Plain-English summary
A 10-year-old female mixed-breed dog was brought in for vomiting and not wanting to eat for the past seven months. After examining her abdomen and performing tests, the vet found a mass in her stomach and diagnosed her with a rare type of cancer called intravascular lymphoma. The owner chose not to pursue chemotherapy, so the dog was given a steroid called prednisolone to help manage her symptoms. Unfortunately, two months later, she developed a large stomach ulcer and was euthanized four months after her initial visit.

Abstract
Intravascular lymphoma (IVL) is a rare, high-grade, extranodal lymphoma characterized by selective proliferation of neoplastic lymphocytes within the lumen of small vessels. A 10 yr old female intact mixed-breed dog was presented with a 7 mo history of vomiting and anorexia. Physical examination revealed abdominal discomfort. Ultrasonography and endoscopy identified a submucosal gastric mass. Excision was performed by partial gastrectomy and histopathology and immunohistochemistry confirmed a T-cell IVL. The owner declined chemotherapy, and the dog was instead treated palliatively with prednisolone. Two months after surgery, vomiting recurred and abdominal ultrasonography revealed a large gastric ulcer with focal peritonitis. The dog was euthanized 4 mo after initial presentation and postmortem examination confirmed IVL recurrence in the stomach and an isolated nodule of neoplastic cells in the omentum. No involvement of other organs was found following histopathological examination. This is the first description of primary gastric intravascular lymphoma causing chronic vomiting in a dog.
