and 15.0% (28/179). Among 120 cases which could be measured depth of lesion in according to pathologic findings, m1 (0.8%, 1/120), m2 (38.3%, 46/120), m3 (25%, 57/120), sm1 (11.7%, 14/120), sm2 (1.6%, 2/120) were diagnosed as early stages of gastric cancer. The complete resection rate was 85.2% (150/176) and en-bloc resection rate was 96.0% (169/176). Complications as such as perforation and bleeding developed in 4.4%(8/179) and 21.2% (38/179), respectively. Conclusion: EISD is an effective in the endoscopic treatment for gastric adenoma and early gastric cancers. However, further evaluation of this method and long-term follow-up will be necessary for an evaluation of the recurrence rate after resection of a tumor.

Purpose: This study aimed to provide, as a basic material, the experiences of endoscopy in diagnosis and treatment of tumorous conditions in the upper gastrointestinal tract in children. Methods: The objects were 26 patients diagnosed as having tumorous conditions in the upper gastrointestinal tract among 1,283 patients who underwent upper gastrointestinal endoscopic examination at the Department of Pediatrics, Pusan National University Hospital, from January 1994 to July 2004 retrospectively. The characteristics of patients, the chief complaints for endoscopic examination, the sorts of tumors diagnosed, the endoscopic findings of tumors, and the treatment of tumors were analysed. Results: 1) Eleven male and fifteen female were included, whose mean age was $6.93{\pm}4.02years$. 2) The chief complaints for endoscopic examination were abdominal pain (80.7%), vomiting or nausea (30.8%), and gastrointestinal beeding (30.7%) in order. 3) Six cases of ectopic pancreas, five cases of sentinel polyp, three cases of papilloma and vallecular cyst, two cases of Brunner's gland hyperplasia and gastric submucosal tumor, one case of gastrointestinal stromal tumor, duodenal intramural hematoma, T cell lymphoma, lipoma, and Peutz-Jeghers syndrome were diagnosed by endoscopy with or without biopsy. 4) The location of tumors was in the pharynx (19.2%), esophagus (7.7%), gastro-esophageal junction (23.0%), stomach (30.7%) and duodeneum (26.9%). 5) The size of tumors was less than 10 mm in 53.8%, 10~20 mm in 26.9%, more than 20 mm 19.2%. 6) Treatments for tumors included resection by laser, surgical resection, endoscopic polypectomy with a forcep or snare, and observation 7) There was no significant complication. Conclusion: Various and not a few tumors were found in the upper gastrointestinal tract. The endoscopy was accurate, effective, and safe means for diagnosis and treatment of those lesions in children.

Definitely, treatment for gastric cancer is primarily surgical. Detection in early stage of disease and complete surgical resection is the best way to cure gastric cancer. If surgery is planned, careful preoperative evaluation and corrections of physiologic and psychologic abnormalities are essential to reduce perioperative morbidity or mortality. Basic principle of gastrectomy for gastric cancer is an en bloc resection of tumor with adequate margins of normal tissue and with regional lymph nodes and omental tissues. To complete these principles, regional lymph nodes and all omental tissues should be removed altogether during performing various types of gastric resection. The lymph node dissection is one of the most effective procedures for gastric cancer to achieve curative resection. The basic types of gastric resection are distal subtotal gastrectomy and total gastrectomy according to the condition of primary lesions and the status of lymph node metastases. When the primary lesion is located near the esophagogastric junction, it is sometimes hard for a surgeon to select adequate surgical method. Postoperative quality of life in a patient has become a very important factor to be considered in every step of surgical therapy. With increasing incidence of early gastric cancer, a number of surgical trials for limited surgery or endoscopic procedures have been performed, but the long-term clinical results should be carefully analyzed to define the clinical relevance of these new techniques. For patients with disseminated gastric cancer, a palliative procedure can be performed to improve quality of life of patients and to avoid immediate death due to the cancer-related complications.

Purpose: Treatment strategies for early gastric carcinoma (EGC) should be based on achieving a complete cure, but clear indications for limited surgery have not been established. We investigated surgical outcomes for early gastric cancer to determine the optimal? treatment strategy for EGC. Materials and Methods: Subjects included 881 patients who underwent curative surgery for EGC between 1986 and 2003. Retrospective uni & multi-variate analysis for prognostic factors, factors affecting lymph node metastasis, and risk factors for cancer recurrence were analyzed. Results: In multivariate survival analyses, age, operation method, macroscopic appearance and lymph node stage proved to be independent prognostic factors. Lymph node metastasis, depth of tumor invasion, tumor size, lymphatic and venous invasion were also significant risk factors in multivariate analyses. In multivariate analyses for cancer recurrence, depth of tumor invasion and lymph node metastasis proved to be significant risk factors. Conclusion: Appropriate surgical treatment with lymph node dissection is necessary for EGC patients with risk factors for lymph node metastasis.

Lung parenchyma is a common organ for metastases of extrathoracic tumors, but endobronchial metastasis is very rare. In this report, we present a case of endobronchial metastases from renal cell carcinoma (RCC), and this was managed by performing operative resection. A 63-year-old man presented with frequent dry cough; he had previously undergone left nephrectomy and postoperative chemotherapy for grade 2 RCC eight years ago. Computed tomography and bronchoscopy showed an endobronchial tumor from the left lower lobe bronchus to the second carina, and this mass was diagnosed as a necrotic tissue with chronic inflammation at biopsy. During the operation, the mass was revealed to be a metastatic renal cell carcinoma on the frozen section diagnosis and there was no mucosal invasion on the resection margin of the left lower lobe bronchus. We performed lobectomy of the left lower lobe with systemic dissection of the mediastinal lymph nodes. The final histopathologic diagnosis of the endobrochial mass was metastatic RCC and any mediastinal lymph node metastasis was not found. The patient was discharged on postoperative day 10 without any postoperative complications.

Basaloid-squamous cell carcinoma, a biologically high-grade variant of squamous cell carcinoma, is predominantly located at upper aerodigestive tract but it is extremely rare in the esophagus. Recently we experienced a case of basaloid-squamous cell carcinoma of esophagus. A 64 year-old man was referred to our hospital because of mucosal nodularity at 35 cm apart from the incisor in endoscopic examination. Result of Biopsy was squamous cell carcinoma. Left transthoracic esophagectomy was performed. Histologically, the lesion of tumor was basaloid-squamous cell carcinoma and no lymph node metastasis was found.

Diagnosis of early esophageal cancer has become more frequent as a result of improved endoscopic technology, surveillance programmes, and increasing experience and awareness on the part of endoscopists. In early esophageal cancer, squamous cell carcinoma and early adenocarcinoma must be managed differently because they have different origins, pathogenesis. and clinical characteristics. The current treatment options vary widely, from extended resection with lymphadenectomy to endoscopic mucosal resection (EMR) or ablation. None of these treatment options can be recommended universally. Instead, an individualized strategy should be based on the depth of tumor infiltration into the mucosa or submucosa, the presence or absence of lymph node metastases, the multicentricity of tumor growth, the length of the segment of intestinal metaplasia, and comorbidities of the patient. EMR has become increasingly important, both as a diagnostic tool for the staging of esophageal carcinomas and as a method of carrying out definitive treatment when the cancer meets certain criteria in which the risk of lymph-node metastasis is negligible. EMR may be sufficient in a subset of patients who have m1 or m2 squamous cell carcinoma and in patients who have isolated foci of high-grade intraepithelial neoplasia or mucosal cancer.
