title: Angiosarcoma arising from malignant schwannoma in a patient with neurofibromatosis.
abstract: A 20-year-old man with von Recklinghausen disease had a right neck mass. Pathologic examination at excision showed angiosarcoma arising in a malignant schwannoma of the cervical brachial plexus. Comparison with previous reports revealed that angiosarcoma is a rare, highly aggressive sarcomatous element in malignant schwannoma arising in patients with neurofibromatosis (NF).
