[Orbital schwannoma in a child with acute proptosis].

Schwannoma is a usually benign primary tumor. It develops from the Schwann cells, which produce the myelin sheath that surrounds the peripheral nerves. It represents less than 10 % of the intracranial tumors, and it is infrequent in the pediatric age. We hereby present a 6-year-and-11-month-old previously healthy patient, with a history of intermittent generalized cephalea associated with proptosis and a diminished visual acuity of the left eye, epiphora and strabismus, with radiological evidence of retro-ocular mass. A macroscopically complete exeresis was performed, with an anatomopathological diagnosis of orbital schwannoma.
