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 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.
Canine and Feline Gastrointestinal Carcinoma
Gastrointestinal carcinoma is an uncommon but serious gut cancer in dogs and cats; when it arises in the stomach it thickens the wall and leads to ulcers and infection. Early surgical removal offers the best chance, while advanced cases — especially rectal — carry a poor outlook.
Canine and Feline Metastatic Lung Tumor
Metastatic lung tumors are cancers that have spread to the lungs from a primary tumor elsewhere, such as mammary, bone, or oral melanoma. Signs resemble primary lung disease but cough is less common, and the outlook is generally poor.
Canine and Feline Primary Lung Tumor
A primary lung tumor arises in the lung tissue itself and is seen mainly in older dogs and cats, with signs much like pneumonia — cough, weight loss, and poor appetite. Surgical removal of the affected lobe is the preferred treatment, though long-term outlook is limited.
Canine and Feline External Ear Canal Tumors
Tumors of the external ear canal arise from the canal's lining or glands and can congest and block the passage, causing discomfort and discharge. Surgical removal of the affected canal usually gives a good outcome.
