title: A histochemical study of simple laryngeal polyps.
abstract: Benign laryngeal polyps and normal larynxes have been studied by histochemical and other staining methods. These show that the polyps contain much free hyaluronic acid and 6-chondroitin sulphate. Their mode of production may be the mechanical separation of these compounds from collagen fibres by vibration. An alcian-elastic stain may be a helpful diagnostic method.
