A case of feline fibroepithelial hyperplasia in a male cat

A nine-month old, orange tabby, intact male cat was brought to our clinic with the complaint of swelling in the mammary glands. In anamnesis; long acting progesterone was administered to the cat in a private clinic for suppression of oestrus one week ago. As a result of clinical examination, fibroepithelial hyperplasia was detected in all mammary glands. For the purpose of treatment, aglepristone started to be used for sequential five days. Because ulceration and necrosis occurred in the mammary glands at the end of the first week, the treatment was completed with total mastectomy section. In this article, a case of fibroepithelial mammary hyperplasia which was formed as a result of progesterone administration to suppress the oestrus in a male cat is described.
