Gastric adenocarcinoma arising in gastritis cystica profunda presenting with selective loss of KCNE2 expression

Figure 1 Macroscopic finding and distribution of ectopic cystic lesion and cancer in surgically excised stomach. Surgically excised stomach (A) and schematic distribution of the lesions (B). Ectopic cystic mucosa is located mainly on the oral side and partly in the body part overlapped with a cancer lesion (shaded area). A well- to moderately-differentiated tubular adenocarcinoma in the intramucosal layer (checked area) and part of a poorly-differentiated component infiltrating the submucosal layer (blue area) are located mainly in the body part of the stomach.
