A case of type 1 infantile hemangioendothelioma of the liver in a 3 month old male infant who had an abdominal mass incidentally noted at 40 days of age, is described. Grossly, the tumor showed a well circumscribed, pinkish gray and gelatinous mass with areas of central necrosis, multifocal thrombi and hemorrhages, and small cysts. Microscopically, the lesion consisted of numerous vascular channels of various size lined by a single layer of flat or plump endothelial cells. Areas of infarction, thrombosis and calcification, and formation of cavernous hemangiomatous foci were also noted in the lesion. Ultrastructurally, the cells had the characteristics of endothelium, including basal lamina, pinocytic vesicles, and Weibel-Palade bodies. Factor VIII-associated antigen was demonstrated in the tumor cells.

OBJECTIVETo evaluate the risk factors for recurrence in patients with hepatocellular carcinoma (HCC) after liver transplantation (LT).

METHODSOne hundred and fifteen small HCC patients, who met Milan criteria (single<5 cm or showing up to three nodules, each of them<3 cm without major vascular invasion or distant metastasis) and underwent LT in our hospital from January 2007 to November 2013, were enrolled in the study. The risk factors for recurrence were analyzed by Cox regression and the influence of the Milan criteria and microvascular invasion (MVI) on the disease-free survival (DFS) and recurrence of patients were assessed with survival analysis and ROC method.

RESULTSNinety-eight out of 115 small HCC patients were included for analysis, the 1-,3-, 5-year overall survival of patients was 91.8%, 80.6%, 79.6% and DFS was 87.8%, 74.5%, 73.5%, respectively. Survival analysis identified that MVI, macro-vascular invasion, exceeding the Milan criteria and pre-transplant down-staging treatment were related to tumor recurrence (P<0.05). Multivariate Cox regression analysis showed that MVI and exceeding the Milan criteria were two independent prognostic indicators for early recurrence of small HCC after LT. The 1-,3-,5-year DFS for 69 patients without MVI and 29 patients with MVI were 92.8%, 85.5%, 85.5% and 75.9%, 55.2%, 48.3%, respectively (P<0.01). The 1-,3-,5-year DFS for 84 patients meeting the Milan criteria and 14 exceeding the Milan criteria were 91.7%, 83.3%, 79.8% and 64.3%, 42.9%, 42.9%, respectively (P<0.01).

CONCLUSIONFor early HCC patients undergoing LT, the presence of MVI would predict tumor recurrence and can be an indicator for the adjuvant treatment or other salvage treatments.

OBJECTIVETo investigate the pathological feature of primary hepatic carcinoma and the clinical significance.

METHODSFrom August 2000 to December 2007, there were 89 patients with cirrhosis and carcinoma of liver who accepted whole liver resection. The whole liver was cut into 10 mm slices to examine the tumor size, number, distribution, capsule, satellite nodes, portal vein tumor thrombi (PVTT). The invaded adjacent tissue and lymph nodes were recorded, the distance from satellite to major tumor was measured, then histological examinations were carried out, and the final diagnosis was made by pathologists.

RESULTSThe total of 89 cases included hepatocellular carcinoma in 86 cases and cholangiocarcinoma in 3 cases; 53 cases with multiple tumors and 36 cases with solitary tumor; complete capsule only in 14 cases, no obvious margin in 11 cases, 13 cases had a major tumor in the right lobe and a small tumor in the left lobe; 8 of 25 cases with gross invaded tissue were confirmed by histological examination, 7 of 16 cases with swollen lymph nodes were infiltrated by cancer cells. There were 47 cases with PVTT (47.2%) and 39 cases with satellite nodes (43.8%). PVTT and satellite nodes increased with the increase of sizes and the numbers of the tumors. The distance from satellite node to major tumor mostly were 0.5 - 3.0 cm.

CONCLUSIONSThe whole explanted liver can completely reflect the characteristics of growth and infiltration of hepatic carcinoma. Attention must be paid to the small cancer lesions in another lobe, distal satellite nodes from major tumor, and tumor thrombi in a small branch of portal vein, which can not be found by imaging, and might influence the curative effectiveness after liver resection or transplantation.

Hepatic fibrosis and cirrhosis are the consequences of many types of chronic liver disease. The precise quantification of fibrosis is important to predict the prognosis and monitor the response of treatment modality. The liver biopsy has a role to estimate the stage of fibrosis. However, its sensitivity is below 80%. Its use is limited by sampling errors, inter- and intraobserver variability and possible morbidity and mortality. There is increasing attention to developing clinical algorithms and new noninvasive alternative techniques to predict the stage of fibrosis. However none of these can replace the utility of liver biopsy in the intermediate stage of hepatic fibrosis. Therefore, the liver biopsy is still the "gold standard" to assess the precise stage of hepatic fibrosis.
