title: Malignant peripheral nerve sheath tumour of scalp with extradural extension: case report.
abstract: Malignant peripheral nerve sheath tumours are uncommon aggressive soft tissue     sarcomas that originate from peripheral nerves or cells associated with the     nerve sheath. Scalp malignant peripheral nerve sheath tumours are extremely rare     and the role of multimodality management is unclear. We report a 43-year-old     female with scalp swelling and rapid growth. Imaging demonstrated an aggressive     lesion with extradural extension. A wide excision with negative margins was     achieved and he defect reconstructed by rotational flap. The patient was given     adjuvant radiation. A follow-up scan done one year post radiation did not show     any recurrence. Malignant peripheral nerve sheath tumours of the scalp are     extremely rare and such an extradural extension has not been described earlier.
