Abstract

Cystic dystrophy is an uncommon, benign poorly understood disease. It is characterized by the development of cysts in heterotopic pancreatic tissue. A 57-year-old-man was hospitalized for abdominal pain for a week. He is a heavy alcohol drinker. There was a cyst at second portion of duodenum on CT. Under the impression of peptic ulcer perforation, Whipple’s operation was performed. Grossly, a cystic space, measuring 3.0 cm in diameter, was noted within the thickened duodenal wall. Microscopically, the cyst was lined by columnar epithelium and granulation tissue and embedded in ectopic pancreatic tissue. The adjacent pancreatic tissue showed focal chronic pancreatitis.
