a Comparison of RNA-seq of the primary lesion (tumor: light blue triangle symbol) and the lymphatic metastatic lesion (lymph: light dark triangle symbol) in our case and in FL-HCC cases (n = 3: yellow circle symbol) and young (< 40 years) patients with HCC (n = 29: green squares) from TCGA database. Principal component analysis of differentially expressed genes in the top 10%; the gene expression of our case is similar to that of previous FL-HCC cases but is a different cluster from that of HCC cases in young patients. b Gene expression analysis of FL-HCC cases (our case and the previous 3 cases) and HCC cases in young patients. The heatmap shows that it clearly distinguished the top 21 and bottom 14 genes
