MRI of the abdomen and pelvis with and without contrast of patient demonstrating evidence, a 0.6 x 1 cm focal polypoid-like mass lesion was observed near the junction of the distal body/antrum of the stomach.

MRI of the abdomen revealed a 1.6 x 1 cm focal polypoid-like mass lesion near the junction of the distal body/antrum of the stomach along the greater curvature with no extramural extension (Figure 1).
(a) H&E staining at 60x of signet cell gastric adenocarcinoma specimen obtained following total gastrectomy. Visualized are sheets of signet ring cells with eccentrically located hyperchromatic nuclei in the lamina propria in a background of acute gastritis with reactive epithelial changes of the surface epithelium. (b) Pancytokeratin staining at 60x after immunohistochemistry of the patient's biopsy specimen, which is consistent with the patient's diagnosis of signet ring cell adenocarcinoma.

Endoscopic biopsy of the mass demonstrated pathology consistent with signet ring cell adenocarcinoma (Figure 2).
