Intraoperative Frozen Section Biopsy for the Auxiliary Diagnosis of Transmural Intestinal Intermediate T-Cell Canine Lymphoma.

Intestinal lymphoma is characterized by a malignant lymphoid neoplasm with multifactorial causes, variable clinical symptoms, and, in some cases, rapid progression. This article describes a case of intestinal lymphoma in a dog that had a history of diarrhea lasting two months, accompanied by episodes of hematochezia, which was treated using the CHOP 19 protocol. A seven-year-old male Golden Retriever presented to a veterinary clinic with clinical signs of diarrhea, prostration, and the presence of bloody feces, as reported by the owner.
