Tumors of Atypical Carcinoma of the Parotid Gland and Papillary Thyroid Carcinoma: A Case Report.

Lymphoepithelial carcinoma (LEC) is a variant of anaplastic carcinoma usually found in the nasopharynx. It is a rare, aggressive malignant tumor in the salivary glands, which is usually associated with Epstein-Barr virus (EBV), and often presents with facial nerve paralysis when in the parotid gland. This case report is unique in that our patient had EBV-negative LEC, with facial nerve involvement and a concurrent primary papillary thyroid carcinoma (PTC). We successfully managed this patient with surgery and adjuvant chemoradiotherapy. The patient has responded well to the treatment and she showed no evidence of disease at the 24-month follow-up.
