Cancer & Tumors

  • 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.

Canine 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.

  • Collecting tissue samples for cytology or histopathology allows 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. This handout outlines how these tests are used to help with diagnosis and treatment.

  • Ear canal tumors are abnormal growths that can develop from any part of the ear canal (the skin, the glands of the skin that produce earwax and oil, and the underlying connective tissues, muscles, and bones). Initially, these tumors may appear as one or more pink, white, or purple nodular masses in the ear canal. If benign, they may grow to a certain size and may or may not be problematic. If malignant, they may grow, ulcerate (break open) and bleed, and nearly always become infected, causing recurrent or chronic ear infections. The treatment of choice for ear canal tumors is surgical excision.

  • Elias Cancer Immunotherapy (ECI) is a personalized osteosarcoma (bone cancer) treatment for dogs. For this treatment, a vaccine is created from your dog’s tumor. After the vaccine is given, the dog’s body produces immune cells in response to the vaccine. These immune cells are harvested and made stronger, then re-injected to fight the osteosarcoma.

  • Esophageal tumors are extremely rare but more often than not malignant type tumors. The cause is unknown but cases in tropical environments may be due to infection by the worm Spirocerca lupi. Treatment options are limited as surgical complications are high due to the advanced nature of the disease at time of diagnosis.
