  • Title: Chondrosarcoma of the temporal bone and otosclerosis.
    Author: Ramírez-Camacho R, Pinilla M, Ramón y Cajal S, García Berrocal JR, Vicente J.
    Journal: ORL J Otorhinolaryngol Relat Spec; 1998; 60(1):58-60. PubMed ID: 9519385.
    Abstract:
    Chondrosarcoma constitutes 6% of all primary bone tumors and 11% of malignant primary bone tumors. Nevertheless, in a review of the tumor registry of the University of Michigan covering a period of 50 years, there were only 3 cases involving the temporal bone. A case of a woman with a chondrosarcoma of the temporal bone that was partially resected by means of an infratemporal approach at the skull base is presented. This patient had previously undergone surgical treatment for otosclerosis of the other ear. Several considerations regarding survival factors in this type of tumor are dealt with in terms of the histological features, therapeutic options and anatomic location. The possibility that this lesion may originate from the persistence of the cartilaginous inclusions that some authors consider to be involved in the origin of otosclerosis is discussed.
