Cervical leiomyoma in a dairy cow during pregnancy.

In the present report we describe a case of cervical leiomyoma that was diagnosed at parturition in a Holstein cow. The tumor mass, which measured 25.5 cm x 21.5 cm x 14.5 cm in size and weighed 4.5 kg, was removed surgically. The tumor was solid, well circumscribed, whitish-pink colored, and encapsulated. The tumor was diagnosed as leiomyoma. The leiomyoma had no adverse effects on pregnancy. This is the first report of a bovine cervical leiomyoma during parturition.

True vaginal prolapse in a bitch.

Frequently, vaginal fold prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during proestrus and estrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In the bitch, this type of true vaginal prolapse is a very rare condition. This short communication describes a 5-year-old female, cross-breed dog in moderate condition, weighing 33 kg, with distocia and true vaginal prolapse. Abdominal palpation and transabdominal ultrasonography revealed live and dead foetuses in the uterine horns. One dead and four live fetuses were removed from uterus by cesarean section. The ovariohysterectomy was performed after repositioning the vaginal wall with a combination of traction from within the abdomen and external manipulation through the vulva. Re-occurrence of a vaginal prolapse was not observed and the bitch recovered completely after the surgical therapy. Compared to other vaginal disorders, vaginal prolapse is an uncommon condition in the bitch. In the present case, extreme tenesmus arising from distocia may have predisposed to the vaginal prolapse. The cause of dystocia was probably the disposition of the first foetus. We concluded that the vaginal prolapse was the result of dystocia in the present case.
