Case of schwannomatosis

The Journal of Dermatology, 2009
AbstractA 40‐year‐old man presented to our hospital with painful tumors in his left carotid space and left knee. He had no family history of neurofibromatosis type II (NF II), no history of hearing loss or vestibular problems, and no symptoms of NF I.

Neurofibromatosis and Schwannomatosis

Seminars in Neurology, 2018
Neurofibromatosis 1, neurofibromatosis 2, and schwannomatosis are a group of related classically inherited but often times sporadic tumor suppressor syndromes. Neuro-oncologists should recognize these syndromes, initiate necessary tests in patients with a clinical suspicion, and support genetic counseling of patients and families.

Schwannomatosis

Neurology, 1996
Schwannomas are benign nerve sheath tumors that most commonly occur singularly in otherwise normal individuals. Multiple schwannomas in a single patient are most often seen in neurofibromatosis 2 (NF2), but several recent reports suggest that schwannomatosis may also be a distinct clinical entity.

Brigatinib in NF2-Related Schwannomatosis with Progressive Tumors.

New England Journal of Medicine
BACKGROUND NF2-related schwannomatosis (NF2-SWN, formerly called neurofibromatosis type 2) is a tumor predisposition syndrome that is manifested by multiple vestibular schwannomas, nonvestibular schwannomas, meningiomas, and ependymomas. The condition is

Surgical management of schwannomas in schwannomatosis: a comprehensive analysis of clinical outcomes and determinants of local recurrence.

Neurosurgical Focus
OBJECTIVE Schwannomatosis is a rare genetic predisposition to develop multiple nonintradermal schwannomas affecting the spine and peripheral nerves, excluding vestibular schwannomas.

Schwannomatosis, sporadic schwannomatosis, and familial schwannomatosis: a surgical series with long-term follow-up

Journal of Neurosurgery, 2011
Object The aim of this study was to provide disease-specific information about schwannomatosis in its different forms and to present 2 particular cases of malignant schwannomas in the context of familial schwannomatosis (FS). Methods The authors analyzed patients with pathologically defined schwannomas and identified those with varied forms of ...

Schwannomatosis: The Overlooked Neurofibromatosis?

American Journal of Roentgenology, 2013
Schwannomas are typically benign tumors that occur sporadically, in neurofibromatosis type 2 (NF2), or in an entity called "schwannomatosis." Schwannomatosis patients develop multiple schwannomas without involvement of the vestibular apparatus. Geneticists, neurologists, and pathologists have recognized that schwannomatosis is distinct from NF2, but ...

Diagnostic criteria for schwannomatosis

Neurology, 2005
The neurofibromatoses are a diverse group of genetic conditions that share a predisposition to the development of tumors of the nerve sheath. Schwannomatosis is a recently recognized third major form of neurofibromatosis (NF) that causes multiple schwannomas without vestibular tumors diagnostic of NF2.

Schwannomatosis: a Realm Reborn: year one

Current Opinion in Oncology, 2023
Purpose of review In 2022, an international consensus recommendation revised the nomenclature for neurofibromatosis type 2 (NF2) and Schwannomatosis (SWN), now grouped under the umbrella term Schwannomatosis, and defined new diagnostic criteria. Recent findings This review describes

Surgical Management of Peripheral Nerve Schwannomas in Non-Neurofibromatosis Type 2 Schwannomatosis.

Operative Neurosurgery
BACKGROUND AND OBJECTIVES Pain is the cardinal symptom of non-neurofibromatosis type 2 schwannomatosis (non-NF2-SWN), and peripheral nerve schwannomas are the most frequent tumors encountered in this condition.
