RESUMO
Intestinal duplications are rare developmental abnormalities that may occur anywhere in the gastrointestinal tract. The possibility of a malignant change occurring in these duplications is very low. We present a case of adenocarcinoma arising in a duplication of the cecum. A 41-year-old male patient was admitted because of a palpable abdominal mass. Abdominal computed tomography revealed a 6-cm, peripheral wall-enhanced, round, cystic mass in the cecal area. Excision of the mesenteric mass and a right hemicolectomy was performed. Upon histologic examination, the patient was diagnosed with adenocarcinoma arising in a duplication of the cecum.

A 66-year-old woman presented with severe abdominal pain. Abdominal computed tomography revealed a large multicystic mass with a solid component at the tail portion of the pancreas. Distal pancreatectomy was performed with a preoperative diagnosis of mucinous cystic neoplasm. The solid component of the lesion showed both adenomatous and sarcomatous characteristics on histological examination. Immunohistochemical studies showed epithelial cells positive for cytokeratin and an immunoreactive sarcomatous component positive for vimentin. We present here a case of carcinosarcoma of the pancreas with a review of the literature.

Primary natural killer (NK) cell like T cell lymphoma of the terminal ileum is extremely rare. It most frequently occurs in the nasal or paranasal areas and less frequently in the skin, the soft tissue, and the gastrointestinal tract. NK/T cell lymphoma involving gastrointestinal tract has characteristic endoscopic features of Inflammatory bowel disease. We herein describe a first case of primary NK/T cell lymphoma misdiagnosed as Behcet's enteritis of the terminal ileum colonoscopically and complicated by cecal bleeding and perforation.
RESUMO
BACKGROUND/AIMS: Although a few recent studies have reported the effectiveness of endoscopic pancreatic sphincterotomy (EPST), none has compared physicians' skills and complications resulting from the procedure. Thus, we examined the indications, complications, and safety of EPST performed by a single physician at a single center. METHODS: Among 2,313 patients who underwent endoscopic retrograde cholangiopancreatography between January 1996 and March 2008, 46 patients who underwent EPST were included in this retrospective study. We examined the indications, complications, safety, and effectiveness of EPST, as well as the need for a pancreatic drainage procedure and the concomitant application of EPST and endoscopic sphincterotomy (EST). RESULTS: Diagnostic indications for EPST were chronic pancreatitis (26 cases), pancreatic divisum (4 cases), and pancreatic cancer (8 cases). Therapeutic indications for EPST were removal of a pancreaticolith (10 cases), stent insertion for pancreatic duct stenosis (9 cases), nasopancreatic drainage (7 cases), and treatment of sphincter of Oddi dysfunction (1 case). The success rate of EPST was 95.7% (44/46). Acute complications of EPST included five cases (10.9%) of pancreatitis and one of cholangitis (2.2%). EPST with EST did not reduce biliary complications. Endoscopic pancreatic drainage procedures following EPST did not reduce pancreatic complications. CONCLUSIONS: EPST showed a low incidence of complications and a high rate of treatment success; thus, EPST is a relatively safe procedure that can be used to treat pancreatic diseases. Pancreatic drainage procedures and additional EST following EPST did not reduce the incidence of procedure-related complications.

A chronic expanding hematoma (CEH) in the thorax is a rare and specific condition of chronic empyema. CEHs in the thorax are often associated with tuberculosis and/or previous surgical procedures. While the incidental detection of a pleural mass and dyspnea are common clinical manifestations, a few cases present with hemoptysis. We encountered a case of CEH in the thorax. This case is unique in that it developed without a prior history of tuberculosis or surgery and presented with massive hemoptysis accompanied by bronchopleural fistula. We report the third case of CEH in the thorax in Korea with a summary of the clinical characteristics of previous cases.

Acute pancreatitis is a serious disease with fatality rate up to 15%. We recently experienced a case of acute pancreatitis induced by multiple drugs in a patient with ulcerative colitis. A 20-year-old female visited with abdominal pain and hematochezia and diagnosed of ulcerative colitis. Sulfasalazine and prednisolone were used. However, acute pancreatitis occurred after 4 weeks of treatment with additional azathioprine treatment. Drug-induced pancreatitis was suspected, and she was recovered with conventional therapy for acute pancreatitis. Therefore, it was proposed that acute pancreatitis was induced by azathioprine. However, after the administration of sulfasalazine, pancreatitis relapsed. Furthermore, even the re-administration of 5-ASA and azathioprine induced relapse of acute pancreatitis. We concluded that acute pancreatitis was induced by multiple drugs in this patient with ulcerative colitis.
