Ultrasonographic and histopathological findings of gastric adenocarcinoma in a uremic cat

Abstract

Gastric carcinoma is very rare in cats. In this case report, a gastric adenocarcinoma in a chronically uremic cat is described. The cat presented with vomiting, dysorexia and weight loss. The ultrasound examination demonstrated an ultrasonographic pseudolayering effect on the gastric wall, which is suggested as a specific sign of adenocarcinoma. On histopathology, this adenocarcinoma was organized, and a continuous intralymphatic infiltration line was visible underneath the muscularis mucosae, which might explain the pseudolayering effect.
