MASTECTOMIA UNILATERAL COM LINFANDENECTOMIA AXILAR EM CADELA: RELATO DE CASO

Abstract

Mammary neoplasms are characterized by abnormal cell growth within mammary tissue and are frequently observed in female dogs and cats. This condition represents a multifactorial occurrence associated with age, breed, hormonal factors, and contraceptive use. Diagnosis involves assessing the clinical history, physical examination, cytology, biopsy, and imaging tests such as ultrasound and radiography. Treatment via mastectomy varies depending on tumor location and size. This study describes the case of an 8-year-old mixed-breed female dog, weighing 15.3 kg, diagnosed with benign mixed mammary tumor and cystic ductal hyperplasia with tissue fibrosis, attended to in Teófilo Otoni-MG in June 2023. The chosen treatment involved unilateral mastectomy with axillary lymphadenectomy in the left mammary chain. Imaging tests did not detect metastases. Following unilateral mastectomy with axillary lymphadenectomy and ovariohysterectomy, the patient experienced a smooth post-surgical recovery without complications. Histopathological analyses indicated a benign mammary tumor and lymph node hyperplasia.
