Background: Lymphoepithelioma (Squamous cell carcinoma with associated lymphoid stroma) commonly occurs in nasopharynx.
It occurs rarely at other sites like oropharynx, laryngo-hypopharynx and salivary glands. Lymphoepitheliomas of base of
tongue are less than 1% in head and neck region.
Case Report: We present a rare case of 65years old male patient with lymphoepithelioma of base of tongue with bilateral cervical
level II lymph nodes and immunohistochemistry showing positivity for cytokeratin and negativity for leucocyte common antigen.
Patient is also a known Hansenís disease, which was treated 10 years back and has left lower limb amputated for chronic
Treatment Guidelines: Treatment course was planned as per stage with radical radiotherapy with concurrent chemotherapy.
Wider volume (CTV) was given to cover distant regional spread as the tumour is locally aggressive.
Conclusion: Lymphoepitheliomas are radiosensitive tumours with higher rates of locoregional tumour control, achieved with
concomitant chemo radiotherapy in all head and neck sites.Distant metastasis was seen in patients with lymph node involvement
and was a cause of poor prognosis. Non nasopharyngeal lymphoepithelioma can be planned better than nasopharyngeal
tumours as in the later, organs at risk are near by.
