Chondrosarcoma of the larynx.

A case of a low grade chondrosarcoma of the cricoid cartilage which had been diagnosed initially as a chondroma is presented. The tumour recurred twice after limited surgical resections. Total laryngectomy was inevitable due to near total involvement of the cricoid cartilage and subsequent histological examination revealed a low grade chondrosarcoma.

[Primary bronchogenic and pharyngo-laryngeal carcinomas (author's transl)].

The study of 112 case histories of lung cancers, both primary and secondary, has allowed the authors to determine as being of 5% the incidence of primary bronchogenic carcinoma associated with treated pharyngo-laryngeal cancer. One out of three such primaries was a solitary lung opacity. Bronchogenic primaries appeared be almost as frequent as lung, pleura and mediastine secondarie.

[Primary pharyngolaryngeal carcinoma, pulmonary metastases and carcinoma of the bronchus (author's transl)].

On the basis of 112 cases of pulmonary or mediastinal neoplasms observed during the treatment or follow-up of 952 carcinomas of the pharynx and larynx, the authors study in detail 45 cases of metastases. They draw the following conclusions:--metastases present clinically relatively early in the treated course of pharyngolaryngeal carcinomas: 85% before 18 months.--cannonball lesions are the commonest endo-thoracic clinical metastases: 6 out of 10.
