Malignant transformation of heterotopic pancreas as middle esophagus adenocarcinoma—A rare case report and comprehensive literature review

Abstract

Abstract Heterotopic pancreas is a rare congenital abnormality that occurs during the growth and development process. It can be found in any part of the digestive tract, but the most common sites are the stomach, duodenum, and jejunum. Malignant transformation especially in the esophagus is rare. Here, we aim to report an unusual case of mid‐esophageal adenocarcinoma that originated from a heterotopic pancreas.
