LARGE CELL INTESTINAL LYMPHOMA IN A CAT - CASE REPORT (Atena Editora)

Abstract

Lymphomas or lymphosarcomas are neoplastic diseases that affect a large number of domestic felines, classified into four categories and, among these, food lymphoma stands out, found in 70% of cats, affecting mainly the intestine, in second place the stomach and, to a lesser extent, the mesenteric lymph nodes of the animal. Histologically they are divided into: low grade; intermediate grade or high grade and large granular lymphocytes, the latter more aggressive, rapid course, little or no remission, even with the adoption of a chemotherapy protocol. Life expectancy is short and clinical signs are non-specific, confusing them with inflammatory bowel diseases, which contributes to the rapid advancement of neoplasia without the adoption of adequate treatment. This paper presents, initially, a brief bibliographical review on lymphomas or lymphosarcomas in domestic felines and, in the sequence, addresses a clinical case report of alimentary lymphoma of large cells of the type large granular lymphocytes in a male feline, mixed breed, castrated, 13 years old, positive for feline immunodeficiency (FIV), with a history of inappetence, frequent vomiting of semi-digested food mixed with hairballs, diarrhea and discomfort on abdominal palpation. The aim of this work is to alert veterinarians about the occurrence of this type of neoplasm, which is highly aggressive and has a rapid course, with nonspecific clinical signs and a wide differential diagnosis for several diseases of the intestinal tract.
