We report a case of plexiform schwannoma of the posterior pharyngeal wall that occurred in a 37-year-old man who had been previously diagnosed with neurofibromatosis type 2 (NF2). Plexiform schwannoma has been rarely reported in association with NF2. Moreover, as far as we know, only 6 cases of posterior pharyngeal wall schwannoma have been previously reported in the literature, none of which was associated with NF2 and none of which was histopathologically differentiated in schwannoma or plexiform schwannoma. The patient was treated with laser excision of the tumor via a transoral route, and at 6 and 12 months of follow-up, he exhibited no signs of recurrence. To the best of our knowledge, our patient represents the first reported case of a posterior pharyngeal wall schwannoma that occurred in association with NF2 and the first case in which the schwannoma was removed via transoral laser excision. This case illustrates that plexiform schwannoma is a possible finding in NF2 and that transoral laser excision is a safe surgical procedure in such a case.

Introduction And Importance: Schwannomas are benign tumors that arise from Schwann cells commonly located in peripheral nerves. Depending on the size and location of sciatic nerve Schwannoma clinical manifestations can either varies from symptoms simulating radiculopathies such as positive Lasegue sign on the affected side, gait weakness and paresthesia or just present with pain and an associated palpable mass.
Case Presentation: The authors present a case of a 34-year-old female patient suffering from pain, gait weakness, and a palpable mass since many months.
