Lymphoepithelial cell carcinoma of larynx masquerading as squamous cell carcinoma
Keywords:Lymphoepithelial carcinoma, Supraglottic larynx, Radiotherapy, Total laryngectomy, Epstein barr virus
Lymphoepithelial carcinoma is one of the common neoplasms seen to occur in nasopharyngeal subsite. Lymphoepithelial carcinoma (LEC) of the larynx is an uncommon entity; with 34 such cases reported in literature. Lymphoepithelial carcinoma (LEC) seems to behave in a fashion similar to nasopharyngeal carcinoma, except that most cases have not been associated with Epstein barr virus (EBV). We describe this patient with lymphoepithelial carcinoma (LEC) of supraglottic larynx who was treated with total laryngectomy and adjuvant radiotherapy and is on regular follow-up showed no evidence of local or distant metastasis.
