Intraosseous schwannoma of the humerus.

Intraosseous schwannomas are rare benign neoplasms of the bone, of which fewer than 200 cases have been described in the world literature. These tumors are well-defined, lytic lesions, rarely associated with pathologic fracture. The mandible is the most frequently involved bone. We present only the third case of an intraosseous schwannoma involving the humerus.
