Amyloid-producing Odontogenic Tumor in the Maxilla of Two Dogs

Abstract

Two Shih-Tzu dogs were diagnosed as amyloid-producing odontogenic tumor in the maxilla. We concluded the surgical excision difficult, because of their anatomical location. So we treated them with radiotherapy and surgical reduction, but the size of the tumors increased, and caused a decline of quality-of-life. Each of them died after 12 and 16 months from the first medical examination. Amyloid-producing odontogenic tumor is classified as a benign tumor, but its local infiltration is extreme, and showed an aggressive behavior.
