[Gastritis cystica profunda accompanied by multiple early gastric cancers].

Gastritis cystica profunda (GCP) is a rare disease which shows multiple cystic gastric glands within the submucosa of the stomach. GCP lesions mainly develop at the site of gastroenterostomy and exhibit benign behavior. However, there have been a number of debates over its malignant potential. Several reports have documented GCP accompanied by gastric carcinomas, but the relationship between the two conditions remains uncertain. Here we report two cases of GCP with dysplasia accompanied by synchronous multiple early gastric cancers without previous gastric surgery.
