The inner lining of the esophagus is known as the mucosa. It is called squamous mucosa when the top layer is made up of squamous cells. Squamous cells are flat cells that look similar to fish scales when viewed under the microscope. Most of the esophagus is lined by squamous mucosa. Goblet cells normally line the intestines, not the esophagus. When goblet cells are found in a place where they are not supposed to be, like the lining of the esophagus, it is called intestinal metaplasia. Intestinal metaplasia can develop any place where squamous mucosa is normally found.
