Abstract

Lymphoepithelial carcinoma is a rare but unique malignancy of the major salivary glands. The incidence of lymphoepithelial carcinoma is 0.4-1.4% of the major salivary malignant neoplasms. According to several serologic, immunohistochemical, and in situ hybridization studies, lymphoepithelial carcinoma is strongly associated with Ebstein-Barr virus infection. We present three cases of lymphoepithelial carcinoma associated Ebstein-Barr virus in the parotid gland, which was first presented with a painless and gradually enlarging infraauricular mass. We reoport on the clinical investigation, cytologic, histopathologic features and proper management. Along with a review of literature.
