Squamocolumnar junction (left) was located 15 cm above the esophagogastric
junction. View on the right shows a long segment of esophagus covered with
columnar epithelium.
Left: 47 year-old woman with chronic pyrosis (heartburn). Endoscopy
demonstrated an irregular squamocolumnar junction, with bands of metaplastic
epithelium extending proximally. Right: 73 year-old woman with pyrosis
and dysphagia (difficulty swallowing). Squamocolumnar junction shown here was
located 10 cm above the junction of the stomach and esophagus.
