Periglandular edema and epidermal necrolysis associated with the treatment of mammary hyperplasia in feline

Abstract

Feline mammary hyperplasia, also known as fibroepithelial hyperplasia is characterized microscopically by rapid growth of the stroma and ductal epithelium of the mammary glands in response to hormonal stimulation. The purpose of the present study was to report a case of breast hyperplasia in a feline, which had an unexpected progress by edema formation after ovarian-salpingo hysterectomy. A female, mixed breed cat, seven months old, nulliparous, was referred to the Department of Veterinary Medicine, Federal University of Sergipe, with historical of swelling of all mammary chains for a month, developing symptoms after administration of a contraceptive. As treatment, the realization of ovarian-salpingo hysterectomy was proposed to approach the edge because the breasts were very large. After two weeks, the breast tissue reduced, but large accumulation of liquid was noticed leading to the realization of radical mastectomy in the feline. This study draws attention in order to consider this type of edema after conservative treatment by ovarian-salpingo hysterectomy or drugs, as it can lead to a false interpretation of no reduction or even enlargement of the mammary tissue.
