A 5-year-old spayed female Abyssinian cat had intermittent vomitting. Using gastrointestinal endoscopy, a massive lesion was found in the gastric mucosa. A diagnosis of Helicobacter infection was made, and gastric small B-cell lymphoma was diagnosed using cytopathology and histopathology of endoscopic samples. However, the samples were negative for lymphoid clonality. The cat was treated with Helicobacter eradication therapy for 30 days without any anticancer drugs. As a result, the symptoms resolved, and the lymphoma achieved complete remission. The recurrence of lymphoma in the gastric mucosa was not observed after one year of therapy, although a mild Helicobacter infection presisted.
