Plain-English summary
A 10-year-old male Scottish terrier was brought in for vomiting and occasional blood in his vomit. Over 14 months, the dog's condition worsened as a gastric polyp transformed into a more aggressive form of stomach cancer, leading to cancer spreading to the brain and spinal cord. Unfortunately, despite treatment efforts, the dog developed severe neurological issues and had to be euthanized. This case highlights that while gastric polyps in dogs are usually benign, they can sometimes become cancerous.

Abstract
Progressive carcinogenesis of a gastric polyp with transformation to gastric adenocarcinoma and subsequent development of leptomeningeal carcinomatosis is described in an adult male Scottish terrier. Presenting clinical signs consisted of vomiting with intermittent hematemesis. Surgical biopsies over the course of 14 months documented the progression from gastric polyp to minimally invasive gastric carcinoma to invasive gastric adenocarcinoma, a pathogenesis not previously documented in veterinary oncology. The patient ultimately developed neurologic pathology and was euthanized, and necropsy evaluation identified widespread carcinomatosis with accompanying leptomeningeal metastasis. As in humans, gastric polyps in dogs rarely have malignant potential.
