Bone metastases from squamous-cell carcinoma of the larynx

Four patients are described with distant bone metastases from primary squamous-cell carcinoma of the larynx. In one case the metastases were osteosclerotic, a previously unreported occurrence. The metastases were osteolytic in the other three patients. Bone metastases from laryngeal carcinoma are rare and associated with locally extensive tumours and a poor prognosis.
