Initial misdiagnosis of gastritis cystica profunda: Two case reports

Figure 1 Gastroscopy in Case 1. A: Gastroscopy revealed a submucocal tumor situated on the greater curvature of the gastric fundus; B: Endoscopic ultrasonography indicated that the lesion was located within the submucosal layer (arrow). The internal echogenicity presented as a hypoechoic nodule containing multiple anechoic sacs; C: Endoscopic submucosal dissection was carried out on the lesion; E: The tissue specimen was obtained; F: Histopathological examination confirmed cystic expansion of the gastric glands and their infiltration into the submucosa.

Figure 2 Gastroscopy in Case 2. A: Gastroscopy revealed a pedunculated polypoid lesion located on the greater curvature of the gastric body; B: Endoscopic ultrasonography indicated that the solid-cystic lesion was positioned within the mucosal layer (arrow); C: Endoscopic mucosal resection was performed on the lesion, followed by an image of the resulting wound surface; D: The wound was closed using titanium clips; E: The tissue specimen was successfully obtained; F: Histopathological examination confirmed glandular hyperplasia and cystic dilatation in the deep gastric mucosa.
