CAA (Canine Acabthomatous Ameloblastoma) is a common tumor in dogs with 45.5% of situations affecting rostral mandible. This the case of a male dog, castrated, 10 yo with a large mandibular tumor with bone invasion as seen on CT scan. Curative intent surgery implies a bilateral rostral mandibulectomy. Clean margins after surgery, good cosmesis, good function and a cured old dog.
