[A malignant salivary lymphoepithelial lesion with a poorly differentiated epidermoid carcinoma. Apropos a case].
A case of malignant lymphoepithelial lesion of the submandibular gland is reported in a 71-years-old woman. The carcinoma showed a poorly differentiated pattern and its epidermoid nature was obvious after immunohistochemistry and electron microscopy. The epithelial nests were lying in an abundant lymphoid stroma consisting of small lymphocytes. A recurrence occurred ten months after surgical treatment. This observation is compared with those already related in the literature.
