A spayed Samoyed bitch, 12 years old, was presented to the Veterinary Clinical Hospital of the University of Cordoba (Spain) with abundant vulvar sanguineous discharge over the previous three days. The clinical examination revealed a remarkable vulvar mass, which protruded through the vulvar lips. Abdominal ultrasonography revealed the presence of structures compatible with uterus and ovary, which had been presumably removed eight years previously. An exploratory laparotomy was carried out, which confirmed the presence of the right ovary and a remnant of the uterus. The histological evaluation confirmed a granulosa cell tumour in the ovary, and an enlarged portion of the right uterine horn with brownish contents. The vulvar mass was also surgically removed and fibroma with some fibrosarcoma areas was diagnosed. This case shows the evolution of ovary and uterus into the abdomen, which were incorrectly removed after ovariohysterectomy eight years previously.
