Summary

Dear Editor,

Schwannomas are benign nerve sheath tumours composed of neoplastic cells with schwannian differentiation, of which several morphological variants have been described. Neuroblastoma-like schwannoma is an exceptionally rare subtype defined by the presence of rosette-like structures composed of neoplastic Schwann cells surrounding a collagenous core. We describe a case of neuroblastoma-like schwannoma (schwannoma with rosette-like structures) also exhibiting a plexiform growth pattern; such combined features have been rarely reported so far.
