Teratoma is one of germ cell tumor, common neoplasm in women of reproductive age, but it can arise at any age. Its malignant transformation is rare, less than 2%, frequently at older age. Nearly all the cases are squamous, sarcomatous and adenomatous transformation. Here we present a case of mixed transformation, adeno-squamous cell carcinoma with brief review of the concerned literature.

Intramural hematoma(IMH) and penetrating aortic ulcer have been increasingly recognized as causes of acute aortic pathology in addition to aortic dissection. The presence of the intimal tear and a flap traversing the aortic lumen is considered to be a most reliable differential point of aortic dissection and IMH. Transesophageal echocardiography(TEE) has become a valuable modality for the diagnosis, prognosis and management of acute aortic syndrome with the unique advantages of portability and the ability to obtain high-resolution real time images. Endovascular Stent-graft placement over the primary entry tear may be an alternative to open surgery because it can close the intimal tear, which leads to thrombosis of the false lumen, excluding flow through the intimal tear and redirecting aortic flow exclusively into the true lumen. We report 88 year-old male with aortic dissection in descending thoracic aorta, successfully treated with endovascular Stent-graft implantation, which was mimicking intramural hematoma by its appearance and subclinical intimal tear diagnosed exclusively by TEE against other imaging studies.

PURPOSE: A sensitive assay to detect minimal residual disease in neuroblastoma is necessary for accurate assessment of disease status and optimal treatment. In this study, we compared the usefulness of sensitive methods, flow cytometry and RT-PCR for the detection of minimal residual disease in neuroblastoma. METHODS: Eighteen patients who were newly diagnosed and treated at Severance Hospital since 1999 were included in this study. Samples from bone marrow, peripheral blood, and peripheral blood stem cell product were examined for tumor cell contamination by RT-PCR (TH RT-PCR) to detect tyrosine hydroxylase mRNA and by flow cytometry identifying CD9+/CD56+/CD45- cells. RESULTS: We analyzed 20 cases from 18 patients, which were assayed by both methods at the same time. Among 20 cases, 16 cases showed same results, which were compatible with histologic results and clinical course, and 4 cases showed different results. One case of them showed positive result in histology and flow cytometry, but negative result in TH RT-PCR. The other 3 cases showed negative results in flow cytometry, but positive results in TH RT-PCR, and 1 patient of them relapsed. Among 16 patients, 2 patients, showing positive results in only TH RT-PCR, relapsed. CONCLUSION: Detection of minimal residual disease using TH RT-PCR and flow cytometry was effective and useful in evaluating disease status and deciding for proper treatment.

Cord blood is a useful source of allogeneic hematopoietic stem cells for bone marrow reconstitution. The number of umbilical cord blood transplants is increasing worldwide. In this a case 15- month-old boy with acute myeloid leukemia was treated with umbilical cord blood transplant from an HLA-3 loci mismatched unrelated donor. Granulocyte recovery greater than 500/mm3 occurred at day 49, and the platelet recovered greater than 20,000/mm3 independent of transfusion at day 81 after stem cell infusion.

PURPOSE: In 1970, the Berlin-Frankfurt-Munster(BFM) group introduced an intensification therapy after remission induction to reduce relapse of acute lymphoblastic leukemia(ALL) in childhood. Delayed intensification(DI) phase has been included for treatment of ALL in our hospital since the mid-1990s. The purpose of this study is to evaluate the outcome with vs. without DI phase and the outcome with two vs. one DI phase for intermediate risk patients. METHODS: One hundred and thirty nine children with ALL who were treated at the Department of Pediatrics of Wonju Christian Hospital and Yonsei University Medical Center between March, 1990 and July, 2002 were analysed retrospectively. RESULTS: Thirty-eight patients were treated with a DI phase, and 101 patients were treated without a DI phase. Among the DI patients, seven patients were treated with a double DI phase. Five-year overall survival(OS) in the low, intermediate, and high risk groups were 68%, 66% and 58%, respectively. 5-year OS in DDI, DI, and control were 95%, 86% and 40%, espectively. In the low risk group, 5-year event free survival(EFS) in DI, and control were 94% and 58%, respectively. CONCLUSIONS: Delayed intensification improved EFS on childhood ALL in all risk groups.

The endoscopic retrograde cholangiopancreatography (ERCP) has become a commonly performed endoscopic procedure in biliary pathology. ERCP is a relatively safe procedure. however, there are chance of potentially severe complications; pancreatitis, hemorrhage, infection, and perforation. Duodenal perforation, uncommon but severe complication of ERCP, occurred in less than 1% of most series. According to the related mechanism, anatomical location, and the severity of injury, three to four distinct types of perforations have been described. We experienced the barotrauma associated duodenal perforation during endoscopic hemostasis in patient with EST site bleeding. This duodenal perforation was related with excessive air inflation to maintain the patency of a lumen. Endoscopists performing ERCP should bear in mind that continued air inflation may lead to duodenal perforation.

Ileal Dieulafoy lesion is an unusual vascular abnormality that can cause gastrointestinal bleeding. It can be associated with massive, life-threatening hemorrhage and requires urgent angiographic intervention or surgery. Ileal Dieulafoy lesion is hard to recognize due to inaccessibility and normal-appearing mucosa. With advances in endoscopy, aggressive diagnostic and therapeutic approaches including enteroscopy have recently been performed for small bowel bleeding. We report two cases of massive ileal Dieulafoy lesion bleeding diagnosed and treated successfully by single balloon enteroscopy with a review of the literature.

A peritonsillar abscess is one of the most commonly occurring deep space infections of the head and neck in adults and children. A peritonsillar abscess that appears in newborns, however, is extremely rare. The treatment of a peritonsillar abscess requires both the selection of appropriate antibiotics and the best procedure to remove the abscessed material. We report a case of a peritonsillar abscess in a 40-day-old infant who was treated with antibiotic therapy alone.
