LINFOMA INTESTINAL ALIMENTAR EM FELINO

Abstract

Lymphomas are neoplasms identified by the clonal proliferation of malignant lymphocytes. Also known as lymphosarcoma or malignant lymphoma, they originate mostly in lymphoid organs such as bone marrow, spleen and lymph nodes. However, they can occur in any tissue that has continuous migration of lymphocytes through various body tissues. This neoplasm can present different anatomical locations and thus classified as multicentric, mediastinal (or thymic), alimentary, cutaneous and extranodal. In felines, this identification extends to nasal, renal and nervous system lymphoma. The diagnosis of the disease can be made through histopathological and immunohistochemical examinations, requiring a biopsy of all layers of the intestine in three portions (duodenum, jejunum and ileum). The present work aims to present the clinical case of a feline with alimentary intestinal lymphoma and compare the findings and results with those present in the literature. In the present case, the diagnosis was made through biopsy, histopathological examination and immunohistochemistry. The main treatment is chemotherapy and drug therapy and the protocol used will depend on the degree of alimentary lymphoma. The patient was submitted to Lomustine every 21 days and showed improvement in the verified clinical signs.
