Esophagus, Stomach & Intestine; A Case of Adenomyoma of Duodenum


Adenomyoma of the gastrointestinal tract has been considered to be a form of pancreatic heterotopia. Heterotopic pancreatic tissue in the gastrointestinal tract is a relatively not uncommon abnormality, but adenomyoma is a rarely reported tumor and its ineidence is difficult to determine. Adenomyoma is similar to aberrant pancreas in both appearance and location, and cannot be differentiated endoscopically or radiographically. Histologically, adenomyoma is primarily composed of smooth muscle and undifferentiated duct like structures. It is usually of no clinical importance and incidentally detected, but according to its location and size of the mass, it may become a serious clinical problem. Its real importance lies in the recognition of its existence, to facilitate a timely diagnosis, We present a case of adenomyoma of the duodenum with a brief literature review.
