OBJECTIVETo analyze the clinicopathologic characteristics of well-differentiated hepatocellular carcinoma (WD-HCC), and to find clues for its pathologic diagnosis and differential diagnosis.
METHODSSeventy-three cases of WD-HCC were studied with clinical data analysis, gross and microscopic examination.
RESULTSAmong the 73 cases, the prevalence of HBV (+) and/or HCV (+) was 94.5% (69/73), liver cirrhosis was 80.8% (59/73), increased hepatic cell density was 95.9% (70/73), dilated and irregular hepatic sinus was 89.0% (65/73), prominent trabecularism was 89.0% (65/73), increased cytoplasmic eosinophilia or basophilia was 90.4% (66/73), glandular-like structure was 16.4% (12/73, and fatty degeneration was 42.4% (31/73) .
CONCLUSIONSThere are important clinicopathologic features associated with WD-HCC. These features are useful in the differential diagnosis of WD-HCC with dysplastic nodule (DN), focal nodular hyperplasia (FNH) and hepatocellular adenoma.

A 7-year-old female Eurasian otter (Lutra lutra) at the Seoul Grand Park, Korea, died after displaying depression, anorexia, weight loss and rough skin for several days. At necropsy, a solitary friable round mass, which was approximately 12 x 9 x 5 cm and mottled dark red and yellow, was found bulging from the right hepatic lobe. Microscopically, the nonencapsulated, poorly circumscribed mass was composed of solid sheets of neoplastic hepatocytes. In addition, numerous small tan foci, ranging from 0.5 to 1.0 cm in diameter, were evenly scattered throughout the pancreatic tissue. These foci were found to be nonencapsulated, well-demarcated hyperplastic nodules of the exocrine pancreatic gland. We observed neither intrahepatic nor extrahepatic metastases. Based on the gross and microscopic changes, we diagnosed the animal as having a hepatocellular adenoma accompanied by exocrine pancreatic nodular hyperplasia.

Multiple hepatic adenoma is a rare entity in which characterized by the presence of numerous adenomas within an otherwise normal liver. Although the disease is rare, its important lies in its tendency to produce symptoms such as abdominal pain and its potential for abdominal hemorrhages. However, the prognosis and the evolution of this entity is generally uncertain. We report a case multiple hepatic adenomas, which was proved by pathology, in 24 years old man who has been prescribed long-term oral steroid due to rheumatoid arthritis. He underwent incisional biopsy and mass enucleation of hepatic tumors with 95% alcohol injection. In the case, dissection of the liver showed many other diffuse and smaller nodules. Histologically, tumor was liver cell adenoma without pleomorphism, or mitosis. During the follow-up period of two years, new nodules were found by ultrasonography and magnetic resonance image without developed of serious complications.

OBJECTIVETo study the expression and significance of GPC3, CD10 and CD34 in hepatocellular carcinoma (HCC), dysplastic nodules (DN), cirrhotic regenerative nodules (CRN), focal nodular hyperplasia (FNH) and hepatocellular adenoma (HA).
METHODSImmunohistochemical study for GPC3, CD10, CD34 and AFP was performed on 80 cases of HCC (30 cases of well-differentiated HCC and 50 cases of advanced HCC), 30 cases of DN (18 cases of high-grade DN and 12 cases of low-grade DN), 36 cases of CRN, 20 cases of FNH and 20 cases of HA.
RESULTS(1) The positive expression rate of GPC3 was 92% (46/50) in advanced HCC, 66.7% (20/30) in well-differentiated HCC, 2/18 in high-grade DN, and 0 in low-grade DN, CRN, FNH and HA. The expression rate of GPC3 in well-differentiated HCC was lower than that in advanced HCC and higher than that in high-grade DN (P < 0.05). (2) The negative expression rate of CD10 was 78% (39/50) in advanced HCC, 43.3% (13/30) in well-differentiated HCC, 20% (4/20 and 4/20) in both FNH and HA, 2.8% (1/36) in CRN and 0 in both high-grade DN and low-grade DN. The occurrence of CD10-strongly positive cells was 2% (1/50) in advanced HCC, 16.7% (5/30) in well-differentiated HCC, 15/18 in high-grade DN, 11/12 in low-grade DN, 80.6% (29/36) in CRN and 60% (12/20 and 12/20) in both FNH and HA. The positive expression rate of CD10 in well-differentiated HCC was higher than that in advanced HCC and lower than that in high-grade DN, low-grade DN, CRN, FNH and HA (P < 0.05). (3) The positive expression rates of CD34 in advanced HCC and well-differentiated HCC ranged from 25% to 100% [and strongly positive in 76% (38/50) and 70% (21/30), respectively]. The rates in high-grade DN and low-grade DN ranged from 5% to 25% (and weakly positive in 16/18 and 10/12, respectively). In CRN, the rate ranged from 0 to 5% [and weakly positive in 27.8% (10/36)]. In FNH and HA, the positive rates ranged from 25% to 50%. The positive expression rate of CD34 in well-differentiated HCC was significantly higher than that in high-grade DN, low-grade DN, CRN, FNH and HA (P < 0.05). (4) The positive expression rate of AFP was 44% (22/50) in advanced HCC, 20% (6/30) in well-differentiated HCC, no expression in DN, LCN, LCN, FNH and HA. The positive expression rate of AFP in well-differentiated HCC was lower than that in advanced HCC and higher than that in LCN, FNH and HA. The different expression had statistical significance (P < 0.05).
CONCLUSIONSGPC3 is a relatively sensitive and specific marker in pathologic diagnosis of HCC. When coupled with immunohistochemical results of CD34, CD10 and AFP, GPC3 is useful in differentiating HCC from DN, LCN, FNH and HA.

Hepatocellular adenoma (HA) is a benign hepatic lesion that predominantly occurs in young women. Most hepatocellular carcinomas (HCC) arise in a cirrhotic liver during the fifth or sixth decades. There have been several reported cases of HCC developing from HA in female patients. However, there are rare cases about HCC arising in HA in a non-cirrhotic male patient. We have recently encountered a 53-year-old man who had a liver mass in a non-cirrhotic liver, and the liver mass was compatible with HA on the pre-operative computed tomography. The mass was completely resected and the histopathology revealed a focus of HCC arising in HA. We report here on this case along with a brief review of the relevant literature

Focal nodular hyperplasia (FNH) is the second most common benign hepatic tumor that is usually found in women. Diagnosis of FNH mainly depends on imaging studies such as color Doppler flow imaging, computed tomography, and magnetic resonance imaging. It is characterized by the presence of stellate central scar and is nowadays incidentally diagnosed with increasing frequency due to advances in radiologic imaging technique. FNH typically presents as a single lesion in 70% of cases and generally does not progress to malignancy or recur after resection. Herein, we report a case of a young male patient with recurrent multiple FNH who underwent surgical resection for presumed hepatic adenoma on computed tomography.
