Abstract

|
A heterotopic pancreas in the gastrointestinal tract is mostly found incidentally and its malignant transformation is extremely rare. We describe the second case of ade-nocarcinoma arising in a gastric heterotopic pancreas of an asymptomatic 35-yr-old man in Korea. Esophagogastroduodenoscopy revealed a submucosal tumor with an irregular central umbilication in the gastric antrum. A wedge resection specimen demonstrated a submucosal oligolocular cystic mass (1.7 ×1.4 ×1.2 cm) with a solid portion. Microscopically, the cystic portion was composed of dilated pancreaticobil-iary type ducts with adjacent small foci of periductal glandular structures. The ade-nocarcinoma components in the solid area infiltrated the proper muscle and the over-lying mucosa of the stomach. The transitional area between the benign ductal struc-tures and the adenocarcinoma component was found. The follow-up course was uneventful 5 months postoperatively.
