Basal Cell Tumors in Dogs and Cats
Basal cell tumors are common, usually slow-growing skin tumors of dogs and cats that arise from the basal layer of the epidermis or hair follicles. Most are benign and stay confined to the skin, though larger ones can ulcerate. Complete surgical removal is typically curative.
Penile and Preputial Tumors in Dogs and Cats
Tumors of the penis and prepuce are uncommon and, when reported, have been seen only in dogs. Types include papilloma, transmissible venereal tumor, squamous cell carcinoma, fibroma, lymphosarcoma, and hemangioma. Growths may ulcerate, bleed, and produce a foul discharge.
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.
Sertoli Cell Tumors in Dogs and Cats
Sertoli cell tumors are hormone-producing testicular tumors of older male dogs and cats that cause feminization through excess estrogen. Signs include symmetrical hair loss, enlarged breasts, and a lengthened prepuce. Surgical removal of both testicles resolves most signs within a few months.
Testicular Tumors in Dogs and Cats
Testicular tumors are among the more common tumors in older dogs and are rare in cats. They often cause feminization from excess estrogen, including attraction from other males and symmetrical hair loss. Surgical removal of the affected testicle is the standard treatment, and neutering prevents the disease.
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.
Canine and Feline Ovarian Tumors
Ovarian tumors are uncommon in dogs and cats and usually arise as a primary growth, most often a granulosa cell tumor in older females. Hormone-secreting types cause persistent estrus, while others simply enlarge the abdomen; surgery is typically curative.
Canine and Feline Renal Adenoma and Kidney Tumors
Kidney tumors in dogs and cats may be primary growths such as renal adenoma or nephroblastoma, or spread from cancers elsewhere — metastatic kidney tumors are actually more common. Signs are vague but include weight loss, abdominal swelling, and changes in urination.
Canine and Feline Pancreatic Tumors
Pancreatic tumors occur in older dogs and cats and can be benign or malignant; many spread widely, especially to the liver. Insulin-secreting tumors cause low blood sugar, while surgical removal offers the best chance when caught early.
