Osteosarcoma of the larynx.

ABSTRACT

About 11,600 cases of laryngeal cancer were reported in the United States in 1995, accounting for 1% of all reported cancers. Fewer than 1% of laryngeal cancers are sarcomas, osteosarcoma being the rarest type. Twelve cases of laryngeal osteosarcoma have been cited in the literature. A 47-year-old man presented with hoarseness following a benign vocal polypectomy. The entire larynx appeared swollen, although both vocal folds moved well. Biopsies did not reveal pathologic tissue. Computed tomographic imaging revealed a destructive, expansile lesion of the thyroid cartilage. A computed tomography-guided biopsy of this cartilage revealed a high-grade sarcoma. Laryngeal osteosarcoma was diagnosed following total laryngectomy. Laryngeal osteosarcoma is a highly malignant neoplasm with early hematogenous spread. Survival statistics for peripheral osteosarcoma are poor. Limited experience reveals that a combination of surgery and radiotherapy with adjuvant chemotherapy can offer some palliation. The literature and published cases of laryngeal osteosarcoma are reviewed.
