The majority of the lesions, like those seen in the palate and tongue, were sessile and had a smooth surface, whereas the others were pedunculated and had papillary projections (Figures 1, 2 and 3).
View of the bilateral jugal mucosa and the soft palate showing multiple sessile nodules and some projections, resulting in a cobblestone appearance. In the hard palate, one can observe some reddish papillomatous lesions.
