title: [Three cases of intramural cyst of the esophagus with ciliated epithelium].
abstract: We had 3 cases of intramural cyst of the esophagus with ciliated epithelium. In Case 1, 13-year-old man, the cyst was lined with ciliated columnar epithelium and had a smooth muscle layer. In Case 2, 37-year-old female, the cyst was lined with ciliated stratified epithelium and had some layers of smooth muscle. In Case 3, 42-year-old male, the cyst was lined with ciliated columnar epithelium and had a smooth muscle layer. In all cases, cartilaginous tissue was not found. They had no complaints and the abnormal shadow was found by chance Chest X-ray film. When the cyst did not have typical diagnostic criteria, clear division into esophageal cyst or bronchogenic cyst is difficult. The bronchus and the esophagus are of the foregut origin, so we suppose the middle type cyst, between esophageal and bronchial, may exist. In Case 2, the cyst was diagnosed as esophageal, because it had some muscle layers. But in Case 1 and Case 3, as the cyst did not have typical diagnostic criteria, we diagnosed them as the inclusion cyst of the esophagus, not as esophageal, not as bronchogenic.
