Abstract
Schwann cells are responsible for the production of the myelin sheath around the axons of the peripheral nervous system. Benign neoplasms which originate from Schwann cells are hence termed Schwannomas or Neurilemmomas. They present as slow-growing, solitary, encapsulated, benign masses usually in association with nerve trunks. Schwannomas are relatively rare tumors with 25-45% occurring in the head and neck region. These case reports aim to describe the presentations, work-up, and treatment of two patients with head and neck schwannoma in atypical locations. Both patients had a history of gradually increasing swelling, the first originating from the sino-nasal region and the second from the temporal/ infratemporal region. Complete surgical excision of the tumor was done in both cases with no reported recurrence at 18months follow-up. The final diagnosis was made based on histopathology and immunohistochemistry findings. Schwannomas often present a diagnostic dilemma and should be considered a possibility in all head and neck tumors. Recurrence is rare.
