The purpose of this study is to investigate the distribution and the direction of fibers in nasal polyps. The distribution of fibers is not well known about position and quantity. From June 1993 to April 1996, the authors obtained 232 nasal polyps from 191 patients. The polyps had been stained with H-E method. Authors observed the histopathologic type of polyps, and then the polyps have been stained with Weigert's method getting information about the fibers of polyps. In the polyps, the origin site of polyp showed dense collagen fibers of which direction resembled the movement of sand in hour-glass. In the submucosa, the direction of fibers is parallel to epithelium. Each gland or grouped glands in the polyps were circumscribed with collagen fibers. Our current study on the fibers and glands in nasal polyps is very fundamental, but we suggest that further investigation about the fibers and glands in polyps would enable to reveal pathogenesis of polyp investigated.
