Case Discussion

Knowledge of the anatomy of the oral cavity is imperative to understand the site of origin of the neoplasm, the pattern of spread and enables documenting the stage of the disease. Herein we have an oral cavity neoplasm that appears to originate from the anterior tongue to spread into the floor of mouth invading structures as described. When multiple spaces and fascial planes are involved, assessment of crossing of mid line and bony involvement is mandatory.
