摘要
Neurilemmomas is usually a benign neoplasm which is composed of Schwann cells, alsonamed schwannomas and originates from the peripheral nerve sheath. It most frequently （25%- 45%） occurs in the head and neck, but rarely （4%） in the nasal cavity and paranasal sinuses, especially rare in nasal vestibule. In English literature, only Alessandrinis reported one case with the tumor originating from the nasal vestibule. Here we report two cases.
