Chondrosarcoma of the temporal bone. Diagnosis and treatment of 13 cases and review of the literature

Cancer. 1986 Dec 15;58(12):2689-96. doi: 10.1002/1097-0142(19861215)58:12<2689::aid-cncr2820581224>3.0.co;2-p.

Abstract

Chondrosarcoma of the temporal bone is a rare lesion. Clinically it has been confused with multiple sclerosis, glomus jugulare tumors, meningioma, and chordomas. The cranial nerve palsies frequently observed with the tumors are related to the anatomic locations of the tumors. Thirteen patients with this entity are presented and the eleven other cases in the literature are reviewed. Histologically the tumors are low grade and exhibit myxoid features. The myxoid features must be differentiated from chordoma and chondroid chordoma. The tumor locations preclude surgical excision and conventional radiation therapy can cause unacceptable neurologic sequelae. Proton beam therapy has been effective in short-term results and appears capable of avoiding serious neurologic side effects.
