A case of pharyngoesophageal diverticulum (Zenker's diverticulum) is presented with special reference to endoscopic findings, and the care of endoscopic examination is discussed. The authors also discussed the error of the triangular of Laimer as location of Zenker's diverticula. The authors point out that many other authors mistook the Lannier-Hackerman spatium from which the Zenker's diverticulum arises, for triangular of Laimer.
