[Primary hepatic sarcomatoid carcinoma, an unusual case]

Area of Science:

• Hepatology
• Oncology
• Pathology

Background:

• Primary hepatic sarcomatoid carcinoma is a rare (0.4-0.7%) but aggressive liver tumor.
• It is more common in Asian populations and associated with chronic liver disease from hepatotropic viruses.

Observation:

• This case involves a 72-year-old Korean male with a history of Hepatitis B virus-related chronic liver disease.
• The patient presented with primary hepatic sarcomatoid carcinoma that had metastasized to bone and lymph nodes.

Findings:

• Histological examination reveals both sarcomatous and carcinoma components.
• The tumor lacks distinct clinical or imaging features, necessitating diagnosis through pathological and immunohistochemistry analysis.

Implications:

• Early-stage diagnosis and surgical intervention may offer survival benefits for primary hepatic sarcomatoid carcinoma.
• This case highlights the aggressive nature and metastatic potential of the disease, even in patients with underlying liver conditions.
