The oral tongue and the floor of the mouth are the most common sites of squamous cell carcinoma (SCC) within the oral cavity, accounting for more than 50% of cases [1,2]. The increasing incidence of oral tongue SCC in young patients (ages 20–44years) who have a lower incidence and duration of tobacco and alcohol exposure suggests that genetic, environmental or viral factors may contribute to the pathogenesis of oral tongue SCC [3–6]. The tongue has a significantly different histologic makeup with a rich lymphatic supply compared to the other areas of the oral cavity.
