Lymphosarcoma in dog attended at the Veterinary Hospital of Anhanguera – Brazil: Case report

Abstract

Lymphomas (lymphomas or lymphosarcomas) are a large group of neoplasias that have their origin in common, lymphoreticular cells, and arise due to an uncontrolled clonal proliferation of this type of cells. In canids, lymphoma accounts for approximately 18% of all malignancies and 80% of hematopoietic tumors. The diagnosis of lymphoma is performed by fine needle aspiration for cytological evaluation of the respective lymph node, mass or organ affected and must include a complete physical examination, hematological and biochemical profile, urinalysis, abdominal radiography and/or ultrasonography and chest X-ray. After established diagnosis, staging of the lymphoma should be determined. Systemic chemotherapy continues to be the treatment of choice for canine lymphoma and the combination of several protocols has a greater efficacy compared to the use of only one chemotherapeutic. The aim of this work is a case report of a dog of four years of age with histological diagnosis of lymphosarcoma.
