초록
Epithelial-myoepithelial carcinoma is a very rare tumor. It is a low-grade malignant tumor and grows slowly, has a clear boundary of a lesion on a CT. As for its treatment, resection including free margin is the first priority, and it shows a recurrence rate of 40%, but its five-year survival rate is 87.5%. The authors lately carried out a micro-invasive examination of a mass in the right parotid gland of a 62-year-old female, but it neither showed any malignancy nor was distinguished from pleomorphic adenoma on CT. For the diagnosis and treatment, superficial parotidectomy was performed. In a histopathological examination, she was diagnosed with an epithelial-myoepithelia carcinoma so till now she does not show any recurrence. Therefore, the authors would like to report that epithelial-myoepithelial carcinoma of the parotid gland, which has rarely been reported in literature, was diagnosed and treated successfully.
