Management of Lymphoepithelial Carcinoma of the Parotid Gland with Liver Metastasis: A Case Report

Abstract

Objective: Lymphoepithelial carcinoma (LEC) is rarely found as one type of salivary gland malignancy, especially the parotid gland. Based on data only covers 0.86% of all cases of salivary gland malignancies with an annual incidence rate of 0.01 cases per 100,000 population. Liver metastasis from this type of cancer is very uncommon.
Methode: We reported a 64-year-old female patient who presented with a lump in the left neck which enlarged within four years. Total parotidectomy and modified radical neck dissection were done and the diagnosis of lymphoepithelial carcinoma of the parotid gland was establishes based on pathology examination. The patient was then given adjuvant radiotherapy. Five months after initial treatment, the patient shows no locoregional recurrence. However, the patient developed multifocal liver metastases which were deemed inoperable.
Results: Liver metastases in the case of lymphoepithelial carcinoma have a worse prognosis than other types of cancer because it usually manifests in multiple and disseminated lesions rather than solitary.
