Feline breast hyperplasia: Case report

Abstract

Feline mammary hyperplasia is a non-neoplastic condition, characterized by daily hypertrophy and hyperplasia or proliferation of the stroma and ductal epithelium of the mammary glands and usually affects young uncastrated cats. The most affected cats manifest enlarged, swollen, ulcerated breasts, in addition to other nonspecific signs. The diagnosis can be given through the history and clinical examination, but confirmed only with histopathological examination of the lesion. This study reports the case of an uncastrated cat, only 3 months old. It was attended with complaints of an increase in volume in the abdominal region about 3 weeks ago, with rapid growth 7 days ago. In this case, the clinical and historical aspect of the still very young patient, without having manifested his first estrus, were atypical. Thus, in addition to the fact that the imaging test was suspected, it was first suggested to be another pathology, which was discarded at the surgical moment, where the mass was removed by partial mastectomy, being confirmed the diagnosis of feline mammary hyperplasia at histopathological examination.
