title: Malignant peripheral nerve sheath tumour of maxilla.
abstract: Malignant peripheral nerve sheath tumour (MPNST) is a very rare entity in head and neck with high rate of recurrences and local invasiveness. This tumour is usually found in lower extremities and only 10-12% occur in head and neck region. The diagnosis is considered as the most elusive and difficult among soft tissue sarcomas because of its non specific presentation, both clinically as well as pathologically. This difficulty has now been overcome by immunohistochemistry. We report here a case of MPNST in a 50 years old male with a localized right maxillary growth.
