Histopathological examination following surgical resection confirmed the diagnosis of vestibular schwannoma, and genetic analyses were subsequently performed on the schwannoma, a cutaneous neurofibroma, and peripheral blood from the same patient.<h4>Genetic findings</h4>Whole-exome sequencing revealed a pathogenic germline NF1 mutation shared across all analyzed samples. Here, NF1 is linked to plexiform neurofibroma.
