A leiomyoma is an uncommon benign tumor arising from smooth muscle in cats. They are seen most commonly in the gastrointestinal tract, however can be seen in association with the vagina and/or uterus.
There are no specific causes for leiomyomas, and they are seen most commonly in middle-aged to older dogs and cats. Dogs are more commonly affected than cats.
What to Watch For
Leiomyomas associated with the genital tract are most often found as incidental findings, and are on rare occasion associated with vaginal discharge.

Home Care and Prevention
It is very important to follow the instructions given to you by your veterinarian. If your pet has a recurrence of signs, contact your veterinarian at once. Prognosis varies depending on the location, size, and ability to remove the tumor surgically.
There is no known prevention of most leiomyomas. Ovariohysterectomy (spay) will prevent the formation of uterine leiomyomas.
