Solitary Hybrid Neurofibroma-Schwannoma of the Brachial Plexus in a 4-Year-Old Child

We report the case of a 4-year-old child with a rare solitary neurofibroma-schwannoma hybrid tumor in the brachial plexus, not associated with known syndromes. Surgical management through a transclavicular approach enabled complete tumor excision with favorable postoperative outcomes. Histopathology and immunohistochemistry confirmed the tumor's hybrid nature.
