ACHADOS PATOLÓGICOS DO LINFOMA MULTICÊNTRICO METASTÁTICO EM UM CÃO: RELATO DE CASO

Abstract

The neoplasms are considered one of the main cases in the medical and surgical clinic of companion animals, especially by the increase in life expectancy of these dogs. The lymphoma is one of the main malignant neoplasms diagnosed in dogs. The present work aims to report a case of a dog diagnosed with Metastic Multicentric Lymphoma, discussing the clinical and pathological findings. A dog, adult, no definite race with 7 years old was attended at the Veterinary Hospital o the Federal University of Paraíba (FUPB) campus II in the municipality of Areia, PB with a history of apathy, anorexia, progressive thinning and increase of lymph nodes. In clinical evaluation, it was observed generalized lymphadenopathy, increased body temperature (39,5 C ), hypocorous mucous membranes and increased abdominal volume. After abdominal utrasonographic evaluation, it was observed evident splenum and hepatomegaly and presence of reactive mesentric lymph nodes. After collection of complementary blood tests, an increase in hepatic enzymes, severe arregenerative normocytic anemia and leukocytosis due to lymphocytosis were indentified. In this way, was indicated a fine needle aspiration cytology of the lymphnodes, serology for Leishmaniasis aiming at differential diagnosis of lymphoid neoplasms and infections, as well as were collected fragments of reactive lymphnodes for histopathological evaluation, where high grade lymphoma was confirmed. Due to the advanced degree of the disease with presence of metastases, associeted with the great weakness of the animal and the low financial conditions of the tutor for a possible chemotherapy, the euthanasia was indicated and approved by the tutor. Thus, the animal was necropsied to evaluate the macroscopic aspects as well as collection of complementary tets.
