Oral cavity examination demonstrates a 2.5 cm proliferative mass over the left retromolar trigone adherent to the underlying mandible with loss of sensation over the left chin (see Figure 4.1). There is also a palpable 2 cm mobile left submandibular lymph node.

FIGURE 4.1 This intraoral photograph shows the lesion of the patient's left retromolar trigone extending on the left mandible body.

Question: What is the most likely clinical diagnosis?

Answer: In view of progressive proliferative growth, with loss of sensation over the distribution of mental nerve with the risk factors of past tobacco use and current alcohol, the most likely diagnosis is SCC. In the presence of a gingival growth, tooth extraction should be avoided as it provides easy access to the mandible through the tooth socket.
