Ectopic pregnancy is an abnormal embryonic/fetal location. In animals this pathology occurs mostly as an extrauterine abdominal pregnancy. This paper describes a case of an abdominal pregnancy in a cat. Initially, two live fetuses were diagnosed. One month later, explorative laparotomy revealed dead encapsulated, underdeveloped fetuses in the peritoneal cavity. The uterus seemed intact. Histological examination of eight longitudinal and transverse uterine samples did not reveal connective tissue as a remnant of the scar. However, this finding does not exclude the possibility of a previous uterine rupture, since uterine tissues may have regenerated without a visible trace of an earlier trauma.
Mammary fibroepithelial hyperplasia (fibroadenoma) is a non-malignant lesion of the mammary gland, occurring in young female felines as a result of overproduction of progesterone or the use of gestagens. This disease is characterized by an increase in the size of several or all mammary glands which are enlarged and accompanied by pain, often with mastitis. In three cases of feline fibroepithelial mammary gland hyperplasia (two spontaneous and one after depo-gestagens treatment) antigestagen (alepristone) was used. The results obtained suggest that progesterone receptor blockers should be the first active drug treatment for cats with fibroadenomatosis because this encourages speedy remission of lesions and does not influence the cats’ fertility as was the case with previous therapy methods.
