-Etiology: The cause of schwannomas is not fully known.

-Genes involved: SMARCB1, LZTR1 genes.

-Pathogenesis: The sequence of events that lead to schwannomas loss of function of the merlin caused by genetic alteration or its inactivation leading to growth of schwannomas.

-Morphology: The morphology associated with schwannomas shows well-circumscribed masses on the nerve.

-Histology: The histology associated with schwannomas shows the presence of Antoni A, Antoni B, and verocay bodies.
