Abstract
Primary malignant schwannomas are rare neoplasms of nerve sheath origin, especially in the location of the head and neck where few cases are described in the literature. These tumours may pose a diagnostic dilemma in the work-up of a neck mass. The case presented here is of a malignant schwannoma that originated in the cervical plexus with the rare histological feature of melanocytic differentiation. Histopathological examination with immunostaining techniques is essential for the diagnosis of these tumours. The management of these neoplasms is still controversial, although the treatment of choice is radical surgical excision of the lesion. The role of postoperative radiotherapy or chemotherapy is not clear, although some authors recommend its use to prevent local recurrence, for unresectable recurrent tumours or in cases of distant metastases.
