A 51-year-old woman admitted for intestinal obstruction had her symptoms ameliorated in conservative therapy but they recurred after eating. Based on a diagnosis of idiopathic intestinal obstruction, we conducted laparotomy, finding a jejunal obstruction 170 cm distal from Treitz's ligament. We resected the part of the jejunum containing the 2.6×2.2 cm tumor. Histopathological findings showed well-differentiated tubular adenocarcinoma originating from a Heinrich type III aberrant pancreas. Gemcitabine hydrochloride administered for peritoneal recurrence delayed her demise until 28 months after initial surgery, suggesting that gemcitabine hydrochloride may be promising in treating aberrant pancreatic cancer as well as primary pancreatic cancer. Aberrant pancreatic cancer in the jejunum is rarely encountered, and we review cases reported in the literature.

Key words
