Osteomas in Dogs and Cats
Osteomas are common benign bone tumors formed from bone tissue, often linked to exostoses, injury, bone inflammation, or nutritional disorders. They usually cause no signs unless they press on a nerve or organ. Surgery is used when the site allows, and amputation for malignant limb tumors.
Mammary Tumors in Dogs and Cats
Mammary tumors are common in intact female dogs and are the third most common feline tumor. They often appear as firm nodules in the mammary chain and can ulcerate or spread to lymph nodes and lungs. Early spaying sharply lowers risk, and surgery is the main treatment.
Fibrosarcomas in Dogs and Cats
Fibrosarcoma is a malignant tumor of fibrous tissue and the second most common mouth tumor in dogs. About 60 percent arise in the skull bones and 30 percent in the long bones. It is firm, invasive, and bleeds easily when sampled. Surgery is the main treatment.
Melanomas in Dogs and Cats
Melanomas are pigmented tumors that may be benign or malignant, often in dark-skinned dogs such as Cocker Spaniels and Scottish Terriers. They favor the mouth, eyes, rectum, and perineum, with mucosal sites most at risk. Wide removal is used, but malignant forms carry a poor outlook.
Lipomas and Liposarcomas in Dogs and Cats
Lipomas are common, usually benign fatty tumors made of fat cells that grow slowly under the skin and rarely cause problems. Liposarcomas are the malignant form and can invade and break down. Solid lipomas are removed surgically, with weight control helping recovery.
Squamous Cell Carcinoma in Dogs and Cats
Squamous cell carcinoma is a skin tumor of the epidermal layer linked to long-term sun exposure and other skin irritation. It is the second most common skin tumor in cats and favors the head, ears, lips, and nose. Wide surgical removal is the main treatment, though it often recurs.
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.
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.
Optic Neuritis in Dogs and Cats
Optic neuritis is an inflammatory condition of the optic nerve that can cause sudden, often bilateral blindness in dogs and cats. The underlying cause is frequently unknown but may follow ocular trauma or infection, and prompt veterinary care is needed to protect vision.
