Summary
A rare case showed a single patient with three distinct hepatocellular adenomas (HCAs). This suggests a "benign tumorigenic field effect" may cause different HCA subtypes in one individual.
Area of Science:
- Hepatology
- Oncology
- Gastroenterology
Background:
- Hepatocellular adenomas (HCAs) are benign liver tumors with known subtypes: hepatocyte nuclear factor 1 α-inactivated HCA (H-HCA), inflammatory HCA (I-HCA), and β-catenin activated HCA.
- Inflammatory HCAs constitute the majority (>50%), while H-HCAs represent 35-40%, and β-catenin activated HCAs account for 10%.
Observation:
- A rare case involved a 36-year-old woman with three histologically confirmed steatotic HCAs.
- These three HCAs exhibited distinct phenotypes: I-HCA, β-catenin activated I-HCA, and H-HCA.
Findings:
- This case demonstrates that a single patient can harbor multiple hepatocellular adenomas of different subtypes.
- The presence of diverse HCA phenotypes within one individual supports the hypothesis of a 'benign tumorigenic field effect' contributing to varied genotypes.
Implications:
- The findings highlight the heterogeneity of HCA development, even within a single patient.
- Magnetic resonance (MR) imaging shows high specificity for subtyping HCAs, aiding in diagnosis and management.
- Understanding the field effect may offer new insights into HCA pathogenesis and personalized treatment strategies.
