Summary
This report details a rare case of hepatic angiomyolipoma (AML), a liver tumor. Diagnosis involved imaging and confirmed by surgery, highlighting AML
Area of Science:
- Hepatobiliary Medicine
- Surgical Pathology
- Diagnostic Imaging
Background:
- Hepatic angiomyolipoma (AML) is a rare benign liver tumor.
- Accurate diagnosis is crucial for appropriate management.
Observation:
- A 66-year-old female presented with an inhomogeneous liver lesion.
- Ultrasonography, CT, MRI, and DSA revealed a hypervascular mass in the left hepatic artery territory.
Findings:
- Microscopic examination confirmed the tumor composed of fat, vascular, and smooth muscle cells.
- Immunohistochemistry showed spindle cell reactivity to HMB-45, alpha-smooth muscle actin, and Melan-A/MART-1.
- These findings were consistent with hepatic angiomyolipoma.
Implications:
- This case underscores the importance of comprehensive imaging in diagnosing rare liver tumors.
- Surgical resection was successfully performed.
- Understanding the immunophenotype aids in definitive diagnosis of hepatic AML.
