Upon examination of the lower jaw, multiple nodular, well-rounded smooth mucosal proliferations were seen at the labial aspect and the left buccal shelf area on the lower edentulous ridge.  Figure 2 shows the papillary-like bodies at the lower ridge.  Figure 3 shows a closer view of the lower edentulous ridge with the papillary nodules at the labial aspect of the ridge.
