Vagina and Vulva - Pathology

PATHOLOGY OF THE VAGINA AND VULVA

• CONGENITAL DEFECTS

rectovaginal fistula or urethrorectovaginal fistula.

• TRAUMA

1. Prolapse: ewes in late pregnancy, or on oestrogenic pasture and in bitches, e.g. Boxer at oestrus.
2. Rupture: at parturition.

• VULVO-VAGINITIS

1. Mechanical: parturition.
2. Infective: cow infectious pustular vulvovaginitis, seen as hyperaemia and oedema with increased lymphoid nodules and ulceration.

• NEOPLASIA

Primary:

Squamous cell carcinoma: cow, ewe, mare, due to solar radiation.

Transmissible venereal tumour : in the bitch, transmitted at coitus by transfer of intact cells. Nodular, friable ulcerated lesion. Spontaneous regression. Uncommon where no free running dog population.

Leiomyomas/fibromas/lipomas: Melanotic tumours of the prepuce and vulva and sarcoids in equines.
