Ultrasonography andendoscopy showed gastric wall thickness. At necropsy, the gastric wall had significantthickening around the cardiac region, and metastases were found in some organs.Histologically, samples from the stomach wall and metastases showed the same tumor tissue.Immunohistochemistry was positive for epithelium markers. Ductal growth, keratinocytes orsignet ring cells were absent. The tumor was classified as an undifferentiated carcinomausing the World Health Organization’s (WHO) guide to international classification oftumors in domestic animals.
