Neonatal Soft Tissue Sarcoma with YWHAE-NUTM2B Fusion

Area of Science:

• Oncology
• Genetics
• Pediatric Medicine

Background:

• Neonatal soft tissue sarcomas are rare and diverse tumors.
• The YWHAE-NUTM2B fusion gene is typically found in adult sarcomas, not typically in neonatal cases.

Observation:

• A case of neonatal round-cell sarcoma with the YWHAE-NUTM2B fusion gene is presented.
• The infant received neoadjuvant chemotherapy and surgical resection shortly after birth.

Findings:

• The YWHAE-NUTM2B fusion transcript, previously identified in other sarcoma types, is described in a neonatal small round-cell sarcoma.
• Despite aggressive treatment, the patient experienced a rapid and fatal clinical course.

Implications:

• This case highlights the potential for YWHAE-NUTM2B fusion in neonatal soft tissue sarcomas.
• Further research is needed to understand the clinical behavior and treatment strategies for this rare genetic translocation in newborns.
