delmadinone and Hyperplasia

Three cases of fibroepithelial hyperplasia (FEH) of the mammary gland in the cat are reported. A one year old female cat had a distinct enlargement of the middle mammary glands, one on each side, 5 days after the first estrus. One week later the cat was treated with medroxyprogesterone acetate (Depo-Promone). The affected glands, along with the remaining glands, increased further in size. A five year old female cat was treated with Proligeston (Covinan) for the suppression of estrus. Two weeks later fibroepithelial hyperplasia occurred in two glands, one with a well demarcated ulceration. A seven months old male cat was treated with delmadinon acetate (Tarden) because of urine spraying. Two months later he had enlargement of all mammary glands. All three cats were treated with the progesterone antagonist Aglépristone (Alizine). Within 5 to 11 weeks the mammary glands had regressed to normal.
