Question 1 of 1
1. Question
Week 43: Case 2
This 32-year-old female presented with vague abdominal pain. Imaging revealed a cystic mass in the wall of her stomach./images/6.4.01.RHHcase2a.jpg
/images/6.4.01.RHHcase2b.jpg
/images/6.4.01.RHHcase2c.jpgCorrect
Answer: Ectopic pancreas
Histology: The resected specimen revealed a 3cm cystic mass in the wall of the stomach. This mass was lined by an attenuated epithelial lining. In the wall of the cystic mass, there was well-differentiated pancreatic parenchyma including well-formed acini and islet cells.
Discussion: Ectopic pancreas has been reported in variety of organs. The most common sites are the intestines, the stomach, and Meckels Diverticulum. Foci of ectopic pancreas are often submucosal resulting in a grossly unbilicated mass. Because these foci of ectopic pancreas can produce a variety of digestive enzymes they can lead to ulceration and gastrointestinal bleeding. In this particular case the focus of ectopic pancreas appears to have released its secretions into a well-defined lumen within the wall of the stomach, resulting in the formation of a cystic mass.
