Abstract

Neoplasmas of the mammary gland are considered one of the leading causes of death in dogs and cats. The increase in incidence is due to increasing life expectancy of these animals in recent years. Due the neoplasmas be one of the most frequent problems encountered in veterinary medical clinic and by the lack of data on the occurrence of these diseases in the South West of Paraná, the objective of this study was to evaluate the clinical and epidemiological aspects of disease, of the neoplasmas of the mammary gland in cats and dogs in the municipality of Realeza - PR. For realization of this work were analyzed samples of neoplasmas of the mammary gland and oncological records of cats and dogs attended in Veterinary Hospital University, Federal University of Fronteira Sul, in the period April 2014 to May 2015. The animals seen were separated into groups according to the breed, species, age and sex and when possible was heals, fine needle aspiration citology (FNAC) of tumors. The fragments of the neoplasmas were from surgical removals and necropsies performed in the period covered by the study, on the basis of these histological examinations have been carried out for the identification and classification of tumors, according to the classification described by Cassali et al., 2011. From the results, it was found that aspiration biopsy is an important tool for the diagnosis of the neoplasmas. Mammary gland tumors have a higher incidence in dogs than in cats; the age of higher occurrence was between 7 and 10 years; animals without breed set were the most affected and the neoplasmas of higher occurrence were the malignant, being the most common complex carcinoma.
