Corrosive induced carcinoma of esophagus: report of three patients and review of literature.

Patients with corrosive induced esophageal strictures have more than a 1000-fold risk of developing carcinoma of the esophagus. We report three cases of corrosion carcinoma seen by us (a team of gastroenterologists, radiologists and a surgeon) in the last 15 years. Two cases were among 156 patients with corrosive induced strictures on our follow-up, and constituted the only corrosion carcinoma out of 650 esophageal carcinomas operated on by us.

Multiple squamous cell carcinomas of esophagus.

Multiple tumors of the esophagus are reported only rarely. We describe three patients with double carcinoma of esophagus. They developed a second squamous cell carcinoma of esophagus more than 4 1/2 years after external radiation for a primary squamous cell carcinoma at a different site in the esophagus.
