Clinical Report: Autopsy Findings in a Rare Case of Rapidly Progressive Adult-onset Diffuse Hepatic Hemangiomatosis
Background
Diffuse hepatic hemangiomatosis (DHH) is an uncommon benign vascular tumor of the liver, primarily affecting adults. Its clinical presentation can mimic more aggressive conditions such as hepatic angiosarcoma, complicating diagnosis and management.
Data Highlights
No numerical data or trial data available in the source material.
Key Findings
DHH is characterized by an infiltrative growth pattern and dilated vascular spaces without marked atypia.
The case presented involved a 51-year-old female with multiple hepatic lesions initially suspected to be hemangiomas.
Rapid progression of lesions was observed over six months, raising concerns for hepatic angiosarcoma.
Autopsy revealed multiloculated cystic vascular spaces lined with pleomorphic endothelial cells, supporting the diagnosis of DHH.
No histological heterogeneity or extrahepatic lesions were found during autopsy.
Pleomorphic endothelial cells may be related to treatment artifacts from prior chemotherapy.
Clinical Implications
Clinicians should be aware of the diagnostic challenges posed by DHH, particularly in differentiating it from hepatic angiosarcoma. Careful histopathological evaluation is essential for accurate diagnosis, especially in cases of rapid clinical progression.
Conclusion
This case underscores the importance of recognizing the clinical and pathological features of DHH to avoid misdiagnosis and ensure appropriate management.
