Plain-English summary
A 5-year-old mixed-breed female dog was found to have a cyst and a whitish mass in her ovaries during surgery, even though she had previously undergone spaying. The vet removed both the cyst and the mass along with her uterus. After examining the tissue, the vet diagnosed the mass as a rare type of tumor called a teratoma, which can contain different types of tissue. Fortunately, the surgery was successful, and the dog was treated for her condition.

Abstract
An exploratory laparotomy on a mixed-breed bitch of an estimated age of 5 years revealed that she had undergone ovariectomy in the past, but a cystic structure was present in the area of the right ovary and a whitish mass, approximately 3 cm in diameter, in the area of the left ovary. These structures were removed together with an apparently normal uterus. Histological examination of the cyst showed a thin layer of connective tissue, while the left ovarian mass revealed ovarian tissue and highly differentiated nervous tissue, confirmed through immunohistochemistry. A presumptive diagnosis of mature ovarian teratoma was made. Although teratomas generally contain recognizable elements from more than one of the three germ cell layers, they can also be monophasic, when there is only one germ layer component. Ovarian teratomas are rare in the dog and never before have been reported in an ovarian fragment.
