Summary
This study observed a unique hepatocellular carcinoma (HCC) presentation with simultaneous early-stage development and multicentric growth. Early detection and treatment of small HCCs are crucial for effective surgical resection and preventing metastasis.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Hepatocellular carcinoma (HCC) is a significant global health concern.
- Understanding the early developmental stages of HCC is critical for improving patient outcomes.
- Multicentric development and multistep progression are key aspects of HCC tumorigenesis.
Observation:
- A case of multiple hepatocellular carcinoma (HCC) was resected, exhibiting a 'nodule-in-nodule' appearance.
- Histologic examination revealed a less-differentiated HCC replacing a well-differentiated HCC within the main nodule.
- Two additional early-stage HCCs with preserved portal tracts and preexisting liver structure were identified.
Findings:
- Morphological transition in early-stage HCC development was observed.
- The coexistence of early-stage HCCs suggests multicentric development.
- Preservation of portal tracts in early HCCs is a key diagnostic and prognostic indicator.
Implications:
- Early diagnosis and treatment of HCC, particularly before portal tract invasion, are vital.
- Surgical resection is feasible and effective for small, early-stage HCCs.
- Recognizing multicentric HCC development aids in comprehensive treatment planning and risk assessment.
