Morphological findings in peptic esophageal stenosis with Barrett's ulcer in children.

The morphological findings in three resected specimens of Barrett's ulcer in children are discussed. Nearly identical morphologic changes are found in all cases, even in adults. This pathologic condition is understood as the third or fourth stage of reflux esophagitis. Perforation or even malignant degeneration is described in these cases. Therefore mainly all therapeutic aims must be to prevent these stages.
