[Carcinoma of the esophagus engrafted on corrosive stricture of the esophagus].

A highly significant incidence of esophageal cancer engrafted on corrosive stricture of the esophagus has been statistically evaluated. So far, only 8 cases in Japan and over 100 cases in foreign literatures have been reported. In 1976, we reported the first case of carcinoma of the esophagus associated with corrosive stricture of the esophagus in Japan. Our second case operated in 1975 was pathologically confirmed to be adenosquamous carcinoma of the esophagus which has never been reported in the literatures. In this paper surgical and pathological problems of the carcinoma of the esophagus associated with corrosive stricture of the esophagus were discussed adding to the analysis of 8 reported cases in Japan.
