Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is characterized by a severe idiosyncratic reaction including rash and fever, often with associated hepatitis, arthralgias, lymph node enlargement, or hematologic abnormalities. The mortality rate is approximately 10%, primarily owing to liver failure with massive or multiple disseminated focal necrosis. Here, we report a case of a 14-year-old girl treated with vancomycin because of a wound infection by methicillin-resistant Staphylococcus aureus, who presented with non-specific symptoms, which progressed to acute liver failure, displaying the hallmarks of DRESS syndrome. With the presence of aggravated hepatic encephalopathy and azotemia, the patient was refractory to medical treatments, she received a living-donor liver transplantation, and a cure was achieved without any sign of recurrence. Vancomycin can be a cause of DRESS syndrome. A high index of suspicion and rapid diagnosis are necessary not to miss this potentially lethal disease.

Background: Radiofrequency ablation (RFA) is the most widely used and studied method internationally for the local treatment of liver tumors. However, the extension of coagulation necrosis in one RFA procedure is limited and incomplete coverage of the damaged area can lead to a high local recurrence rate. Objective: In this study, we compared the effects of different solutions in enhancing hepatic radiofrequency by establishing a rabbit VX2 liver cancer model. We also determined the optimal solution to maximise effects on the extent of RFA-induced coagulation necrosis. Methods: Thirty VX2 tumor rabbits were randomly assigned to five groups: group A, RFA alone; group B, RFA with anhydrous ethanol injection; group C, RFA with 5% hypertonic saline injection; group D, RFA with lidocaine injection; and group E, RFA with a mixed solution. Routine ultrasound examinations and contrast-enhanced ultrasound (CEUS) of the ablation areas were performed after RFA. Then, we measured the major axis and transverse diameter and compared the areas of coagulation necrosis induced by RFA. Results: The mean ablation area range increased in groups B, C and especially E, and the scopes were greater compared with group A. Preoperative application of anhydrous ethanol, hypertonic saline, lidocaine and the mixed solution (groups B, C, D and E, respectively) resulted in larger coagulation necrosis areas than in group A (p<0.05). Among the groups, the coagulation necrosis areas in group E was largest, and the difference was statistically significant compared with other groups (p<0.05). Pathological findings were consistent with imaging results. Conclusions: A mixture of dehydrated alcohol, hypertonic saline and lidocaine injected with RFA increases the extent of coagulation necrosis in the liver with a single application, and the mixed solution is more effective than any other injection alone.

From January 1984 to December 1991, One hundred sixty five patients with carcinomoa of the esophagus were treated surgically at the department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital. Among them, hospital records were available in 121 patients and were included in this study. There were 115 men and 6 women, with ages ranging from 40 years to 79 years[mean age of 59.2 years]. The most frequent preoperative symptoms included dysphagia[72.7%], weight loss[60.3%], chest pain or discomfort[14.9%], general malaise[13.2%]. All were treated surgically: 100 patients were managed by curative or palliative resection with reconstruction, and 6 by palliative bypass surgery. In 15 patients, explorative thoracotomy or laparotomy was only done due to unresectability. [operability: 87.6%, resectability: 82.6%] All specimens[those from resectable 100 cases] were sent to pathology, and histopathologic examinations were done; squamous cell carcinomas were found in 95 cases, adenocarcinoma in l. Adenosquamous carcinomas were found in 3, and malignant melanoma in l. Postoperative complications occurred in 34 cases; anastomotic site leakage[10], which was followed by empyema in 9 of them, wound problem[7], hepatic failure[6], pneumonia [3], post-operative bleeding[3], chylothorax[2], post-operative stricture[2], sepsis[1], and tracheobronchial fistula[1]. Hospital deaths were in 6 cases[Hospital mortality: 5.0%]. During the follow up period, 26 patients were proven to be recurrence of cancer locally or distantly. The one, two, and five-year actuarial survival raf.es were 71.3$\pm$4.5%, 57.4$\pm$5.6%, 34.7$\pm$8.9%, respectively. The data from this study suggested that esophagectomy with reconstruction of gastrointestinal tract could be performed with a low operative mortality and a few serious postoperative complications and achieved reasonable long term palliation for carcinoma of the esophagus.

Primary neuroendocrine tumors originating from the extrahepatic bile duct are rare. Among these tumors, large cell neuroendocrine carcinomas (NECs) are extremely rare. A 59-year-old man was admitted to Sanggye Paik Hospital with jaundice that started 10 days previously. He had a history of laparoscopic cholecystectomy, which he had undergone 12 years previously due to chronic calculous cholecystitis. Laboratory data showed abnormally elevated levels of total bilirubin 15.3 mg/dL (normal 0.2-1.2 mg/dL), AST 200 IU (normal 0-40 IU), ALT 390 IU (normal 0-40 IU), and gamma-glutamyl transferase 1,288 U/L (normal 0-60 U/L). Serum CEA was normal, but CA 19-9 was elevated 5,863 U/mL (normal 0-37 U/mL). Abdominal CT revealed a 4.5 cm sized mass involving the common bile duct and liver hilum and dilatation of both intrahepatic ducts. Percutaneous transhepatic drainage in the left hepatic duct was performed for preoperative biliary drainage. The patient underwent radical common bile duct and Roux-en-Y hepaticojejunostomy for histopathological diagnosis and surgical excision. On histopathological examination, the tumor exhibited large cell NEC (mitotic index >20/10 high-power field, Ki-67 index >20%, CD56 [+], synaptophysin [+], chromogranin [+]). Adjuvant concurrent chemotherapy and radiotherapy were started because the tumor had invaded the proximal resection margin. No recurrence was detected at 10 months by follow-up CT.

Objective : Hydatid cyst disease is caused by the parasite Echinococcus granulosus. It is rarely seen in the vertebral system, occurring at a rate of 0.2-1%. The aim of this study is to present 12 spinal hydatid cyst cases, and propose a new type of drainage of the cyst. Methods : Twelve cases of spinal hydatid cysts, surgical operations, multiple operations, chronic recurrences, and spinal hydatic cyst excision methods are discussed in the context of the literature. Patients are operated between 2005 and 2016. All the patients are kept under routine follow up. Patient demographic data and clinicopathologic characteristics are examined. Results : Six male and six female patients with a median age of 38.6 at the time of surgery were included in the study. Spinal cyst hydatid infection sites were one odontoid, one cervical, five thoracic, two lumbar, and three sacral. In all cases, surgery was performed, with the aim of total excision of the cyst, decompression of the spinal cord, and if necessary, stabilization of the spinal column. Mean follow up was 61.3 months (10-156). All the patients were prescribed Albendazole. Three patients had secondary hydatid cyst infection (one lung and two hepatic). Conclusion : The two-way drainage catheter placed inside a cyst provides post-operative chlorhexidine washing inside the cavity. Although a spinal hydatid cyst is a benign pathology and seen rarely, it is extremely difficult to achieve a real cure for patients with this disease. Treatment modalities should be aggressive and include total excision of cyst without rupture, decompression of spinal cord, flushing of the area with scolicidal drugs, and ensuring spinal stabilization. After the operation the patients should be kept under routine follow up. Radiological and clinical examinations are useful in spotting a recurrence.

Purpose: The aim of this study was to analyze the clinical and the histopathological characteristics of mucosa associated lymphoid tissue (MALT) lymphomas in the stomach. Materials and Methods: We retrospectively reviewed the medical records of 22 patients who had been treated at Samsung Medical Center from Jan. 1995 to Sep. 2000 and who had been pathologically proven to have a MALT lymphoma. The factors we analyzed were operative procedure, tumor stage, and histopathological characteristics. Results: Of 3658 patients with a gastric malignancy, 22 patients proved to have a MALT lymphoma ($0.6\%$). There were 7 men and 15 women whose ages ranged from 25 years to 70 years (mean, 48.8 years). Forteen cases were located in the antrum, 4 ($18\%$) in the body and 4 ($18\%$) in the fundus or the high body. Nineteen of these patients were managed with total gastrectomy and splenectomy and 3 with radical subtotal gastrectomy. Histopathologically the tumor was limited to the mucosa in 3 patients ($1.36\%$), to the submucosa in 13 ($59.1\%$) and extended to the muscularis propria in 6 ($27.3\%$). Lymph node involvement was seen in 12 patients ($54.6\%$). There was no splenic or hepatic involvement. Bone marrow involvement was not seen in any patients. H. pylori was identified in 11 patients (50$\%$). During the mean follow-up period of 32.7 months, there were no reports of tumor recurrence or death. Conclusion: MALT lymphomas rarely disseminate by the time of diagnosis and rarely involve the bone marrow. Lymph node involvement is relatively high and a total gastrectomy is effective in managing patients with a MALT lymphoma.
