Plain-English summary
An 11-year-old Siberian Husky, an 8-year-old mixed breed, and a 5-year-old Border Collie were all diagnosed with rare growths in their nasal passages called respiratory epithelial adenomatoid hamartomas. The Husky received radiation therapy but had limited follow-up. The mixed breed showed a good response to a different radiation treatment and lived for 26 months after, while the Border Collie had stable disease for 18 months with ongoing treatment. These cases suggest that radiation therapy can be effective for these types of nasal tumors in dogs, potentially leading to longer survival.

Abstract
Intranasal respiratory epithelial adenomatoid hamartomas (REAHs) and chondro-osseous respiratory epithelial adenomatoid hamartomas (COREAHs) are rare in dogs. Affected dogs are often treated surgically but published outcomes data are scant. Here, 3 cases are described. An 11-year-old Siberian Husky with advanced REAH underwent stereotactic radiosurgery (17 Gy); had no acute radiotoxicity and experienced short-lived clinical improvement before loss to follow-up. An 8-year-old mixed breed dog with advanced COREAH causing cribriform lysis received stereotactic body radiotherapy (SBRT) (30 Gy in 3 fractions); had no acute radiotoxicity, a strong partial response to treatment, and was euthanized 26 months after irradiation. A 5-year-old Border Collie with sinonasal COREAH and cribriform lysis was treated with 3D conformal radiotherapy (45 Gy in 12 fractions); the dog had stable disease for 18 months with ongoing follow up at the time of publication. These experiences provide evidence that REAH/COREAH could be radioresponsive with potential for prolonged survival.
