[Two cases of cancerization of esophageal stenosis due to a caustic burn].

The incidence of carcinoma of the esophagus within patients with chronic esophageal stricture caused by ingestion of corrosive agents is reported to be significantly higher than in the general population. Two patients developped carcinoma of the esophagus respectively 25 and 40 years after corrosive injury. One of these patients had initially gastrostomy and repeated esophagal dilation.
