Plain-English summary
A 10-year-old male neutered domestic cat was diagnosed with a rare tumor in his upper jaw called an amyloid-producing odontogenic tumor (APOT). Since surgery was difficult, the veterinarian recommended radiation therapy instead. The cat received a total of 42 Gy of radiation over six sessions, which effectively controlled the tumor with minimal side effects. After 481 days of follow-up, the cat showed good results, suggesting that radiation therapy can be a helpful option when surgery isn't possible.

Abstract
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.
