Primary hepatic sarcoma is rare and can mimic chronic expanding hematoma (CEH). This case highlights that hepatic lesions resembling CEH may develop into undifferentiated sarcoma (US), emphasizing the need for vigilance.
Area of Science:
- Hepatobiliary Surgery
- Surgical Pathology
- Oncology
Background:
- Primary hepatic sarcoma is an exceedingly rare malignancy in adults.
- Distinguishing hepatic sarcoma from benign hemorrhagic lesions on imaging can be challenging.
- Undifferentiated sarcoma (US) can present atypically, mimicking other conditions.
