Oral melanomas are the most common form of oral malignancy with a relatively poor prognosis in dogs,and prone to older dogs.For older dogs,due to their low immune function,the treatment is more difficult,and traditional surgery is not effective in the treatment of oral melanoma in dogs.Therefore,it is extremely important to explore a novel treatment for oral melanoma in older dogs.In this case,a novel argon-helium cryoablation was used to treat type II oral melanoma in an elderly dog.The results showed that the tumor-like soft tissue was significantly reduced and the inflammatory secretions disappeared 20 days after surgery;the tumor-like soft tissue basically subsided and the wound healed well 3 months after surgery;and no tumor recurrence or metastasis occurred 9 months after surgery.It indicated that novel argonhelium cryoablation is safe and effective for the treatment of canine oral melanoma in older dogs,which is worth popularizing in veterinary clinic.
