title: [Endoscopic-histological differential diagnosis of rare benign endolaryngeal proliferations (author's transl)].
abstract: In the period from 1961 to August, 1975, 2,222 microlaryngoscopic examinations were carried out at the ENT Department of the University. A correlation was seen between the increase in the number of examination in the last few years and the increase in the number of malignant tumours of the larynx, while malignant growths in the hypopharynx were found to be only slightly increased. An anlysis of 1,027 microlaryngoscopies carried out under anaesthesia over the last 2 2/3 years showed almost 50% cancers and precancers. In 5% of the case at most more rare laryngeal findings were also seen. Of these, the granular cell tumour, plasmocytoma, oncocytic cystadenoma and amyloid-tumour of the larynx, but also tuberculous laryngitis, are represented. The modern endoscopic examinations and the fundamental bioptic histomorphological examination of proliferations allow an exact differentiation of these changes in the tissues of the endolarynx. In this connection, a valuable technical aid is the v. Stuckard low-power magnifying laryngoscope, that has been in use for the past six months.
