Fibroadenomatous hyperplasia (FAH) is characterized by a rapid proliferation of mammary stroma and duct epithelium of 1 or more glands and predominantly affects younger female cats. Endogenous progesterone and exogenous progestogens play an important role in the genesis of FAH. The presence of progesterone receptors in fibroadenomatous tissue allows for targeted endocrine therapy with progesterone receptor blockers. We report on 22 young cats with FAH, none of which had responded to the withdrawal of progestogens or ovariectomy. The common signs were tachycardia (11 cats); skin ulceration, painful mammary glands, or both (16 cats); lethargy (8 cats); and anorexia (4 cats). The cats were treated with subcutaneous injections of the progesterone receptor blocker aglépristone on 1 (7 cats, 20 mg/kg) or 2 consecutive days (15 cats, 10 mg/kg/d) once weekly. All but 1 cat responded with a complete and lasting remission of signs after 1-4 weeks of treatment. Two cats had a short-term skin irritation at the site of the aglépristone injection. Two pregnant cats with FAH aborted after treatment with aglépristone and subsequently developed endometritis. In conclusion, the results of this study demonstrate that FAH in cats can be treated successfully with the progesterone receptor blocker aglépristone.

UI	MeSH Term	Description	Entries
D006965	Hyperplasia	An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	Hyperplasias
D007279	Injections, Subcutaneous	Forceful administration under the skin of liquid medication, nutrient, or other fluid through a hollow needle piercing the skin.	Subcutaneous Injections,Injection, Subcutaneous,Subcutaneous Injection
D010052	Ovariectomy	The surgical removal of one or both ovaries.	Castration, Female,Oophorectomy,Bilateral Ovariectomy,Bilateral Ovariectomies,Castrations, Female,Female Castration,Female Castrations,Oophorectomies,Ovariectomies,Ovariectomies, Bilateral,Ovariectomy, Bilateral
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011372	Progestins	Compounds that interact with PROGESTERONE RECEPTORS in target tissues to bring about the effects similar to those of PROGESTERONE. Primary actions of progestins, including natural and synthetic steroids, are on the UTERUS and the MAMMARY GLAND in preparation for and in maintenance of PREGNANCY.

D011980	Receptors, Progesterone	Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.

D002371	Cat Diseases	Diseases of the domestic cat (Felis catus or F. domesticus). This term does not include diseases of the so-called big cats such as CHEETAHS; LIONS; tigers, cougars, panthers, leopards, and other Felidae for which the heading CARNIVORA is used.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D004963	Estrenes	Unsaturated derivatives of the ESTRANES with methyl groups at carbon-13, with no carbon at carbon-10, and with no more than one carbon at carbon-17. They must contain one or more double bonds.	19-Norandrostenes,19 Norandrostenes
