Radiation therapy for amyloid-producing odontogenic tumor in a cat: a case report.

Amyloid-producing odontogenic tumor (APOT) is a rare odontogenic neoplasm in cats, characterized by amyloid deposition within the tumor. Surgical resection is commonly recommended, but in cases where complete excision is difficult, radiation therapy may be considered as an alternative treatment. In this case report, a 10-year-old male neutered domestic cat with an APOT of the maxilla was treated with radiation therapy and showed favorable outcomes. The treatment protocol involved a total dose of 42 Gy (Gray) administered over six sessions, with good tumor control, and minimal side effects observed over a 481-day follow-up period. This case suggests that radiation therapy can be an effective treatment option for APOT, particularly in cases where surgical excision is not feasible.
