Ovarian Teratoma in a dog
This is from a 3 years old female dog that had a pyometra. During surgery I have noticed that the left ovary was increased in size (about the size of a golf ball). The histoathology results showed an ovarian teratoma, and multiple cystic corpora lutea.. The tumor included neuronal tissue, keratinized cells and ciliary cells. This is a benign tumor that is often found in young females.
