This is the appearance of the distal esophagus, specifically the area of the gastro-esophageal (GE) junction

Short Segment Barrett's esophagus. The stomach lining (that is salmon-color) has grown up into the esophagus. This is caused by acid reflux disease.

Case Example with Video

The larynx shown below is that of a 60-year-old singer who presented with a 30-year history of chronic cough and intermittent hoarseness. He also had symptoms of post-nasal drip, a sensation of a lump in the throat (globus), and chronic throat clearing.

Examination of the laryngopharynx shows left vocal fold paresis (partial paralysis), laryngopharyngeal reflux, and candida (fungal)  laryngitis. (BTW, the left vocal fold is on the right — the image is reversed, like facing a person.  The right arytenoid crosses the midline to achieve closure. The white specks seen are the fungus.)  Shown below (same patient) is candida esophagitis. Click on larynx above to see the TNE video.
