Avaliação clínica, reprodutiva e histopatológica de neoplasias mamárias em cadelas atendidas no hospital universitário veterinário (HUV) da UFPB em 2024

Abstract

Mammary neoplasms consist of the abnormal and disordered growth of mammary tissue cells, which can lead to benign or malignant tumors. In female dogs, these tumors represent an important challenge in veterinary public health, given their high incidence and clinical complexity. The aim of this study was to evaluate the clinical, reproductive and histopathological aspects of female dogs diagnosed with mammary neoplasms treated at the Veterinary University Hospital (HUV) of the Federal University of Paraíba (UFPB). The study was conducted by means of a retrospective analysis of clinical care reports and anatomopathological reports of 51 female canine

patients diagnosed with mammary neoplasia. The majority of the patients were non- breed females (60.78%) and not neutered, with an average age of nine years. The

data revealed that most of the bitches had reproductive comorbidities associated with mammary and/or ovarian tumors, with ovarian alterations observed in 55.17% of the cases evaluated and uterine alterations in 70.37%, especially granulosa cell tumors and cystic endometrial hyperplasia, respectively. The findings reinforce the importance of early elective castration as an effective preventative measure against mammary neoplasms and reproductive alterations, as well as the need for a comprehensive clinical and anatomopathological approach for the diagnosis and proper prognosis of patients.Keywords: mammary neoplasia; bitches; reproductive disorders; ovary; uterus; castration.
