[Adult hepatoblastoma]

Area of Science:

• Hepatobiliary pathology
• Pediatric oncology (adult presentation)

Background:

• Hepatoblastoma is a rare malignant liver tumor, predominantly affecting children.
• Adult hepatoblastoma is exceptionally rare, posing diagnostic and therapeutic challenges.

Observation:

• A 47-year-old female presented with a confirmed case of hepatoblastoma.
• Microscopic examination revealed a tumor composed of embryonal and fetal cell types.

Findings:

• Immunohistochemical analysis demonstrated expression of low-molecular cytokeratins.
• Positive staining for S-100 protein and hepatocyte antigen was also observed.

Implications:

• This case highlights the importance of considering rare diagnoses in adult liver masses.
• Understanding the cellular and molecular characteristics aids in accurate diagnosis and potential therapeutic strategies.
