Leiomyomas in Dogs and Cats
Leiomyomas are benign smooth-muscle tumors that can arise wherever smooth muscle exists, such as the uterus, stomach, intestine, and blood-vessel walls. Dogs are affected more often than cats. Surgical removal is the usual treatment, and follow-up care prevents spread.
Myomas (Rhabdomyomas and Leiomyomas) in Dogs and Cats
Myomas are muscle tumors that include rhabdomyomas and leiomyomas and may be benign or malignant. In dogs the malignant rhabdomyosarcoma is most often seen, with an unclear cause that may be hereditary. They can occur in any muscle-containing organ and are hard to remove once invasive.
Prostatic Tumors in Dogs and Cats
Prostatic tumors occur mainly in middle-aged and older dogs and mimic benign prostatic conditions. Adenocarcinoma is the most serious type and can spread to local lymph nodes, spine, and pelvis. Signs include weight loss, thirst, back pain, and difficulty urinating.
Vaginal and Vestibular Tumors in Dogs and Cats
Vaginal and vestibular tumors are the second most common reproductive tract tumor in female dogs and cats, ranging from benign leiomyomas to transmissible venereal tumors. Signs include a mass protruding from the vulva, difficulty urinating, and bloody or pus-like discharge. Surgical removal is the main treatment.
Uterine Tumors in Dogs and Cats
Uterine tumors are uncommon in dogs and cats, with leiomyomas being the most frequently seen type. They often produce no obvious signs and are found incidentally during abdominal palpation or ultrasound, though bleeding from the vulva can occur. Surgical removal of the uterus and ovaries is the treatment of choice.
