Primary endodermal sinus tumor of the liver detected by CT

Area of Science:

• Hepatology
• Oncology
• Pathology

Background:

• Endodermal sinus tumors (ESTs) are rare germ cell neoplasms.
• ESTs typically originate in the gonads (testis or ovary).
• Extragonadal ESTs are uncommon, with primary hepatic presentation being exceedingly rare.

Observation:

• A case of primary endodermal sinus tumor localized to the liver is presented.
• The tumor was identified using computed tomography (CT) imaging.
• Diagnostic confirmation was achieved through a percutaneous biopsy procedure.

Findings:

• The study confirms a rare instance of primary endodermal sinus tumor arising in the liver.
• CT imaging facilitated the detection of the hepatic neoplasm.
• Percutaneous biopsy provided the definitive histopathological diagnosis.

Implications:

• This case contributes to the limited literature on primary hepatic endodermal sinus tumors.
• Highlights the importance of considering rare differentials in liver mass diagnosis.
• Underscores the utility of advanced imaging and biopsy in diagnosing uncommon hepatic neoplasms.
