Adenomatous residue in cancerous papilla of Vater.
Abstract
Surgical specimens of carcinoma in the papilla of Vater were studied histologically. Adenomatous residue which suggested that the carcinoma was derived from a pre-existing adenoma was found in 18 cases (81.8%) out of 22. The histological transition of adenoma into carcinoma was also frequently seen.
