Schwannoma/Neurilemmoma is a benign mesenchymal tumor, contains no neural elements but arises from the nerve sheath or Schwann's cells. Neurilemmoma is encapsulated and exhibits a characteristic histologic pattern known as Antoni type A and Antoni type B with Verocay bodies. The lesion is partially encapsulated but well demarcated from overlying atrophic/ stretched oral mucosa. We present a case of schwannoma occurring in a 60 year old male edentulous patient with a chief complaint of firm, non tender swelling in anterior mandibular region which gradually increased in size. Interestingly, in many areas, traumatic neuromas like proliferations of cells of neural tissue with elongated, wavy nuclei arranged in swirls as well as haphazard manner were noted.

Abstract


Schwannoma/Neurilemmoma is a benign mesenchymal tumor, contains no neural elements but arises from the nerve sheath or Schwann's cells. Neurilemmoma is encapsulated and exhibits a characteristic histologic pattern known as Antoni type A and Antoni type B with Verocay bodies. The lesion is partially encapsulated but well demarcated from overlying atrophic/ stretched oral mucosa. We present a case of schwannoma occurring in a 60 year old male edentulous patient with a chief complaint of firm, non tender swelling in anterior mandibular region which gradually increased in size. Interestingly, in many areas, traumatic neuromas like proliferations of cells of neural tissue with elongated, wavy nuclei arranged in swirls as well as haphazard manner were noted.
