Background: To our knowledge, There are only 7 cases of posterior pharyngeal wall schwannoma which have been previously reported in the literature, but none of them was associated with a 3-year-old child.
Case presentation: We presented a rare case of a schwannoma which is localized on the posterior pharyngeal wall, It caused severe difficulty in swallowing and breathing in a child whose age is three years old. Schwannomas of the posterior pharyngeal wall has been rarely reported in children, The tumor was removed with plasma radio frequency excision via a transoral route, There was not seen any recurrence of tumor by examination of CT or MRI up to two years. as far as we know, It's the first time which a case of posterior pharyngeal wall schwannoma that has been reported to occur in a 3-year-old child, and the first case in which the schwannoma was removed via transoral plasma radio frequency excision.
Conclusions: This case illustrates that schwannoma may be found in children ,and it is safe to treat this disease through plasma radio frequency excision via a transoral route.
