Abstract

We report a case of chondrosarcoma of the larynx, diagnosed by a percutaneous core-needle biopsy (CNB). Cartilaginous tumors of the larynx are usually diagnosed by biopsy with direct laryngomicroscopy under general anesthesia. However, patients find it difficult to undergo a biopsy under general anesthesia, for physical, economic, and social reasons. Instead, we can readily detect and sample tumors of the larynx using ultrasound under local anesthesia with reduced stress. Concerning needle-puncture biopsies, including fine-needle aspiration cytology (FNAC) and CNB, some studies have reported needle track dissemination, a possible complication in patients with malignant tumors. Thus, in the head and neck region, we generally use FNAC for biopsies, not CNB. However, it can be difficult to diagnose bone tumors by cytology alone. Regarding primary bone tumors, only one study has reported needle track dissemination by CNB, in osteosarcoma of the femur. Additionally, this complication has not been reported before with chondrosarcoma anywhere in the body. To our knowledge, this is the first report concerning chondrosarcoma of the larynx diagnosed by percutaneous CNB. We recommend CNB as a useful and safe diagnostic technique for primary bone tumors in the head and neck region.
