LEC of the left sublingual gland in a 44-year-old woman with a painful mass in the mouth for 8 years. Axial T2-weighted imaging (A) shows a homogeneous slightly hypointensity mass with a partially defined margin in the left sublingual gland (arrow). Axial gadolinium-enhanced T1-weighted image (B) shows the mass with homogeneous moderate enhancement (arrow). Histopathologic examination (C) shows nests of neoplastic epithelial cells separated by abundant lymphoid stroma (hematoxylin-eosin, original magnification × 100). In situ hybridization by using a digoxigenin-labeled EBER probe (D) shows the nuclei of the malignant epithelial cells strongly positive but negative in the surrounding lymphocytes (original magnification × 100).
