The distinction between cholangiocarcinoma (CC) and metastatic colonic adenocarcinoma of the liver (MCA) is often difficult, particularly in needle biopsy and fine-needle aspiration specimens, if histologic features alone are used. To examine the differences in the expressions of the cytokeratin (CK) 7 and 20 in the CCs and MCAs, we performed immunohistochemical studies on surgically resected 19 CCs and 23 MCAs. We used monoclonal antibodies against CK 7 and CK 20, and applied microwave antigen retrieval technique on formalin-fixed, paraffin-embedded tissue. We interpreted diffuse cytoplasmic reactivity found in > or =5% of tumor cells as positive. CCs showed CK 7+/CK 20- immunophenotype in 63%, CK 7+/CK 20+ in 32%, CK 7-/CK 20+ in 5%, and CK 7-/CK 20- in 0%. MCAs exhibited CK 7-/CK 20+ immunophenotype in 87%, CK 7+/CK 20+ in 9%, CK 7-/CK 20- in 4%, and CK 7+/CK 20- in 0%. CK 20-reactive cells in CCs were frequently columnar in shape (p<0.05). In conclusion, the CK 7/CK 20 immunophenotype was useful in the differentiation of CCs from MCAs: the CK 7+/CK 20- immunophenotype strongly suggested CCs, whereas the CK 7-/CK 20+ immunophenotype strongly suggested MCAs.

The results of arthroscopic synovectomy of the knee joints were reviewd in 23 joints of 21 patients hetween May 1992 and June 1996. The results were as follows: 1. Pain, tenderness, swelling, ROM of synovitis syrnpknns were much nsiproved postoperatively. 2. The degrees of articular cartilage damage were closely related to posto-perative functional recovery. 3. Preoperative and postoperative ESR changes were not ditferent signihcantly, 4. Recurrence rate was 17%, 4 cases. Of them, 2 cases were rheumatoid arthritis, 1 case was pigmented villonodular synovitis, I case was nonspecipic synovitis 5. Complicatior of arthrosc:opic synovectomy was nol found. We concluded that arthroscopic synovectoiny was very useful method of early diagnosis and treatment of synovial memhrane diseases.

10.Pedunculated Gallbladder Encircled by Accessory Liver: A case report.

The authors presented a case of gastroschisis with a pedunculated gallbladder embedded in hepatic tissue. The patient was born after fullterm gestation. Due to extensive abdominal wall defect, she succumbed 3 days after birth. There was a pedunculated mass measuring 2.5x1.5x1.5 cm between the liver and distended stomach without any attachment to the liver. The pedicle of the mass was connected to the common bile duct. Cut surface revealed that the mass was an accessory hepatic lobe encircling the gallbladder. The histologic feature of both accessory liver and gallbladder was markedly altered probably due to vascular obstruction. We could find only a single similar case in literlature. That case was associated with Beckwith syndrome and ours was associated with large atrial spetal defect, large patent ductus arteriosus, accessory spleen as well as gastroschisis. The common feature of abdominal wall defect might be a predisposing factor.
