Malignant peripheral nerve sheath tumour metastasising to the parotid gland

Two rare cases of metastases from malignant peripheral nerve sheath tumours (MPNST) of the head and neck are described. The initial lesions were superficial, but despite early diagnosis and complete excision, they metastasised to the ipsilateral parotid gland. Both underwent further complete excision and neither metastatic lesion showed progression in grade. One patient is alive, however, the other died of widespread metastases. There are no other reported cases of these sarcomas in the head and neck metastasising to the parotid gland.
