A Pathological Study of Ovarian Abnormalities in Slaughtered NonPregnant Cows in Sulaimani Province.

Abstract

The current study was conducted to address the pathological conditions of ovaries of cows
 slaughtered at the abattoir in Sulaimani province, Kurdistan Region-Iraq. Among the 404
 genitalia samples collected from the non-pregnant animals, 206 (51%) were found without
 gross pathological abnormalities (with cyclic activity) and the remaining
 120(29.70%)samples were found with gross pathological abnormalities of ovaries. The
 ovaries exhibited the highest percentage of lesions 29.70%. Detected ovarian lesions
 included follicular cyst 10.89%, cystic corpus luteum 5.44%, mild ovariobursal adhesions
 4.45 %, sever ovariobursal adhesion 0.25%, paraovarian cysts 3.22%, ovarian hypoplasia
 1.98%, ovarian hemorrhage (hemorrhagic cystic corpus luteum) 1.48%, luteal cyst 1.24%,
 ovarian agenesis 0.50% and ovarian tumor (Gonadoblastoma) 0.25%. Histopathological
 examinations exhibited that the follicular cysts were lined by several layers of granulosa
 and theca cell, while the luteal cysts had follicular granulsa and the theca cells with marked
 luteinization of cytoplasm. Microscopically, the ovarian hypoplasia showed lack of
 ovarian follicles and oocytes, while the cavities of paraovarian cysts were lined by a single
 layer of cuboidal epithelial cells, and the hemorrhagic cyst showed scattered hemorrhagic
 spots close to the lumen and luteinized of granulosa and theca cells layers of cystic wall.
 Histopathologically, the ovarian gonadoblastoma (Dysgenentic gonadoma) was
 characterized by dual population of germ cell tumor and sex-cord stromal tumor and this
 observation has not been recorded in Iraq previously. It was concluded that ovarian
 abnormalities constitutes an percentage 0f 29.70%. And ovarian gonadoblastoma was
 firstly recorded in this study in Iraq.
