research Beyond Coincidence in Neurofibromatosis Type 1: Becker Nevus Adjacent to Plexiform Neurofibroma with Brachial Plexus Involvement and Integrated Mechanistic Illustration
This article presents a rare pediatric case of Neurofibromatosis type 1 (NF1) with a Becker nevus (BN) adjacent to a plexiform neurofibroma (PN) involving the brachial plexus. A 12-year-old girl exhibited a hyperpigmented lesion with features consistent with both BN and PN, confirmed through genetic testing and imaging. The study explores the potential mechanistic link between NF1 and BN, suggesting that somatic "second-hit" mutations and neurofibromin deficiency may lead to melanocyte hyperactivation, contributing to the development of such lesions. This case provides insights into the cellular and molecular dynamics of NF1-related lesions, highlighting the need for further research.
