AN 8-YEAR-OLD boy presented with a 1-month history of a painful tongue lesion. He was in good health and without complaints. He had no fever, chills, or weight loss. He wore a quad-helix palatal expansion prosthesis for a narrow palate. Physical examination revealed a 1 × 2-cm ulcerative mass on the posterior right aspect of his tongue (Figure 1). The findings of the rest of the physical examination were unremarkable.
