Neurofibromas are occasionally present in spinal roots; however, an intramedullary neurofibroma is especially rare. Although a few cases of intramedullary neurofibromas in cervical spinal cord have been reported, to the best of our knowledge, there are no reports of intramedullary neurofibromas in thoracic spinal cord, and moreover, no reports have clearly reported immunohistochemical findings....

Received January 2006 Accepted December 2006 INTRODUCTION Neurofibromas are tumors originating from the Schwann cells in the neural sheath of the cranial, peripheral, and visceral nerves. The gross appearance of neurofibromas varies greatly in different lesions. Superficial tumors appear as small, soft, pedunculated, or sessile nodules protruding from the skin. But, deeper tumors are larger. Tu...

Patients with neurofibromatosis type 1 (NF1), one of the most common genetic disease affecting the nervous system, develop multiple neurofibromas that can transform into aggressive sarcomas known as malignant peripheral nerve sheath tumors (MPNSTs). Studies of human tumors and newly developed transgenic mouse models indicate that Schwann cells are the primary neoplastic cell type in neurofibrom...

Traumatic neuroma, neurofibroma, neurilemmoma, palisaded encapsulated neuroma and malignant peripheral nerve sheath tumor (MPNST) are peripheral nerve sheath tumors and present neural origin. The goal of this study was to describe the epidemiological data of oral peripheral nerve sheath tumors in a sample of the Brazilian population. Biopsies requested from the Oral Pathology Service, School of...

Neurogenic neoplasm of the larynx is rare. Especially, neurofibroma of the vocal fold has not been reported in the Japanese literatures. This paper describes a case of neurofibroma of the vocal fold. The patient was a 64-year-old man. He first developed hoarseness in November 1977. In June 1978, he noticed occasional inspiratory dyspnea. He was first seen by another laryngologist and a mass of ...

Malignant peripheral nerve sheath tumor (MPNST) is a rare tumor that is one of the most aggressive malignant lesions in the head and neck area. The majority of MPNSTs arise de novo or from malignant transformation of pre-existing neurofibromas, particularly in individuals with neurofibromatosis type 1 (NF1). However, solitary neurofibromas without an association with NF1 seldom recur after exci...

A rare case of caruncular neurofibroma in a patient who did not have neurofibromatosis. To remember peripheral nerve sheath tumours in the differential diagnosis of caruncular lesions. Excisional biopsy proved to be adequate treatment in our case.

The authors report a rare case of a pulmonary neurofibroma treated by surgical excision. The case report is accompanied by a review of the literature and the discussion of the diagnostic problems posed by neurogenic tumors of the thorax.
