Abstract:
A 72-year-old man diagnosed with a benign hepatocellular lesion 11 years prior was referred to our hospital for an outgrowth of the tumour in liver segment 7. Extended segmentectomy was performed and the patient's postoperative course was uneventful with no recurrence for 2 years. Histopathological examination confirmed a highly differentiated hepatocellular carcinoma (HCC) coexisting with the hepatocellular adenoma (HCA), and it was suspected to have originated from the HCA. The findings from this case demonstrate that CT can be useful for detecting the transformation of HCA into HCC.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
