Epithelial-myoepithelial carcinoma of the base of tongue: Pathology and management

Epithelial-myoepithelial carcinoma is a rare tumor which makes up about 0.2% of epithelial neoplasms of the salivary glands; parotid gland being the most common primary site of origin. The tumor may also very rarely originate in minor salivary glands of the base of the tongue. Due to rarity of its occurrence, histogenesis and clear cut therapeutic guidelines are not defined. The present report describes the case of a 48 year old male who was diagnosed to have a tubular variant of epithelial-myoepithelial carcinoma of the base of tongue, Stage T3 N0 M0 (Stage group III). The patient was treated with neoadjuvant chemotherapy followed by radical radiotherapy (Rt) and is alive with no evidence of disease 14 months following end of treatment.
