This paper presents an unusual solid mesenchymal hamartoma of the liver (MHL) in adult. A well defined solid mass in the left lobe of the liver was found in a 57-year-old female. Preoperative radiologic examinations demonstrated solid mass with multifocal calcifications abutting the gallbladder. By light microscopy, the lesion was composed of dense fibrous stroma with hyalinization, bile ducts and thick-walled vessels without hepatocytes. The solid and hyalinized mesenchymal component would suggest an unusual degenerative change representing a burnt-out MHL.

Extragonadal yolk sac tumor (YST) is a relatively rare entity. We describe here the case of an extragonadal YST that occurred in the pancreas with hepatic metastasis in an adult woman. The contrast enhanced CT images of the abdomen revealed a heterogeneous, solitary mass occupying the pancreatic neck and body with slightly inhomogeneous contrast enhancement. Two low-density lesions in the liver were also displayed on the CT images. The patient underwent surgery and the diagnosis of YST was pathologically verified.

Diffuse hepatic hemangiomatosis without extrahepatic lesions is extremely rare in adults. A case of diffuse hepatic hemangiomatosis involving right lobe in a 50-year-old woman was presented. The hemangiomatosis was demonstrated by ultrasonography, computerized tomography (CT) and magnetic resonance image (MRI), and was confirmed histopathologically. Although diffuse hepatic hemangiomatosis is a rare disease in adults, its diagnosis should be considered in patients with diffuse tumor growth in one or both hepatic lobes and distinguished from malignant tumors. The present case is the first documented case of diffuse hepatic hemangiomatosis in an adult in Korea.

Primary adenosquamous carcinoma of the liver is generally considered as an extremely rare subtype of cholangiocarcinoma. It has been reported mostly in a form of case studies. As far as we know, there was only one case report on tumor related with biliary fistula. Recently, we experienced a case of primary adenosquamous carcinoma of liver with a formation of tumor-colonic fistula. A 54-year-old man was transferred to our hospital due to liver mass detected by abdominal ultrasonogram. Dynamic computed tomogram of liver showed a large irregular hypodense mass without rim enhancement in right lobe of liver and also suggested a fistula formation between the tumor and hepatic flexure of right colon. Colonoscopic examination showed a large colonic wall defect in hepatic flexure and a friable, nodular mucosa around the defected colonic wall. Extended right lobectomy and right hemicolectomy were done. Microscopically, the tumor was composed of squamous cell carcinoma mainly with foci of the adenocarcinoma component.

OBJECTIVETo evaluate the clinical efficacy of percutaneous targeted argon-helium cryoablation for soft tissue sarcoma and analyze the changes in CT findings and side effects in relation to the treatment.

METHODSThirty-two patients with soft tissue sarcoma were treated with CT-guided argon-helium cryoablation.

RESULTSThree months after the treatment, 52 tumors showed obvious reduction in size with a total complete and partial remission rate of 73.1%. Postoperative CT scanning displayed low-density local necrosis in the tumors after cryotherapy, and consolidation of the lesions was observed at 3 months and lesion disappearance at 1 year after the therapy. The complications included pneumothorax, coughing, hemoptysis, fever, and slight elevation of aminotransferase.

CONCLUSIONCT-guided percutaneous targeted argon-helium cryoablation is safe and effective for lung cancer with minimal invasions.

BACKGROUND/AIMS: The follow-up strategy after hepatectomy for hepatocellular carcinoma (HCC) usually depends on the experience of physician, resulting in frequent imaging studies, which leads to increased cost. Hence, we investigated the role of monitoring alpha-fetoprotein (AFP) levels after hepatectomy in patients with preoperative high AFP. METHODS: From January 2000 to December 2004, 66 patients who underwent curative hepatectomy due to HCC with preoperative AFP level >400 ng/mL were reviewed. Changes in AFP level after the operation were investigated. The recurrence was suspected in case of two consecutive increase of AFP over cut-off value. Cut-off value was determined by ROC curve. All patients were divided into 2 groups: patients who met the definition (Group S) and those who didn't (Group D). RESULTS: AFP level of 20 ng/ml was proposed as the cut-off value for diagnosis of recurrence by ROC curve. Thirty two patients who didn't have the AFP level decreased below 20 ng/ml after the resection had HCC recurred, whereas 16 out of 34 patients who had AFP decreased had tumor recurrence. The AFP level of patients without recurrence was kept below 20 ng/ml during the follow-up. The AFP level of 44 out of 48 recurred patients increased over 20 ng/ml upon recurrence. By definition, group D were 5 patients. In 4 patients of group D, the AFP level didn't increase above 20 ng/ml upon recurrence. These patients had HCC and they recurred 1 year after the surgery. CONCLUSIONS: In patients with preoperative AFP level >400 ng/ml, the AFP level tended to increase above 20 ng/ml at recurrence mostly within 1 year. Hence, we proposed that these patients could be monitored by only AFP until 1 year after surgery.
