History of the present illness

This is an 81-year-old white female whose chief complaint was that her partial denture was impinging on the right side of her palate, where a large swelling was identified.  The palatal swelling was of one month's duration.  The partial denture pushed into the swelling, causing some tenderness in the area.  The swelling was diffuse, soft and deep with red overlying mucosa and a groove (Figure 1).  It was described to be 2.0 x 1.0 x 0.75 cm in size.
