An unusual case of ectopic pancreas mimicking gastrointestinal stromal tumor of the stomach

Abstract

Ectopic pancreas is a congenital heterotopic pancreatic tissue typically found in the gastric antrum incidentally. It is easily recognized by its small cratershaped appearance near pylorus on endoscopy. However, it may appear as large submucosal lesion in rare cases. It may not be possible to differentiate ectopic pancreas from stromal tumor and leiyomyoma in all cases even by tomography or endoscopic ultrasound. We report an unusual case of ectopic pancreas which appeared as submucosal lesion on endoscopy and diagnosed by surgical resection.

Keywords

Gastrointestinal stromal tümörü taklit eden sıradışı bir gastrik ektopik pankreas olgusu

Öz

Ektopik pankreas genellikle mide antrumunda tesadüfen tespit edilen konjenital heterotopik pankreas dokusudur. Endoskopide, pilora yakın küçük krater şeklinde görüntüsüyle kolayca tanınır. Ancak nadir durumlarda büyük submukozal lezyon olarak ta izlenebilir. Tomografi ve endoskopik ultrasonografiyle bile stromal tümörler ve leiyomiyomdan ayırt edilmesi her zaman mümkün olmayabilir. Bu yazıda, üst endoskopide antrumda submukozal lezyon olarak değerlendirilip cerrahi rezeksiyon sonucu tanı alan sıradışı bir ektopik pankreas olgusu sunulmaktadır.
