Intramedullary schwanommas are rare, and most cases are reported in cervical region. Less than 20 dorsal intramedullary schwanommas have been reported till date in literature. This is due to their cell of origin, the Schwann cell, which is not normally found within the parenchyma of the brain and spinal cord; therefore it is not surprising that these lesions are rare. We report a rare solitary dorsal intramedullary schwanomma in a young adult patient who presented with paraplegia.

Schwannoma or neurilemmomas are benign, encapsulated, slow growing nerve sheath tumors of ectodermal origin derived from schwann cells of the nerve sheath. It is commonly seen in the head and neck region. It mainly arises from vestibulocochlear nerve (80%) and rarely in oral cavity (1%), tongue being the most common site in the oral cavity. Palate is a rare site for schwannoma. Herein, we report a rare case of schwannoma of the hard palate in a 21-year-old male. It was excised intraorally. A histopathological diagnosis of schwannoma was made. Immunohistochemistry with S-100 and vimentin were positive which confirmed the diagnosis of schwannoma.
