Background:

Synchronous tumors are rare in newborns, posing diagnostic and therapeutic challenges.
Sialoblastoma and hepatoblastoma are distinct pediatric neoplasms with varying prognoses.
Early prenatal diagnosis is crucial for effective management strategies.

Observation:

A newborn presented with synchronous sialoblastoma and hepatoblastoma diagnosed via MRI and US at 20 weeks gestation.
The patient exhibited a large facial tumor with significantly elevated alpha-fetoprotein levels.
Surgical biopsy confirmed both tumor types, with a high Ki67 index in sialoblastoma suggesting aggressive behavior.

Findings:

Complete surgical resection with clear margins is the primary treatment for sialoblastoma.
Multimodal therapy involving surgery and chemotherapy was employed in this complex case.
This case represents one of only a few reported instances of synchronous sialoblastoma and hepatoblastoma.

Implications:

Prompt, multidisciplinary team management is vital for optimizing outcomes in rare synchronous pediatric tumors.
Aggressive sialoblastoma necessitates careful monitoring and potentially intensified treatment protocols.
This case contributes valuable insights into the clinical course and management of rare dual pediatric neoplasms.
