History of the present illness

This is an 87-year-old white female referred by her general dentist for the evaluation of a large, irregular, mostly superficial and ulcerated red and white lesion on the left lateral and ventral surfaces of tongue of unknown duration (Figure 1). The lesion was described to be associated with a badly broken molar tooth with sharp edges which her dentist had smoothed out three weeks previously with no resolution to the tongue lesion. She was subsequently referred for a biopsy. The patient complained of pain.
