FIBROEPITHELIAL HYPERPLASIA OF THE MAMMAR Y-GLAND WITH SPONTANEOUS REGRESSION IN A CAT

Clinical course, ultra-sonographic features, macroscopical and histopa thological findings of one case of fibroepithelial hyperplasia of the mammary gland in a 6 month old female cat are described. This case sho ws two distinctive features: firstly, based on the case history we sup pose that the lesion is not dependent on progesterone and secondly, a regression of several swellings spontaneously occurred without therape utic intervention. Analysing the pedigrees of 12 cats with fibroepithe lial hyperplasia bred at the Central Animal Facility, Medical School H annover, evidenced a potential hereditary predisposition to this disea se (retrospective study).
