Malignant peripheral nerve sheath tumor of the superficial cervical plexus with parotid extension

Introduction: Cervical locations of malignant peripheral nerve sheath tumor (MPNST) are rare, at less than 1% of malignant tumors of this region. Case report: A 53-year-old woman presented with a lateral cervical swelling involving the parotid region. Histology was in favor of MPNST. Adjuvant radiotherapy was indicated because of the infiltrating nature of the tumor. At 2 years' follow-up, there was no recurrence. Discussion: Clinical diagnosis is difficult in cervical MPNST. Only histology with immunohistochemistry can establish the correct diagnosis. Treatment requires complete surgical resection and regular clinical follow-up. (C) 2014 Elsevier Masson SAS.
