Mucoepidermoid carcinoma of the base of tongue [Carcinoma mucoepidermoide della base della lingua]

Mucoepidermoid carcinoma (MEC) is the most common malignant, locally-invasive tumour of the salivary glands, and accounts for approximately 35% of all malignancies of the major and minor salivary gland. Minor salivary glands are scattered in different areas of the oral cavity such as palate, retromolar area, floor of the mouth, buccal mucosa, lips and tongue. MECs of tongue base are not common. We present a rare case of MEC localised at the tongue base in a 42-year-old Caucasian woman and discuss the histopathological types, management and review the literature. Adequate intra-oral excision was the treatment of choice in this case and in low-grade MEC. Prognosis of MEC is a function of the histological grade, adequacy of excision and clinical staging.
