Chondrosarcomas arise from cartilage, which is a connective tissue primarily found where bones meet with joints, as well as at other locations in the body such as the nasal cavity, and ribs. Chondrosarcoma is a rare tumor in cats, but it can occur. Clinical signs of chondrosarcoma may vary significantly, depending on where the tumor arises. Although the mass may grow rapidly, less than 20% of feline chondrosarcoma cases metastasize to other parts of the body. Therefore, surgical removal is curative in many cases.

Chondrosarcomas arise from cartilage, which is a connective tissue primarily found where bones meet with joints, as well as at other locations in the body such as the nasal cavity, and ribs. Chondrosarcoma is the second-most common primary bone tumor in dogs. Canine chondrosarcoma most commonly affects the flat bones of the body, such as the ribs, skull, nasal cavity, and pelvis, although the limbs can also be affected. Aggressive surgical removal is typically recommended, although radiation therapy may also be used, depending on location of tumor. Metastasis may occur but is relatively uncommon.

Cornifying epitheliomas are benign skin tumors that are secondary to keratin buildup. They can develop anywhere but may be most troubling if they affect the skin around the nail, causing swelling, discomfort, and lameness. Surgical removal is curative in most cases.

A cutaneous histiocytoma is a common benign (harmless) tumor of the skin in dogs, typically younger ones. Their development, appearance, diagnosis, and treatment are explained in this handout.

Cutaneous histiocytosis is an uncommon condition in dogs. It is a non-cancerous increase in the number of reactive cells (histiocytes) caused by an immune system dysfunction. It generally manifests as multiple bumps and nodules confined to the dog's skin. The clinical signs, diagnosis, and treatment of this condition are explained in this handout.

Lymphoma is a type of cancer that is common in cats. When it occurs in the skin, it is called cutaneous lymphoma, but this form is quite rare. Feline cutaneous lymphoma can present various clinical signs, including itching, alopecia (hair loss), scaly skin, skin redness, loss of skin color, ulcers, nodules, pustules, and plaques.

Cutaneous papillomatosis is the development of papillomas (non-cancerous growths, or warts) caused by the papillomavirus and affects many pet birds. Commonly affected species are finches, canaries, cockatiels, budgerigars, and African grey parrots. The clinical signs and treatment for this condition are explained in this handout.

Collecting tissue samples for cytology or histopathology allow a pathologist to often give a diagnosis of the type of mass or tumor your pet has. Samples can be obtained by fine needle aspirate or biopsy, where a piece of the mass is cut out. Based on what the mass appears like under the microscope, the pathologist can often give a prognosis of how the tumor will behave.

Common conditions of pet ferrets include diarrhea, intestinal foreign bodies, parasites, heart disease, and various tumors. This handout outlines the causes, clinical signs, and treatment options for each of these conditions. Any variation from normal should be a cause for concern and should be immediately evaluated by your veterinarian.
