Summary
This report details a rare case of primary liver malignant mesothelioma in a patient without asbestos exposure. The study highlights diagnostic markers and treatment challenges for this uncommon hepatic tumor.
Area of Science:
- Hepatobiliary Surgery
- Oncology
- Pathology
Background:
- Primary malignant mesothelioma of the liver is an exceptionally rare neoplasm.
- This case involves a 53-year-old male presenting with an incidentally discovered liver mass.
Observation:
- Imaging revealed a liver dome tumor primarily supplied by the inferior phrenic artery.
- Surgical resection included part of the diaphragm.
Findings:
- Microscopic examination showed epithelioid cells with eosinophilic cytoplasm and prominent nucleoli.
- Immunohistochemistry confirmed epithelioid mesothelioma, positive for calretinin and cytokeratin 5, and negative for hepatocyte markers.
Implications:
- This case underscores the importance of considering rare diagnoses like primary liver mesothelioma.
- Recurrence and metastasis highlight the aggressive nature and complex management of this rare liver cancer.
