A four-year old, 26.5 kg, Boxer bitch was presented to the Department of Reproduction in the Clinic of Dogs and Cats with a six month history of vulvar swelling and vaginal discharge. General gynaecological examination showed an extremely swollen, oedematous and tough-elastic highly irritable vulva. A vaginal smear revealed the presence of superficial cells and red blood cells. After repeated unsuccesful administrations of HCG and GnRH the owner of the bitch agreed to surgical treatment. An ovariohysterectomy was performed and on the left ovary a grapefruit-size structure was found. Three nodular structures were found retroperitoneally and were also dissected. Histological examination showed a disgerminoma in metastasises, mitotically active with a bad prognosis. However, at a check up twenty months subsequently the patient was still alive.
