title: Acanthomatous ameloblastoma of the maxilla of an adult alpaca.
abstract: An adult alpaca presented with a large maxillary swelling. Facial trauma or a tooth root abscess was suspected. Radiographically there was a large expansile lesion displacing the right maxillary teeth. An ameloblastoma was diagnosed histologically and palliative radiation therapy was attempted. Because of poor response to therapy and anorexia the animal was euthanized. Necropsy findings confirmed an ameloblastoma of acanthomatous type.
