Key words:

Malignant schwannoma.

ABSTRACT

The orbit is richly innervated by branches of the oculomotor nerves, sympathetic and parasympathetic fibers, and sensorial fibers of the first and second branches of the trigeminal nerve. Most of the tumors of nervous outlying sheath correspond to 4% of the orbital tumors, and of these, near 1% belongs to isolated neurofibromas, other 1% to schwannomas. This essay discusses the case of a woman who went to consultation because of hemifacial pain and left ocular proptosis. Because of the clinical and paraclinical discoveries, the patient was subjected to surgery with the purpose of carrying out an excisional biopsy of the lesion, whose anatomopathologic analysis demonstrated the proliferation of neoplasic cells. The rarity of the presentation of the tumor is also discussed.
