Computed tomography (CT) images combined with fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET/CT). (A) CT revealed a 29x24 mm mass in the gastric antrum (arrows) with perigastric and paraaortic lymph node swelling (arrow heads). (B) FDG-PET/CT showed intense FDG uptake in the corresponding mass and swellings.

Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) combined with CT (18F-FDG PET/CT) showed intense FDG uptake in the gastric mass, perigastric lymph nodes, paraaortic lymph nodes, and left supraclavicular lymph nodes (Fig. 1).
Upper gastrointestinal endoscopy revealed a submucosal tumor covered with smooth mucosa in the gastric antrum.

Upper gastrointestinal endoscopy revealed a submucosal tumor covered with normal gastric mucosa (Fig. 2).
Light microscopy of gastric biopsy and ovarian tumor specimens. (A) Gastric biopsy revealed an adenocarcinoma with papillary and micropapillary growth patterns (Hematoxylin and Eosin (H&E) staining, original magnification x20). With higher magnification, the tumor cells showed high nuclear grades with high nuclear/cytoplasmic ratios (inset, H&E staining, original magnification x40). (B) Histology of the previous ovarian tumor showed a similar growth pattern to that of the gastric tumor (H&E staining, original magnification x20, inset x40).

She underwent gastric boring biopsy, the specimen from which revealed a poorly differentiated adenocarcinoma with a micropapillary component (Fig. 3A). The tumor was confirmed as a metastatic serous adenocarcinoma from the ovary (Fig. 3B).
