References in periodicals archive ?
MLEL involves only the major salivary glands, most often the parotid; about 15% of cases involve the submandibular gland.
MLEL tumors can be either infiltrative with indistinct borders, partially circumscribed, or multinodular.
Microscopically, the differential diagnosis of MLEL includes benign lymphoepithelial lesion, metastatic undifferentiated carcinoma (especially of the nasopharynx), anaplastic carcinoma, poorly differentiated squamous cell carcinoma, and malignant lymphoma.
