Schwannoma or neurilemmoma is an uncommon neoplasm, and it is derived from the peripheral nerve sheath. These tumors most frequently occur in the head, neck and flexor surfaces of the upper and lower extremities, while the porta hepatis and retroperitoneum are rarely implicated. We report here on a case of benign schwannoma in the porta hepatis with compression of the common bile duct, and this was successfully treated by surgical excision. The patient was a 63-year-old woman who had a slow growing upper abdominal mass for 3 years. The abdominal CT scan showed a 12 cm-sized cystic mass with a solid portion, and this was accompanied with intrahepatic bile duct dilatation. Abdominal exploration revealed a yellowish, cystic, encapsulated mass attached to the inferior vena cava, portal vein, the common bile duct and the liver. There has been no evidence of recurrence during 36 months of follow-up.

Situs inversus refers to a mirror image of the viscera, while situs solitus is defined as the normal anatomical situation. Several cases of successful liver transplantation for situs inversus recipients have been reported, and modifications of the standard surgical techniques were used. We report here on a case of cadaveric liver transplantation in an end-stage liver disease patient with situs inversus. The donor liver was rotated clockwise 90 degrees to the left with the right lobe lying in the left upper quadrant and the left lobe pointing down into the left iliac fossa. The donor’s suprahepatic vena cava was oversewn and the infrahepatic vena cava anastomosed end to side to the recipient’s inferior vena cava. The postoperative course was good until the postoperative 26th day, when rupture of a hepatic artery pseudoaneurysm occurred. An emergency laparotomy was done and the hepatic artery was ligated. Despite the hepatic artery ligation, the liver function recovered quite well. But sudden intracranial hemorrhage developed on the postoperative 28th day and sadly, the patient expired on the postoperative 30th day. Complete preoperative evaluation of the recipient is essential for the operative planning, and careful donor selection should be attempted to obtain a smaller graft to allow maximum flexibility for placing the donor liver. The use of a reduced-sized graft should be considered in the case for which a smaller graft is not available. In conclusion, adult situs inversus is no longer a contraindication for a liver transplant, although technical difficulties do exist for this procedure.
전이성 대장암 환자에서 동시성 및 이시성 간전이 종양의 Cyclooxygenase (COX)-1과 Cyclooxygenase (COX)-2 및 E-cadherin 발현의 의의

Purpose: Recent studies have shown that cyclooxygenase (COX)-2 may be involved in colorectal carcinogenesis. In this study, we evaluate the differences of COX-2 expression in patients with synchronous and metachronous hepatic metastasis of colorectal cancer. In addition, the expression of COX-1 and E-cadherin were also evaluated. Methods: Paraffin embedded blocks were obtained from 41 patients who underwent surgery for colorectal cancer with hepatic metastasis. Samples from primary colorectal cancer, synchronous and metachronous hepatic lesions were stained by immunohistochemistry for monoclonal antibody against COX-1, COX-2, and E-cadherin. Results: In colonic COX-1 expression, there was no significant difference in the degree of COX-1 expression between primary colorectal cancer with synchronous hepatic metastasis and that of metachronous hepatic metastasis (P=0.507). In colonic COX-2 and E-cadherin expression, the degree of COX-2 expression was not different between the two groups. But, the patient survival rate in the positive group of COX-1 and COX-2 expression was lower than in the negative group, respectively (P=0.023, P=0.006). Conclusion: The degree of colonic COX-1 and COX-2 expression has an impact on prognosis in synchronous and metachronous hepatic metastasis. Further large-scale study is necessary to determine the meaning of COX-2 expression in colorectal cancer.

Intraductal papillary mucinous neoplasms of the bile ducts (IPMNs-B) are uncommon lesions that are characterized by innumerable papillary fronds that contain fine vascular cores, enriched mucin production and bile duct dilatation. IPMNs-B are histologically similar to intraductal papillary mucinous neoplasms of the pancreas and they are occasionally associated with hepatolithiasis. IPMNs-B are considered to be relatively low- grade malignancy and they merit consideration for aggressive surgery. Thus, early and precise diagnosis is important to maximize patient survival. From July 2002 to March 2006, we identified four patients with IPMNs-B at our hospital. In three patients, intrahepatic or extrahepatic bile duct stones were associated with their condition. Computed tomography and magnetic resonance cholangiography were done in all four cases and this demonstrated marked dilatation of the biliary tree. Endoscopic retrograde cholangiography was done in two cases and a large amount of mucin that was draining from the patulous orifice of the duodenal papilla was seen on endoscopy. However, two cases were initially misdiagnosed as intrahepatic cholangiocarcinoma or choledochal cyst with intrahepatic bile duct stones. All the cases underwent ipsilateral hemihepatectomy with caudate lobectomy. Histologically, one case showed to be adenoma, one case was borderline and two cases were invasive adenocarcinoma.

Biliary cystadenomas are rare cystic neoplasms of the biliary ductal system. Cystadenomas have a tendency to recur, particularly following their incomplete excision, with the potential for malignant transformation. Cystadenocarcinomas are very rare and; despite complete resection, can recur in a short time. A cystadenoma cannot be easily differentiated from a cystadenocarcinoma preoperatively or intraoperatively; therefore, complete surgical resection should be always considered. Four biliary cystadenoma and one biliary cystadenocarcinoma cases, treated at the Kyung Hee Medical Center, between 1998 and 2003, are reported. The patients were comprised of one man and four women, with a mean age of 45 years. Four patients presented with abdominal pain or jaundice, and the other was asymptomatic, with an incidentally discovered liver tumor. Preoperative CT scans demonstrated a multilocular cyst in four patients and a choledochal cyst-like appearance in the other. All patients underwent complete excision. One cystadenoma arose in the extrahepatic bile duct and the other four appeared in the liver. A histological examination revealed a mesenchymal stroma, which resembling ovary, in two cystadenomas. None of the four patients with a cystadenoma developed a recurrence. However, the patient with a cystadenocarcinoma underwent two pulmonary wedge resections for pulmonary metastases 14 and 21 months after the liver resection.
