We described a 56-year-old male who was admitted to the hospital due to no sweat on the right side of face for 4 years, and paraesthesia pharynges for 1 month. The physical examination was carried out. And the horizontal local uplift on right lateral wall of pharynx was found with café-au-lait spot scattered all over the right arm. MRI showed a rounded mass on the right parapharyngeal space with clear boundary. Later the tumor was removed by a transoral route with the assist of endoscope. The patient was eventually diagnosed with neurofibromatosis 1 and did not relapse after follow-up.
