Mouth Cancer (Amelobastoma) in Dogs


Ameloblastoma in Dogs


Ameloblastoma, previously known as adamantinoma, is an uncommon neoplasm that affects the tooth structures in dogs. In most cases the mass is found to be benign in nature, but a rare, highly invasive malignant form is also recognized in some dogs. It may be present at any place within the dental arcade. As with many cancers, ameloblastoma mainly affects middle-aged or older dogs.


Symptoms and Types


Ameloblastoma is usually benign in nature and remains well localized. You may notice a firm and smooth mass covering the gingival space. The presence of a mass is usually enough to convince an owner to visit a veterinarian.




The exact cause is still unknown.




You will need to give a thorough history of your dog’s health and onset of symptoms. Your veterinarian will perform a thorough physical examination on your dog, with a detailed examination of the oral cavity, including the tumor mass. A complete blood profile will also be conducted, including a chemical blood profile, a complete blood count, and a urinalysis. In most cases the laboratory test results are within normal ranges and no abnormality related to this neoplasm is noticed. X-ray images of the skull will be helpful in estimating the penetration of the neoplasm within the bone structures. A computed tomography (CT) scan will give more refined results and will help in planning the treatment for your dog. Often a deep tissue biopsy will be conducted so that a sample of deeply penetrated neoplasm tissue can be examined. In this way your veterinarian can determine if the neoplasm is benign or malignant in nature.
