title: Rhinoscleroma: a scanning electron-microscopic study.
abstract: Nasal biopsies from 6 patients with rhinoscleroma were studied by scanning electron microscopy. Numerous bacilli of different sizes were found on the epithelial surface. Few bacilli with thin spiral terminal cilia were seen over the surface of large protruding non-epithelial cells. These cells appeared to be the Mikulicz cells migrating from the tunica propria to the epithelial surface through small ulcerations. In the tunica propria, Mikulicz cells containing numerous bacilli were observed. In 4 patients, round bodies and long tubular structures were found on the epithelial surface. These bodies were suggested to be fungi, yet their exact nature and their relation to Klebsiella rhinoscleromatitis bacilli need further investigation.
