[Pulmonary papillomatosis].

The authors report a case of a 30 year old woman with juvenile laryngeal papillomatosis (JLP) who subsequently developed intra-alveolar papillomas. These papillomas demonstrated a marked pseudo-neoplastic loco-regional invasive activity, but did not possess the histological criteria of malignancy and were treated by pneumonectomy and lobectomy.

[Use of a laser beam (YAG) with a flexible fiber for endoscopic treatment of some broncho-tracheal lesions (author's transl)].

For several years we employed an endoscope permitting electro-coagulation in the treatment of some broncho-tracheal lesions and were able to observe the limits and accidents involved in this method. When compared with clinical results (work of Freche in ORL, laser CO2) and after experimental research, the use of a flexible laser beam (YAG) seems to bring about a noteworthy increase in therapeutic possibilities. This flexible fiber beam could easily be used by some medico-surgical teams who already possess appropriate of easily adaptable endoscopic equipment.
