RESUMEN

Most cases of gastric subepithelial lesions follow a good clinical course; however, some lesions progress to malignant tumors, and treatment of tumors with a high risk of malignancy is essential. Surgical excision has been the primary treatment for tumors originating from the propria muscle layer, but it has the disadvantages of being invasive and causing postoperative functional abnormalities. With the development of endoscopic techniques and instruments, the role of endoscopic resection, which is a less invasive method for the removal of gastric subepithelial lesions, has been attracting attention. We performed an endoscopic full-thickness resection for 8 patients with gastric subepithelial lesions originating from the muscularis propria. No fatal complications occurred. Our findings suggest the need to develop various devices for resection and closure and to accumulate further experience through additional studies to prevent complications and specimen loss.

RESUMEN

Signet ring cell carcinoma is a rare form of gallbladder cancer and has a worse prognosis. Since few cases have been reported, information regarding the behavior and prognosis of the gallbladder carcinoma is limited. About twenty four cases of gallbladder signet ring cell carcinoma have been reported so far. We present a rare case of primary signet ring cell carcinoma of the gallbladder. A 58-year-old male presented with epigastric pain. Abdominal computed tomography showed diffuse gallbladder wall thickening with enhancement, gallstones, and choledocholithiasis. After endoscopic treatment of choledocholithiasis, laparoscopic cholecystectomy was performed. Pathologic examination of the resected gallbladder revealed adenocarcinoma of signet ring cell type in the epithelium. Immunohistochemical stain for cytokeratin 7 was positive for tumor cells. The final pathologic diagnosis was primary signet ring cell carcinoma of the gallbladder. Lymph node metastasis was detected and he received chemotherapy and radiotherapy. After one year of follow-up, bone metastasis in the lumbar spine and malignant ascites were found. The patient is being provided with palliative care.

RESUMEN

Perforation of the biliary tree mostly results from injury to the bile duct during surgery or procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and spontaneous bile duct perforation is rare in adults. As the clinical picture varies, early diagnosis and treatment of spontaneous biliary peritonitis is difficult. A 52-year-old male patient presented with abdominal pain and intractable ascites. He already experienced severe abdominal pain 2 months ago and underwent percutaneous pigtail drainage for the ascites at nearby hospital. ERCP showed large filling defect with leakage of contrast media from the mid common bile duct (CBD) into the peritoneal cavity. We performed endoscopic sphincterotomy and extracted CBD stones with basket and balloon catheter. Then fully covered self expandable metal stent was placed in CBD. After the procedure, the symptom was improved and the amount of pigtail drainage from abdominal cavity was dramatically decreased. 6 weeks later, removing the metal stent, there was no more leakage of contrast media into peritoneal cavity. We report a very rare case of spontaneous bile leakage which was successfully managed with placement of metal stent.

RESUMEN

Malignant rhabdoid tumor was first discovered in the kidney, and rhabdoid tumor of the lung was first reported in 1995. These were included as the variants of large-cell carcinoma, according to the 1999 World Health Organization classification of lung tumors. The rhabdoid tumor of the lung exhibits aggressive biological behavior and has a poor prognosis, and only a few reports of this tumor exist. We report a case of lung carcinoma with a rhabdoid phenotype, initially misdiagnosed as an aspergilloma, in a 48-year-old man who presented with recurrent hemoptysis. The chest computed tomography scans showed a huge consolidative lesion with an air crescent sign in the left upper lung and no contrast-enhancing lesion. An aspergilloma was diagnosed by the radiologist. However, after surgical excision and pathological examination, rhabdoid carcinoma was diagnosed. A surgical resection helps to make it possible to pathologically distinguish a malignancy from an aspergilloma.
