Undifferentiated carcinoma of nasopharyngeal type (UCNT) is mainly known in its nasopharyngeal localization. Nevertheless, it can be found in other sites of the upper and lower aerodigestive pathways. The aim of this work is to study the characteristics and therapeutic management of UCNT located outside of nasopharynx; particularly at the larynx; in the light of the medical observation of a 65-years-old who presented a laryngeal lymphoepithelial carcinoma admitted to the department of otorhinolaryngology and head and neck surgery at the specialties hospital, Mohamed V university, Rabat-Morocco.
