Recurrent benign solitary intraosseous schwannoma of the tibia.

Abstract

Schwannomas (neurilemmomas) are benign neoplasms composed of well-differentiated Schwann cells and are usually found in the soft tissues. The occurrence of schwannomas in bone is rare, accounting for less than 0.2% of primary bone tumors. Most cases of osseous schwannoma reported in the world medical literature involve bones of the skull. Only 2 cases have previously been described in the tibia, neither of which has recurred. We report the first case of a recurrent benign solitary intraosseous schwannoma of the tibia, and detail the clinical, radiological and histological findings.
