Abstract:
Epithelial-myoepithelial carcinoma is rare, low-grade malignant neoplasm that compromises approximately 1% of all salivary gland neoplasms. We reported a 68-year-old woman with epithelial-myoepithelial carcinoma in the parotid gland. We analyzed demographic and clinicopathological characteristics of salivary gland epithelial-myoepithelial carcinoma which has been reported in 33 cases in Korea from 1992 to 2017, and compared this result to overseas retrospective cohort studies. There was no significance in terms of mean age at diagnosis, the predominance of females, low frequency in regional lymph nodes, and distant metastasis between the two groups. However, T classification and AJCC stage at diagnosis in domestic cases are more advanced than those of overseas cases. Although the recurrence rate in domestic cases has been reported lower than that of overseas, further study may be needed considering that the follow-up period after treatment is short in domestic cases.
