Intraosseous Nerve Sheath Tumors in the Jaws
Although the head and neck region is recognized as the most common location for peripheral nerve sheath tumors, central involvement, particularly in the jaw bones, is quite unusual. Neurofibroma is one of the most common nerve sheath tumors occurring in the soft tissue and generally appears in neurofibromatosis 1 (NF1 or von Recklinghausen's disease).

متن کاملHead and Neck Nerve Sheath Tumors: A 10-Year Evaluation in Iran
Background and Objective: Approximately 45% of benign peripheral nerve sheath tumors (PNST) occur in head and neck regions. Malignant peripheral nerve sheath tumors (MPNST) are less common and only 8-15% of these tumors occur in head and neck region. In this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family h...
متن کاملMalignant Peripheral Nerve Sheath Tumors (MPNST)
INTRODUCTION Malignant peripheral nerve sheath tumors (MPNSTs) are sarcomas which originate from peripheral nerves or from cells associated with the nerve sheath, such as Schwann cells, perineural cells, or fibroblasts. Because MPNSTs can arise from multiple cell types, the overall appearance can vary greatly from one case to the next. This can make diagnosis and classification somewhat difficu...
متن کاملHybrid peripheral nerve sheath tumors: A review.
Hybrid peripheral nerve sheath tumors (HPNST) are relatively recently described tumors. With ongoing research, a considerable amount of important findings have been made, much of which has substantial clinical implications. However, a comprehensive review of the whole topic has not been published in the literature so far. In the presented manuscript, the various hybrid tumors are discussed sepa...
متن کاملCentral Mandibular Nerve Sheath Myxoma
Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement...
