“…Neurilemmoma in the nasal cavity is thought to originate from the ophthalmic branch, maxillary branch, or autonomic ganglion of the trigeminal nerve. [3] Cases in this report included tumors in the lower part of the nasal vestibule; thus, the tumors might have originated from the lower ophthalmic branch of the maxillary Yoo and Yun [2] F/51 Left 1.4 Palpable mass nasal obstruction ND Simple excision ND ND ND Ko et al [4] F/47 Left 0.7 Palpable mass ND Simple excision ND ND No Boo et al [5] M/48 Left 2 Palpable mass nasal obstruction epistaxis (À)…”

“…Neurilemmoma occurs predominantly in the head and neck region, and the incidence of tumors involving the nasal cavity or sinuses is rare, with only 4% of all cases [1] . Of these, neurilemmoma of the nasal vestibule is extremely rare, and only six cases have been reported nationally to date [2–7] . We experienced two cases of neurilemmoma in the left nasal vestibule in a 32-year-old male patient and a 42-year-old female.…”

Rationale:Neurilemmoma is a benign tumor derived from the Schwann cells of the nerve sheath. The highest incidence of neurilemmoma occurs in the head and neck region; however, the nose and paranasal sinuses are rarely involved. Less than 4% of these tumors involve the nasal cavity and paranasal sinuses. To date, only six cases of nasal vestibule neurilemmoma have been reported.Patient concerns:Two patients (a 32-year-old man and a 42-year-old woman) visited our clinic with complaint of a lump in the left nasal vestibule.Diagnosis:Histopathological examination and immunohistochemical staining confirmed a neurilemmoma.Interventions:The mass was completely removed via an intranasal approach.Outcomes and Lessons:Neurilemmoma is easy to overlook because it occurs rarely in the nasal vestibule, but neurilemmoma needs to be considered as a differential diagnosis.
