Plain-English summary
A 12-year-old male Jack Russell Terrier was brought to the vet because he was vomiting intermittently. An ultrasound showed a thickened stomach wall and a mass, which was later confirmed to be a gastric plasmacytoma, a type of tumor in the stomach. The mass was about 2.1 cm in size and was found between the stomach layers. After diagnosis, the vet recommended treatment options, which may include surgery or other therapies to manage the tumor. The outcome for this dog will depend on the chosen treatment plan and how well he responds.

Abstract
A 12-year-old castrated male Jack Russell Terrier presented with intermittent vomiting. Abdominal ultrasonographic examination detected a thickened stomach wall with a mass measuring approximately 1.5 cm in diameter. Computed tomography revealed a solitary mass measuring approximately 2.1 cm in diameter between the submucosa and muscle layers in the greater curvature the pyloric region of the stomach, and a swelling in the hepatic lymph node. The gastric mass was composed of round neoplastic cells arranged in a diffuse pattern. The neoplastic cells had a round nucleus and a pale abundant cytoplasm. Multinucleated giant cells were often found. Hyalinized eosinophilic material, which did not stain with Congo red and had no affinity for thioflavin T, was also observed. Neoplastic cells were immunopositive for MUM1, CD79a and Ig lambda light chain but negative for CD3, CD20, BLA36, IgG and Ig kappa light chain. Stromal eosinophilic material was positive for Ig lambda light chain. The neoplasm was therefore diagnosed as a gastric plasmacytoma with non-amyloid Ig lambda light chain deposition.
