Uterine disorders in 59 rabbits.

The medical records of 59 rabbits with uterine disorders were assessed retrospectively. Ten animals were presented because of vaginal discharge; the reasons for presentation of the remaining 49 rabbits included mammary masses, skin tumours, anorexia and poor general health. All the rabbits underwent a clinical examination, and 54 were examined by ultrasonography and/or radiography. Forty-five rabbits underwent ovariohysterectomy and the other 14 rabbits were euthanased, three because of pulmonary metastases and 11 because of very poor health unrelated to their uterine disease. The genital tracts of all the rabbits were submitted for histological examination. Endometrial hyperplasia (in 24 rabbits) and adenocarcinoma (in 18 rabbits) were the most common uterine disorders; in a further 11 cases both conditions were observed. The remaining six rabbits had other uterine disorders. Four rabbits that were presented with adenocarcinoma of the mammary gland were found to have concurrent uterine disorders. The mean age of the rabbits with endometrial hyperplasia was 4.5 years, and that of the rabbits with adenocarcinoma was 6.1 years. Four rabbits had ovarian tumours.
