Treatment includes simple removal of the tumor, radical mastoidectomy, and radiation therapy available or not. After consulting the literature, there have been 11 reports of such patients in the past. After 4 years of follow-up, 4 cases were found dead, 1 case died of other causes, and the others had only local erosion and no distant metastasis. This type of tumor grows slowly and only has a low degree of malignancy.
