Schwannomatosis is an extremely rare genetic disorder closely related to the more-common disorder neurofibromatosis (NF). Originally described in Japanese patients, [ 1 ] it consists of multiple cutaneous schwannomas , central nervous system tumors, and other neurological complications, excluding hallmark signs of NF.
Schwannomatosis is caused by various mutations on chromosome 22. [4] Neurofibromatosis is an autosomal dominant disorder, which means only one copy of the affected gene is needed for the disorder to develop. [4] If one parent has neurofibromatosis, his or her children have a 50% chance of developing the condition as well.
[6] [7] The correlation with schwannoma predisposition disorders like NF2 and schwannomatosis, however, is minimal (approximately 5 percent of cases). [8] These tumors might lack a capsule or be less encapsulated than a typical schwannoma.More challenging to identify from MPNST are the infrequent plexiform schwannomas that develop in deep ...
Most peripheral nerve tumors occur for unknown reasons. Some, including schwannomatosis and neurofibromatosis (types 1 and 2), are associated with recognized hereditary disorders. Others may be caused by gene mutations. In the case of schwannomatosis and neurofibromatosis, tumors can grow on or close to nerves anywhere in the body.
Neurofibromatosis type II (also known as MISME syndrome – multiple inherited schwannomas, meningiomas, and ependymomas) is a genetic condition that may be inherited or may arise spontaneously, and causes benign tumors of the brain, spinal cord, and peripheral nerves.

The Children's Tumor Foundation (CTF) is a 501(c)(3) foundation dedicated to improving the health and well-being of individuals and families affected by NF, a group of genetic conditions known as neurofibromatosis or schwannomatosis.
Presence of multiple lesions is associated with genetic conditions including neurofibromatosis type 1, neurofibromatosis type 2, and Schwannomatosis. [1] [3] [4] Most spinal schwannomas are intradural-extramedullary, growing inside the thecal sac, but outside the spinal cord itself. [5]
