Lymphoepithelial carcinoma versus large cell undifferentiated carcinoma of the major salivary glands

Abstract

The clinicopathologic features of LEC and LCUC of the major salivary glands were different. LEC was associated with EBV, and patients with LEC had a much better prognosis compared with the prognosis for patients with LCUC. Therefore, LEC should be put in an independent group and should not be included in the same category as undifferentiated carcinomas of the salivary gland.
