| Abstract |
We report a case of typical fibrolamellar hepatocellular carcinoma (FL-HCC) in a 16-year-old Japanese boy. This is very rare malignancy in Japan. The patient was referred for investigation of a large hepatic tumor and the results of tests for hepatitis B virus surface antigen and hepatitis C virus antibody were negative. Liver function test results and serum alpha-fetoprotein (AFP) levels were normal; however, the prothrombin induced by vitamin K absence/antagonist II was elevated. Computed tomography (CT) showed a large lobulated heterogeneously enhanced tumor in the posterior section of the liver. We diagnosed FL-HCC and performed posterior sectionectomy of the liver. The resected specimen contained a light brown and green tumor with a central fibrous scar, 10.0 cm in diameter. Microscopic and electron microscopic examinations revealed the typical features of FL-HCC. Immunohistochemically, the tumor cells were positive for cytokeratin (CK) 7, but negative for CK19 and AFP. The patient was alive without recurrence 48 months after surgery. Following this case report, we summarize the clinical features of the Japanese cases documented in the literature. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 January 2015.
All research outputs
#20,249,662
of 22,778,347 outputs
Outputs from Surgery Today
#665
of 990 outputs
Outputs of similar age
#170,599
of 194,468 outputs
Outputs of similar age from Surgery Today
#11
of 21 outputs
Altmetric has tracked 22,778,347 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 990 research outputs from this source. They receive a mean Attention Score of 2.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 194,468 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 21 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
