Objective:

To present a rare clinical case of a large plexiform neurofibroma in neurofibromatosis type 1, emphasizing the significance of genetic findings and their implications for treatment.

Key Findings:
  • Plexiform neurofibromas are observed in up to 30% of NF1 patients and can undergo malignant transformation.
  • The patient exhibited extensive plexiform neurofibromas involving the hepatic hilum and surrounding vessels.
  • Genetic testing revealed a deletion of the first exon of the NF1 gene.
Interpretation:

The case highlights the importance of monitoring and early initiation of targeted therapy in NF1 patients with extensive plexiform neurofibromas.

Limitations:
  • The case is a single patient report, limiting generalizability.
  • Long-term outcomes of the targeted therapy are not yet available.
Conclusion:

The case underscores the need for careful monitoring in NF1 patients with significant plexiform neurofibromas.
