RESUMEN

Background: The postmortem examination offers the opportunity to study the processes involved in disease. Although a portion of veterinary medical professionals and students consider the necropsy as a diagnostic tool of purely academic interest, it can provide valuable assistance in formulating health strategies in order to prevent and control animal diseases. The number of necropsies performed in general is higher in universities where the cost is subsidized. In veterinary medicine, studies intended to assess the frequency of necropsy and the discrepancy between clinical and postmortem diagnosis of dogs are rare. The main purpose of the necropsy is to discover the cause of death of dogs, by defining a possible etiology and pathogenesis in order to reach a diagnosis. Material, Methods & Results: We used medical records and necropsy records to define the clinical and postmortem diagnosis, respectively. Data relating to deaths was recorded as the number of euthanized dogs and natural deaths in 2014. From the information cause of death, these were categorized as infectious disease, cardiac, gastrointestinal, renal, pulmonary, neurological, metabolic or endocrine disease, neoplastic disease, trauma, or systemic disease. We used the Binomial discrepancy in the comparison of the rates between different years and also to verify the association between discrepancy and the [...](AU)

RESUMEN

O linfoma é uma neoplasia que ocorre com frequência em gatos, porém seu diagnóstico tardio dificulta ou impossibilita o tratamento. Objetivou-se relatar o caso de um felino, 4 anos, apresentando prostração, anorexia, dispneia e dificuldade de deglutição e linfadenomegalia generalizada. À citologia notou-se células redondas, citoplasma escasso, núcleo basofílico com figuras de mitose aberrantes. Realizou-se teste imuno cromatográfico para Felv, o qual mostrou resultado positivo. No exame radiológico, foi observado aumento da densidade radiográfica nos pulmões e ausência de visualização de silhueta cardíaca. O animal veio a óbito e no exame necroscópico notou-se mucosas pálidas, linfonodos superficiais aumentados, coração recoberto por linfonodo mediastinal, linfonodos mesentéricos aumentados, e nos rins nódulos no parênquima.Exame histopatológico confirmou se tratar de linfoma.(AU)

Lymphoma is a cancer that occurs frequently in cats, but late diagnosis difficult or impossibletreatment. The objective was to report the case of a cat, 4 years, with depression, anorexia, dyspnea anddifficulty swallowing and generalized Iymphadenopathy. In the cytology was noted round cells, little cytoplasm,basophilic nucleus with aberrant mitotic figures. Immunochromatographic test was performed to Felv, whichshowed positive results. The x-ray examination showed an increase radiographic density in the lungs andwithout cardiac silhouette view. The animal died and necropsy examination showed pale mucous membranes,increased superficial lymphnodes, heart covered with mediastinal lymphnode, increased mesenteric lymphnodes, and kidneys nodules in the parenchyma. Histopathological examination confirmed the case oflymphoma.(AU)

El objetivo es presentar el caso de un gato, 4 anos, con prostacíon,anorexia, disnea y dificultad para tragar y linfadenopatía generalizada. En la citología se observó células redondas, poco citoplasma, núcleo basófilo con figuras mitóticas aberrantes. Prueba inmuno cromatográficase realizó para FeLV, que mostró resultados positivos. El examen radiológico, se observó un aumento de la densidad radiográfica en los pulmones sin vista de la silueta cardiaca.
