Gastric metastasis from ovarian adenocarcinoma presenting as a subepithelial tumor and diagnosed by endoscopic ultrasound-guided tissue acquisition

Figure 1 Upper gastrointestinal endoscopy revealing a subepithelial tumor with intact overlying mucosa (black arrow) on the posterior wall of the gastric antrum.

Figure 2 Endoscopic ultrasonography showing a homogenous, hypoechoic mass within the muscularis propria (white arrows). Its echogenicity appears to be more hyperechoic than that of the muscle layer.
