BACKGROUND: @entity652 is a rarely described @entity5 of the gastric mucosa. Recent publications have shown that similar lesions are also found in the gallbladder, the main pancreatic duct, the duodenum and the cervix of the uterus. Apart from case reports, few clinical data are available on these @entity1 . We therefore conducted a search of the archived material collected between 1990 and 2000 for more clinical data on @entity1 with this rare lesion. @entity1 AND METHODS: Between 1990 and 2000, 90 @entity1 were diagnosed as having a @entity652 in the stomach (77 @entity1 ), duodenal bulb (7 @entity1 ), duodenum (1 @entity1 ), bile duct (3 @entity1 ) or gallbladder (2 @entity1 ). RESULTS: Pyloric gland @entity652 account for 2.7% of all @entity1127 and occur predominantly in old age (73+/-12.8 years), more frequently in @entity1 (75%) than in @entity1 . The predilection site in the stomach is the corpus mucosa (64%) and they are often found in @entity1 suffering from @entity792 (36%). At the time of diagnosis, @entity652 measure 16.1+/-9.1 mm in size. In 30% of gastric pyloric @entity652 , transition to well-differentiated @entity420 has been noted. DISCUSSION: In our material, @entity652 is the third most common @entity1313 in the stomach. Since a search through the literature revealed only a few case reports on this lesion, it is possible that for some reason this lesion might be diagnosed more often than reported. CONCLUSION: Our study revealed that 30% of the gastric @entity652 showed continuous transition to well-differentiated @entity420 at the time of the initial diagnosis. This underscores the malignant potential of the lesion, and the need for polypectomy.
